415 stroker and 10 psi from a supercharger good or bad idea - Page 3 - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

When you get into better flowing heads, bigger cams, and even blowers to a certain extent, the rpm range the engine "wants" to turn can be high enough that the hydraulic roller cams go into valve float. 4" cranks and even up to 4.125 can be added if the pistons are designed correctly for the block's sleeve length. The big plus to a stroker is the rpm range of the engine is a bit lower for any given level of cylinder heads and cam. You use up the air sooner and you "find" the horsepower that was up into the previous valve float range. Torque is really noticeable as opposed to horsepower-which requires higher rpm out of non-strokers. Take a look at some of the more engine and drag racing related forums inhabited by the 4th gen guys to find proven combination from different manufacturers.

Good idea but if your going to have a 415 stroker im sure you will have forged motor top to bottom, why not 15+ psi ?

I wouldnt lower the compression its a joke to go that low ( 8.x;1) and with only 10psi it would be slower than stock lol. With 10 psi I would go with the stock compression and forged pistons
