question on 94 stock mustang heads

[derrick2119]

Does anyone know how many cc the stock heads are? Im looking at a set of flat top forged pistons and it says with a 58.2 cc head it puts out 10.13:1 compression...Im planning on having the block decked .020 and possibly the heads milled .020 also...hoping to get higher compression...w/o breaking the bank!

The chambers in the stock E7TE's are roughly 62cc.

any idea what it will take my compression to?

9.65:1 without decking the block/heads. Each 0.010" decked from the block increases the CR by 0.20:1 and decking the heads by the same amount increases the CR by 0.13:1.

why are you doing forged pistions and keeping the stock heads? Are you doing to work yourself?

Sounds like he's building a nice short block now since it may need a rebuild anyway. THen do nice heads later? That's what I would do.

Yeah im doing a short block right now...thinking about a set of trick flow heads down the road but have been told that AFR heads are better by a few people. Sat down and done the math by the time i get all the machine work done on stock heads i could have a nice set of aluminum heads

Noticed you said you had the AFR heads do they put out as mush as the trick flow twisted wedge heads?
