COMP Cams 12-423-8 Xtreme Energy 224/230 Hydraulic Roller Cam for Chevrolet Small Block
High performance street machines, 2000+ stall, gears, choppy idle.
This is a great Chevy 350 Camshaft for all round use in Cruisers, Hot Rods & Muscle Cars. Has a very noticiable lumpy idle that is just nice and not over the top. Great street driving manners with plenty of go when you want to lay on the throttle. Pretty hard to go past this camshaft for an all round good choice. Suits Chevy 350's and 383 strokers with DRP alloy heads and a nice dual plane intake manifold with extractors.
