i agree advancing the cam will also help with torque. from what i understand most aftermarket cams produced today are ground 4 degrees advanced. i know that this was true with my Comp Cam. so if you were to advance it say.... another 4 degrees that would be 8 degrees total advance. i have a huge cam in my galaxie .530 lift and .230 @.50 i advanced it 4 degrees and i made a huge difference. the reason i chose such a big cam was b/c i do lots of interstate driving. i can do about 60mph at about 2300rpm and my cam makes powe from 1500-6800 so im right in my power band, and besides i didnt have the money to build a motor that would ever launch that beast of a car hard so i figured i might as well just make it the type of car thats fast from a 60mph roll. the thing is an absolute pig until it gets momentum and then its fast but i will say that the extra 4 degrees advance helped down low. and up high or at a roll with a 3.00 rear end that thing will fly. but a cam like that in you truck just wouldnt make any sense. i know lots of people who build big 4X4's and put huge high reving cams in them, whats the point besides the fact that is sounds cool. my friend had a 383 blazer that he built and i had a .565 lift cam!!!!! (i forgot how much duration but trust me it was insane) he spent a ton of money on the valve train so it would accept all that lift and he had something that was usless for what he wanted to do with it. putting in a huge cm can just kill performance as i learned with my galaxie, i had mismatched parts so i ended up having to spend a ton more money to make it how i wanted it. i had to buy intake (which isnt cheap for an FE), headers and im saving for a set of edelbrock heads. ohh yah and all this stuff id going on a 406 block but for now i have the 352 in it so i can drive it. but anyway thats just my 2 cents
