I'm not building it for drag racing, I'm going to do some track days on road coarses. The MPH will tell the story though if I can't get it to hook at the drag strip.

Man if I had a car that ran as fast as yours with that mild cam... Id leave it alone!

I see on here all the time SAE dyno numbers well above 400 hp but track results that point otherwise. The only corrilation I have seen is the guys generally running really fast always live down south where the air is better. Dyno numbers will be close to the same from CO to FL because they are SAE adjusted but track times are not which is why they are so drastically different... at least thats how I see it.

Knowing Brad he probably didn't read that you blew a head gasket and you had to pull them. Also though there are guys that have a great running setup and then they end up upgrading parts and going slower, or making less hp. Turbo knows that all to well.

If you were sending them to Ai, 75% of these posts wouldn't be happening.

You clearly are a big LE/BRE supporter, nothing wrong with that. I have sent 3 sets of heads thru LE and ordered a cstom cam thru Bret awhile ago. I am interpreting it as SS RRR thinks that the flow numbers probably arent right and that they are probbaly better than the owner thinks. Bench's vary big time. I had my "308cfm" LE AFR210's flowed locally and they peaked at 278cfm with the same flowbench setup. The local flow bench has not seen a set of ported stock LT1 castings above 25xcfm though. Its all relative. Point being the 278cfm didnt bother me because it still flowed 30cfm better any LT1 head had on that bench. If you compare LE's bench, my 308cfm AFR210's are about 30cfm better than is standard stock ported casting stuff. Its all good.

Point here is sometimes pure numbers dont tell the whole story.

Sarcasm I presume? Can't post for anyone else here who has doubt, but I'm in no way loyal to one shop. I've had my dealings with a few shops that have turned me off to their product. It's been a long time since I've been convinced of any one shop being superior or "better" than another however as of late my research has not been as thorough.

Jon,

It's not even that, they're stuff is on my car.. yes. I don't have any real numbers from my car yet, so it's hard for me to take a firm stance.. judging from the feel of the car I think it will do very well. But #'s do the talking, and I should have those soon (tranny is on the way back to me).

It's really just that all the usual suspects come out of the woodwork whenever LE is mentioned, and it gets old.

Question their 125 mph HR cam and LT1 casting cars though... and watch out.

I've been aching this past year seeing all these threads and dealing with a year long build with my car... granted, I've changed the *entire* car this past year. I miss being able to talk **** and stand behind it 100%

I don't think I've put you in the Ai nutswinger category, but I do admit sometimes I confuse you and SS MPSTR

The Ai versus LE is rediculous and the usual suspects are always invvolved like you said. No worries. I am hoping to get my car back together this summer and break in my 8.5:1 383 with the LE AFR210's and a little 224 cam... I'll post numbers, but I suspect it will only be in te 360-380rwhp... till the T88 turbo goes on

Seeing as how you can pick up a set of used heads for around $250 shipped, I would have gone that route and just put your current heads on the shelf. A few mention crappy looking ports, and then some say they must flow better then you stated. As I see it with that kind of MPH, the heads must love the cam, or the cam loves the heads. You get what I'm saying, the combo works pretty damn well. Keep your heads if it's not to late, and have a different set done up. If the new ones don't justify the cost you can still get most of your money back. It's not like there isn't a market for Lloyds heads. Just my 2 cents.

Pot, meet Kettle And I hope you included yourself in a nutswinging category too.

I would be curious to see those heads flowed on someone elses bench too, and have a second opinion on how well the heads flow in their current condition. Clearly the combo is working.

I don't pop up and bash / nitpick on Ai results threads... I usually congratulate and move on.

Can't pot/kettle me on this one.

The pot/kettle comment was directed at the suggestion above. If you can't keep the subject/questions about the heads in question, don't post. You're one of the worst offenders of the crap you bitch about.
