Is it possible to increase the cylinder head combustion chambers?,
if is, how many cc could be safe in a stock alum. lt1 heads (54.4 cc)?.
have anybody done this?
Thanks.

 

Yeah it's possible, by much I don't know, I don't think more than a couple to a few CC's...

What are you trying to achieve?

 

so, may be I can gain about 4 cc more, I havent run my future project, I´m worried about the dynamic compression, is about 9:1, and everybody says below 8.5:1

 

Eh, post up your future combo and what you've figured regarding compression...worst that can happen is that we don't get the answer.

 

You could run the stock gaskets vs the .039 felpros. That would be worth a little.

 

ive always heard 9.0 and below.

 

You can get 2.5+CC's if you do it right.There are places you can grind through the chamber.9.0 DC is OK for premium pump gas and a tune.

 

Yes, effective, however, not correct/efficient.

 

You can increase the chamber to approx 64-65cc.
I currently have both LT1's & LT4's in the shop with 65cc chambers.

I would not suggest this unless you are an experienced head porter as you could seriously weaken the chamber if too much metal is removed in the wrong area.
