compression ratios? |
By Earl Wood - 08/02/2001 11:38:48 AM; IP 204.211.35.99 |
I have 2 sets of head for my 75 390. The set that is on the engine is D2TE-AA (68.1-71.1cc) and the other is C6AE-R (71.2-74.2cc) The engine has stock 75 dished pistons. My question is this..... If I change to the C6AE-R with its bigger ports and larger cc will I need to change the pistons to flat tops or will the dished pistons be OK. What would the CR be with the dished pistons? |
