Is there anything adjustable under the valve covers of a 360 magnum? I have the 300hp 360 crate magnum and am trying to figure out what else i can do to squeeze a little more torque out of it. I am currently unning long tube hedman hedders with true dual exhaust 2 inch pipe with n h pipe and 24 inch glass packs, running a dual plane edelbrock rpm air gap intake and a 600cfm manual choke edelbrok performer carburetor. I'm running the newer style mopar distributer with adjustable mechanical advance. I have timing sitting at 12 degrees initial and 32 total all in by 2800 rpm. I am not to familiar with whats under the valve covers with this engine and if anything is adjustable under there or not? I have been told i could take the intake off nd have it port matched to the engine to get more power and to have something done to the valves? race prep'd or something like that?
