LA360 compression

I'll toss my2c in here as I just freshened up the 360LA last summer in my 74 Challenger. It's not high compression either, build thread here: 360 LA installing Promaxx Aluminum heads. The smaller closed chamber heads got it just over 9:1 using a stock thickness Felpro 1008 head gasket. It has .030 (dished stock pistons) that are .100 in the hole with a mild cam .480/.480 using 1.6 ratio rockers, and Promaxx 63cc aluminum heads topped with an air gap intake and Holley 625 & TTI shortys. It's not a dog... pulls my Challenger around town just fine. Unless you are chasing ET's at the track.. 400HP~400Ftlb torque is plenty fun. Run it as is and don't change a thing.
