Now THAT comment is Bull$hit.

For reference, here is the original post:

The thread title of course defines "these heads" as Advanced Inductions 200cc Trick Flows. These are "500hp heads". That is, if they are bolted onto a "500hp block". Meaning a cam that will allow the heads to breathe well enough to work and a block that will hold the rpms & power.


Are you following so far?

The guy who started the thread wanted to know about bolting these heads onto a STOCK BLOCK.

He did make a followup post about what he'd like to do in the future, but if he buys these heads NOW they are going onto a STOCK BLOCK. (According to the original poster's own words.)


Now, except for a could of rocket scientists who thought that would be just a NIFTY idea, the OVERWHELMING MAJORITY of the respondents on this thread tried to dissuade him from doing so on the basis that the A.I. 200cc TRICK FLOWS are NOT a good match for a STOCK BOTTOM END.



And as for YOU Irish...
I know how to read quite well. Maybe YOU should pay more attention to what you're writing.

YOUR POST... YOUR WORDS, said that you were looking at putting those heads on a STOCK BLOCK with 63,000 miles. Any attempt to claim otherwise is absolutely false.

What you're trying to do is hold me responsible for not looking into the future to see your NEXT post, which was completely different from your first.

In your NEXT post, you said: "i am just trying to get some insight as to what heads and cam package i should go with"
Well guess what skippy...
That's NOT what you said in your FIRST post, and your SECOND post was AFTER I responded to first.

In case you forgot what YOU SAID in your first post, here it is:


So how about YOU go sit YOUR @$$ in the corner.

While you're at it, consider checking your headspace & timing.

And next time, don't blame OTHER people because you can't keep track of what you're saying in your own posts.

 

I would call that an extreme example.

 

Chill out guys..

Anytime your head flow characteristics change (whether it be stock ported or aftermarket), you should get a cam designed to take advantage of these changes, otherwise you're wasting money. Spending $1k plus on heads and then not swapping a cam isn't very smart.

If you're just swapping the heads, then the only way to get your compression right is to mill the heads down. Most of the time you'll want your compression ratio to go above what it was stock, cams with more overlap tend to bleed off some of it. Lloyd Elliot is a good expert on this stuff, you could ask him, you might even end up buying one of his packages. Much better than just a set of high flowing heads bolted to an otherwise stock engine.

BTW, I don't find it hard to believe losing 20 hp dropping 1/2 a compresion point (especially in this situation, while only gaining 10 when going up a full point. Generally an engine has a certain point at which compression is at it's best, after that you'll have to start pulling timing out a bit, which will lower the power gains. Not to mention that it's always easier to lose hp than it is to gain it. Lots of people on this board can attest to that. High compression engines (15:1+) get quite a bit of power out of the high pressures, but obviously race gas is also required. Basically, it's a good idea to ask people that have done it before what a good ratio would be for your setup.

 

i have never run these heads before but they can and will work if you put the matching components. If you get those heads from AI, im sure they will suggest a particular cam that will complement the heads.

Everyone here has there own opinion and which 99% of them you dont need to listen to. You need to do some factual research by getting in touch with AI or Lloyd Elliot <--I personally recommend, and see what they tell you. There seems to be one person on here that has a set and is running them with success. Maybe you should ask him about his setup and see if that is something that interests you.

 

hey lame random name, i guess my origonal post sure sounded like i was damn sure i was gunna buy those heads. i guess when i said, "would i be setting myself up for failure?", was a dead give away that i had credit card in hand and i was ready to buy. or maby i wanted some opinions and insight into wether or not those heads would be good for what i want, but since you seem to have a difficult time reading between the lines,and you felt the need to be cocky, next time ill spell it out for you. Im still having a hard time understanding how you came to the conclusion that i intended to use these heads with a stock cam, especially when i asked about the cam in my origional post.

 

200CC runners to big??????Maybe for a 283CID but ya could make them work on that small of an engine.
That's BS and have to raise the flag.
Ya can't put to much head on it,however ya can put a stupid cam in it and kill the slow driving around town without a 5.36 gear.

BIG heads=SMALL cam for the same HP level.
Stock LT-1 heads are 54CC's and the TFS are 62CC's so an angle mill is in order WITH the intake side of the head cut to compensate,NOT the intake. This way when you want to sell one or the other they don't have to go as a set.

 

forget what everyone else said, just run the trickflows unmilled and take advantage of cheap 87 octane...

Seriously though, like everyone else has said, those heads need a matching cam to complement them. When you're spending that kinda money, you might as well do it right. Similarly, you can't expect your shortblock to last very long at those power levels (>400 rwhp) either.

 

Spare me the excuses.
Your original post was your original post.
As to the cam question, I answered that in my initial response to your first post.

And by the way...
Spare me that nonsense about not "reading between the lines"

That's not only BS, it's an excuse; and the maximum effective range of an excuse is zero-point-zero meters. Or didn't you learn that in Basic F***ing Training?

 

lamerandomname. when did you answer my cam question? all you said about the cam was that the trick flows were too big for my stock cam. i dont think that i ever implied that i was going to use a stock cam. as for excuses, do you have one for being a jerk?

 

How many times do I have to refer you back to my first post on this thread before you actually READ the f**king thing?

Do I have to quotate it for you? AGAIN? Maybe you need me to highlight it for you? Or use the #5 font?

I guess it must be easier for you to mouth off to me and tell me to go stand in a corner than to actually pay attention.

ONE LAST TIME, here is the SAME INFORMATION I gave you in my FIRST response, which you obviously have YET to read....
I'll even bold the important part for you:


Those heads are too big to bolt onto your stock short-block.

However, if you do nothing more than a simple rebuild with flat-top pistons and whatever cam AI suggests, your engine will run like a raped ape.


Did you catch it that time?

Or do you want to argue that it's a bad idea to get a cam recommendation from the people who ported those heads in the first place?

Or do you want me to go back and stand in the corner again?
