Ok, so try and hang with me for a minute. So I have a '64 Dart. Its latest setup was a 360/4spd/8.25" 3.55 SureGrip that ran 8.60s in the 1/8th mile and was very drive-able. This wasn't enough for me, so I've since pulled the entire drivetrain out front to back with plans of a 340/416 stroker with a 4spd and 8.75". This leaves me with a perfectly good, low mile 360/4spd/8.25" with 3.55SG setup laying around. Enter, my '70 Duster. So early this year I acquired a '70 duster 318/904/7.25 car that is overall decent, but the drivetrain is garbage. So the obvious thing to do is put the Darts old drivetrain into the Duster, 4spd and all. The 360 in question is a '70 360 +0.060" SpeedPro H116CP pistons measured 9.3:1cr 587 heads as cast 1.88/1.60 valves LD340 with a Street demon 750 CompCams 268AH10 with matching springs 340HP exhaust manifolds So before it goes in the duster, I'm gonna freshen it up a bit. I have, on the shelf, a CompCams 484PP cam and a set of 2.02" intake valves. Would it be worth it to throw in the choppier cam and bigger valves, if I plan on keeping the 3.55 gears and HP exhaust manifolds?
