what cylinder pressure???
Im planning on Building a Hot street/strip 383 and im wondering about what would be a safe cylinder pressure to run on pump gas with aluminum heads. Im trying to get as much compression as i can without detonation. The cam im going to run builds alot of cylinder pressure quickly because of fast opening intake ramps and faster closing ramps. Im wanting to get the best quench i can and still be safe if problems occur. what is everyones opinions about zero decking the block? my engine builder says he doesnt really like zero decking even in race motors just because of the fact that if something does fail, its not as prone to destroy everything. He says he usually sets pistons about .010 in the hole. Im going to be running good rods and pistons, and i would like to have between 10.0 to 1 and 10.5 to 1 compression. The higher the cylinder pressure is, the more heat is made, therefore the more likely to cause detonation. Im wanting as much cylinder pressure as i can get with 93 octane pump gas and still be safe, with a good quench. Thanks for any suggestions
Oh and one other thing, about how much compression loss can be expected from going from a 64cc head to a 68cc?? thanks
