What do ya'll think about enginefactory crate motors?

Only thing you need to watch on these bigger horsepower 383 stroker motors is the cam and intake selection. Easy to make big power in these with a big cam and a single plane intake. Power is usually way north of the normal driving RPM range. A dual plane intake and less radical cam may make smaller HP numbers but driveability will be better. I have a 383 in my 62 Impala beccause it's a fairly heavy car. It only has 394 HP but has 454 ft. lbs. of torque which starts down nice and low in the band. This is real dyno'd numbers not advertised. I bought a GM Performance 350/383 roller cammed motor for my 65 C10.
