I had the 177 blower on a mild 350 chev but I am building a better 383 chev now with a dart block ,blower pistons ,full roller cam and lifters and rockers.
I have a forged crank and good rods etc etc.I want to run more boost with the new engine but I believe the smaller blower ( 177 ) will heat the engine up due to the speed to provide the boost and I don't want the engine overheating
