I have a cylinder down in my cobra due to too much timing and boost, so Im gonna go with a MMR shortblock and Im running stock heads with the kb 2.2 Car made 650rwhp on 22lbs and 21 degrees timing with a 3"upper and 4"lower on the stock shortblock. Ive been looking at the MMR 5.0 Stroker Mod shortblocks, and I could use some advice which shortblock is gonna be the best bang for my buck. Id like to keep the car around 600rwhp but on less timing and boost. Any suggestions?
