My old 383 Dart.
Stock 383 block and pistons and crank and rods that I rebuilt. I knurled the pistons and actually honed the cylinders a bit oversize to be true round since I used the stock bore pistons. File fit the pistons for .0015 to .002 clearance and used .005 over rings that came out at .022 eng gap.
452 heads I did some mild bowl blend porting on and cut them a bit for a true 9.5 comp. MP .484 hyd cam on a 104 ICL.
Stock rockers and I used some .015 shims to get the lifters centered so they did not push down to far with the heads milled.
RPM intake and a 750 Holley DP.
CPPA 2" headers and 3" exh with Ultra-Flow mufflers
Stock dist I recurved with the MP orange ECU
stock 727 with TA reverse manual V/B and Turbo Action tight 3000 10" converter.
8-3/4 rear with 3.91's and a McCreary G/60-15 tire.
Car weighed about 3640 lbs with driver.
Best et was 12.31 @ 110. Would always run 12.50's at 108 or better on normal summer days.
It was a nice running street car for the mild 383. Ron
