the stock long block is good for about 400 crank hp with just a cam, intake, and exhaust change.



Really...??? I know they're very underrated, but that much?

How much cam are we talking to make that? (I'm assuming an RPM intake/proper carb and full longtubes/GOOD exhaust).

I am THIS close to selling my big block parts for the Challenger and looking for a drop-in 318 or 360 Magnum.



whatever the cam specs were in the 380hp crate motors... Mopar muscle put the 380 crate on the dyno and made like 408 crank hp. I'm thinking it was up around 230° @ .050, 110 LSA? maybe someone else can say exactly what the specs were on those crate motors. the heads as cast flow in the 200 CFM range, which is good for 400 hp if you get a cam that uses all that CFM. but, like I said, the stock intake isn't going to be making 400 hp, because it's all used up by 3800 rpm.



I agree 100%.

A local guy bought a 380 crate engine for his Cuda and using the recommended parts, a 750 Holley and headers- the engine tipped the dyno at 417hp
