pat thanks for all your time i really apreciate the info and understand fully about second guessing my machinest i just wanted some other opinions because so many people have told me so many things and he is the only local machine shop an i dont know how long he has been doin it and i no he is a big 4 cyl dirt track guy so i just wanted to check around before just trusting one opinion as for heads they are pro comp band 64 cc 190 runner 2.02 exhasust 1.60 intake (maybe i have that backwards) as for rpm when i run it it is to the floor at all times i use to launch it around 2800 in third on 200 ft track and quickly be 6500 to 6800 but that was with 4 speed ive switched to automatic and havent drove it yet so im not sure what stall to run someone said 3500 but im not sure and knowing that 6500+ is alot on a 400 i would like to stay around that so the range for the cam maybe 3000 to 6700 if that isnt to much of a stretch tech guy at comp recommended a 630 lift 262 duration at 50 but my machinest said that was to much lift so im in a pickle there so here is wher i stand the block is being cleaned now i have no pistons rods or cam i have weind alluminum high rise holley 750 tahts really more like a 900 aluminum heads 64 cc 190 runners 202 and 160 and 175 shot of nos the pistons rods cam and stall are what im trying to get info on weight of the truck is around 4500 pounds gear ratio 6.72 it did great with relativly stock parts in 406 for a play truck as in hitting big deep holes that no one else could cross but at the races in unlimited class i was getting killed so im trying to get as much torgue as possible for no more than 2800 dollars with my top end even though i still wont be a threat in my class im also not sponsered like most others so atleast it will get me on the board and when i have more cash to drop on it i will work my way up some more im just goin step by step becuase im only 19 and the rest have been doin this there whole life im trying to learn and work up from the bottom till i get to the top which i dont expect to be soon i have learned this stuff takes trial error cash and hands on experience and guys like you i really look up to and hope to know half as much as you one day

TQ is not going to be at 6500 way lower then that . if your past 4500 to 6500 your looking at HP . guy from comp maybe closer to what i would use heads would work at lower rpm . not a fan of the procomp stuff just check it out good buy good valves and set of springs like PSI . or Pac
