re: Verdict? (Headbytes porting SCAM)
If you'd like me to analyze my first post you linked let's get that out of the way now.
I have been dealing with LT1s for 15 years now and have seen just about everything. Some of the other old-timers like Fred, Rob, Rich, Jason, etc., have been here even LONGER and have seen even MORE. Having said that posters like yourself come and go, propose your build idea, run with it, then come back onto the forums asking why are their numbers low, why the track times aren't what they expect, why the drivability sucks, etc. You posted a recipe that would give less than stellar results. Seen it a dozen times. "Stage 3 port and bowl" means nothing especially coming from an essentially no-name in the LT1 world. And just because he ports "NHRA heads (whatever that means)" does NOT automatically make him a genius in the LT1 community. The 280XFI is a good off-the-shelf cam but for the price there are more advanced custom grinds to deliver exactly what you want. You then say you want to keep your compression around 10.25-10.5:1 which makes absolutely NO sense in terms of performance. Typically performance builds target 11.5:1+. And if you think you can't run that high of a compression ratio on an LT1 you are mistaken. My 383 is closer to 12.5:1 and I've got NO problems and more importantly the RESULTS to prove it. Then you say your shop says your combo should be 450HP. Obviously they mean flywheel horsepower which would translate to about 350whp which is about the same as a good cam-ONLY car on stock heads. Considering you plan on using a 280XFI and these "stage 3" heads and you're only going to get 350whp is pretty sad, hence my comment about starting over. All that work and you'll run neck and neck with a smarter owner's cam-only LT1. I shouldn't even mention anything about the "10s on a stock drivetrain comment" because that's just ridiculous.
As far as why I chose AI heads all I had to do was do a search. AI has some of the fastest if not THE fastest stock-casting headed cars in the country. There isn't just one or two but DOZENS of them reproducing their claims on their website. This is called substantiated evidence - results that are more than just a YouTube comment or writing on a webpage. I could have went with LE, GTP, AFR, etc., but the results that I wanted were being produced by AI. It's fairly simple I am sure you can understand that. And why are you quick to dismiss their customer service when you haven't done business with them, talked to them on the phone via email or in person? You're taking stabs in the dark while grasping at straws.
I get frustrated when I see posts like that where new members come on spouting off their great plan but in reality it's been done before. Making horsepower is easy if you do your homework and I think it is safe to say you simply haven't. I don't mean that in a negative condescending way but as an obvious newbie you need to be receptive to constructive criticism. In other words, take your own advice.

I will post dyno results and we'll see how your claim holds up. I am sure that the motor will make more then 350hp when a cat. gutted tuned car will make over 300hp. That assumption is just absurd .

If you HONESTLY think we should be impressed by "buckling quarter panels" on a third gen you're trying to impress the wrong crowd.
You might be older than me but you certainly lack the (important) LT1-specific knowledge and it is blatantly obvious. My original post in your other thread was meant to turn you around and point you in the right direction. I am sorry if the delivery was harsh - it was not meant to be.

I guess I finally have to pipe in lol. I wish I had known what I know now about lt1 and how to make power with them and things to avoid and everything else. Let me say I had two years of downtime before I spent a dollar to get my car going again. My research was based on mostly older sbc power as thats all I knew other than some of the newer turbo stuff. Well I finally sttled on what seemed the most hp per dollar I could get and its a forged rotating assembly 383 long block with ported heads and custom cam and arp headstuds and arp bolt upgrades and 1.6 rr. I got this for under $4000 delivered. Guy had good reviews and owned lt1 car and machinist for 20+ years. Well long story shortened that is an incredible price but I dont know what I have and ive pulled motor basically 3 times and have some tuning issues and possible bearing issues. If I had to do it over again I would have went heads cam from ai or le and had someone reputable do my shortblock or take the time and learn that myself. If I can ever get my tune squared away and run spray like its meant to do I will have between 550-600 to the wheels but still wont put as good of numbers as Joe with a 100 or more hp. I quicky have become a fan of whats proven because as of yet my gamble hasn't paid off. My motor is strong as she will break it loose shifting into third gear at over 60mph on motor but I dont have reliability yet. I also have doubts if I am going to have any life out of it. I am tempted to pull the motor and just go through it and really assemble it. its like having a hot woman whose personality annoys the crap out of you lol. Right now in my life proven performance would have been worth every cent and who knows I may have a heck of a motor for the cost and just something stupid preventing me from being able to get the tune on. Or I might have five more things that I havent fixed or corrected that are there from negligence or ignorance. Seriously I had at least 6 headstuds seaping water with no pressure in the coolant system. Builder also said run stock pan without windage tray which I corrected when I pulled motor back out to seal headstuds correctly as he used teflon tape. I changed so many parts all at once with the new motor its tough to determine whats the problem. The plus side ive gained a buttload of experience and knowledge and understanding because ive had to learn and redo and find and try to solve and replace just to get were I am now at and im not done. in fact not even safe to run a 1/4 mile yet. Theses guys who have years of experience are the voices of reason almost as they have seen so much of what works and what doesnt and I would rather know something works than hope something does and save money. That head porter may be the next big thing or he may produce some hit and miss or it may be all miss. Time and customers will tell and often you can learn more of picking up a little here and what you could lose there with experience.

re: Verdict? (Headbytes porting SCAM)
wow is all i can say to the OP, Ramair95TA has done nothing but help me when he replies to my posts and i really feel like apologizing to him for getting the backlash you have given him. He doesn't come on here to bash but to help. If i were you I would have just posted what you are doing and keep quite until your car was back together and done with its first couple dyno pulls.
I just got my car back together with AI parts and im HOPING for close to 400 rwhp, but that might be wishful thinking and ill take what ever I get as long as the car is running healthy. I may go with a bigger cam later if my HP goals aren't met but ill never lay claim to what it will make before its even together and tested. you got all this "it should" remarks in your posts. What we are wanting to know is what "it will" put down and what “it will” run, the only way to know that is to get it running, on a dyno and down a track. Good luck to you tho, I don't wish anyone bad luck. I hope your very happy when its all said and done and like other ill be waiting for those dyno numbers and track times to substantiate your claims.

I had trouble pulling the link up but it's there and when I spoke with Golen he confirmed.
I also find it funny that in your previous posts you mentioned that the XFI cam delivers good power yet here you claim I wont see over 350 rwhp can you please elaborate before I post my dyno results in the coming weeks of my generic non branded heads.
Here is the quote "What year car, transmission, current modifications, etc., are all needed. It should be mentioned that the XFI grinds have been proven to make decent power though."

PS:
I am way beyond trying to impress people.

Find ANYWHERE where I snub my nose at the XFI grinds. You won't because I ran one back in the day cam-only. I said they are good grinds however with your lofty goals I would run something more custom.
Chad Golen is a terrible businessman who builds terrible motors so take anything he tells you with a huge grain of salt.
You continue to have the mindset that I am attacking you but I have made myself abundantly clear that I am voicing my experience with the platform and that you may be making a hasty decision - that's all.

I am betting that after the dyno tune and with super unleaded (not even race gas) that it will be close to my range of 430 rwhp. So stay tuned, I will have them numbers.

re: Verdict? (Headbytes porting SCAM)
you mean grade 8 header bolts? or maybe eighth grade? Or maybe you wanted to say " I went to eighth grade but I didn't learn about grade 8 bolts."

Stage 8 is a brand of locking header bolt. Stage 8 porting requires locking bolts to keep your headers from blowing off.

All I know is when I pop my hood after blowing a door off a car with a set of aftermarket heads, mine will look stock and with a 113 lsa sound it to. You have your goals I have mine with a twist. You want faster 1/4 miles times I look at the whole package, can I drive the car in traffic, can I run my AC at low rpms, do I need crawl over a roll bar to get into the car, can I get my kids in there? I like the sleeper, you never see it coming but sure as hell you'll see it going. Realistically what am I losing over a custom grind cam? At tops 30hp and we all know HP sells TQ gets you down the track.

For the record 280 xfi cam will be perfect for a nos setup, he needs to do his homework better and stop following people like some little puppy.
As for you twinkle toes stay out of it, do your parents know you are here trying to troll the forums?
Can't help it if he didn't realize after the third time saying "lets discuss this after my dyno results" I was trying to end the conversation because we are on different pages. You would think a mature individual would pick up on this but now I have to sit here and spell it out for you guys.
