Lately there has been lots of talk regarding the title subject, the 390 engine S code. Im wondering just how great is this motor? From the people i've talked to what i've heard is that the heads really didnt breathe well. Wasnt this motor rated at like 325 hp? is this correct? at what rpm? What was the torque figure? at what rpm? Does anyone know the valve sizes intake/exhaust? how about the intake runner volume? Anyone ever do a Chassis dyno of a stock 390 with a C6 and a 9 inch? how about a chassis dyno of a stock 390 with a 4 speed and a 9 inch? if so what numbers did it pull at what RPMS? How about a 390 with a few upgrades? How about the HP and torque figures of a 390 with aftermarket aluminum heads?
Isnt the 390 a FE series motor? Is the 390 considered a big block? Can a 427/428 crank be used for this block? i dont really know much info about the 390 in general...please inform me
thanks
