have an 84 Chevy K20 LWB with a 4' lift and 35' tires. I want a little bit of both worlds with HP and Torque. Got the truck with the engine freshly rebuilt already and just wanted some advice and ideas to get it going a little better. Specs on engine are:
1970 Chevy 4 bolt main 400 cubic inch 509 Casting
Bored .030 over (makes it a 406 cubic inch)
Flat Top pistons 9.5 to 1 compression ratio
Comp Cams Magnum camshaft (270 H)
Weiand Stealth aluminum dual plane intake manifold
Edelbrock 600cfm carburetor
Milodon oil pan
GM performance parts valve covers
Carter high volume fuel pump
Hedman Ceramic coated headers
I use the truck for daily driver and mudding as well. I like to have some speed of the line if possible just for fun. Just looking for any ideas to improve the engine.
A bigger carb will help in both the HP and TQ department. Also factory heads are pretty much junk except for vortec heads. Any of the aftermarket heads will give a large improvement in power over factory castings.
