I am soon bringing my stock 1970 340 block down to hughes to get the machine work and cryogenic treatment done. So now the question should I go with A.) Go with RPMs forged 3.55" stroker crank making 372 cu. in or B.) K1 technologies 3.79" forged crank making 394 cu.in here is why I chose these two with the car I am building I am limited to the headers that are available I will be using the early A body step header from TTI and already am having them modify the collector making it 3.5" instead of the standard 3". I will be using the RHS "X" heads super prepped from hughes engines an air gap intake and a bigs 950cfm stage 7 carb. I will not use a 4" crank because I do not think the headers will allow the engine to work at it maximum capacity. The weight of the car with the driver will be right at 2800# trans is a 904 being built by Rick at A&A gonna use hardened input and output shafts. The 372 I can use a hotter cam and bump up the compression still using pump gas not having a detonation problem do to the weight of the car there for increasing the rpms and hp but losing torq which I feel in my case is no a major issue. Or if I go with the 394 I will increase torque be able to use a taller gear and increase ci there for making up the lost hp from not having the higher comp and more rpms from the smaller cube engine. what some more insite on this help
