Well, I found the limit of stock CR & lil cam

it's a 74 Duster, 73 360, never actually checked the CR but it's a stock style piston +.030, the X heads have probably been shaved a lil in the past IDK for sure. It's a 727 with a 10" 3000 conv. and turbo action RMVB, It's got 3.91 gears in an 83/4 with a 255/60/15 MT ET radial. It didn't matter if I loaded up the converter or left soft then went WOT, 60's were 2.0 either way. the cam is the MP 430/450 lift cam, it's got an MSD ignition system w/ mech. advance, headers and 3" exhaust, I shifted it at 6,000 and the mph was 95-96 (it's been 98 in the past) With a little more tuning I suppose it could have run better, but I tuned it to the best of my ability and as I'm just 20 and have only had it done for 2 of the 4 years I've owned it I'm happy. The night before I was talking with a friend who has a nitrous kit for his EFI trans am and I almost borrowed a plate and his kit to spray 100-125 at it but since it was the first time I had it tuned well enough to go full throttle from a dead stop with a 750DP I wanted to see what it'd do, and I didn't wana be up til 3 or 4am putting on the kit and trying to tune it for spray lol. I'm sure there's a little bit left in it with a more experienced tuner but oh well, it's getting redone this winter. I also think my balancer has slipped cuz it seemed weird while setting timing and it broke up bad on the first pass at what shoulda been good timing according to the balancer. Oh it also has a stock replacement fuel pump and stock tiny fuel lines and pickup, changing that though.
