Good 4x4 engine combo

Just thought I'd share my experience with anyone interested.

My engine started out as a warmed over L82 spec 355 engine with 882 casting cylinder heads milled 20 and larger valves 2.02/1.60 It had the L82 regrind from GM, I had a Edelbrock RPM intake with a 600CFM Edelbrock carb. To make a long story short this engine ran very good in the upper RPM's but lacked low end power for towing and climbing even with 4.10 gears. No power under 2500 RPM in my heavy truck.

Last weekend I replaced the cam with a Comp Cam EX-4X4 cam and replaced the RPM intake with an Edelbrock EPS intake, my results are very satisfying I have monster low end torque, wonderful throttle response, and a real nice smooth idle. I haven’t towed with it yet but I am sure it will do much better. I didn’t get on it too hard yet but revved it to 4K and it felt just as strong if not stronger than before. I love the low end torque the most I can lug it clear down to 400rpm’s in 3rd and just pull right out by taping on the gas pedal. It would never do that before W/O chugging and bucking around. Anyone looking for more low end torque this is the way to go if anyone is interested in cam specs I can post them up.
