Well, it is like any of the other popular American smallblock V8's. Decent power in stock form when well maintained, and enough potential left in it to be very responsive to common aftermarket speed parts like a 4 bbl, headers, etc.

My stock 318 liked an "RV" cam, a $50 used Performer intake, a small 4 bbl and changing the single exhaust to duals (Stock manifolds even)

I was planning on going 408" with my 360 Mag. but layoffs 2 years ago had me reselling my stroker kit and keeping stock internals, just buying pistons/cam, intake, etc. It'll still make a ton of power as a 360, compared to the 318 I was used to.
