So I decide to use 3.5L V8 Small Block, actually this engine was taken from Flat 6 FZR, but I change it to V8, and make some adjustment so it will scream up to 7k rpm, not so high? yes I know, but my projection is to Small Block engine which still uses Push-Rod, and all we know, Push-Rod engine couldnt have high rev limit because there's ton of reciprocating mass on each part that will break into failure if revving too high, as how IRL push-rod engine does
also, since it rev limit was lower, so I put V8 Crossplane instead StraightPlane, since CP engine will generate power so good starts from low to mid rpm range
pardon for my OOT, TL;DR, the engine spec will be 3.5L V8, 7400rpm (safe limit so the engine will never overrun when accidentaly downshifting twice)
