Default Dynoed my 389, very pleased.

Nothing spectacular, but a very nice street motor that will be a lot of fun to drive. 1965 389 with 76 heads built and ported by SD Performance. Crossovers filled, threaded rocker studs, hardened seats installed average 72.5 cc on the chamber, intake flow 230 cfm. Lunati Voodoo 702 HFT cam 262/268 duration @.050 and .468 / .489 lift degreed and installed at 106 deg with 1.5 Harland Sharp rockers. Bored .030 over with Ross custom pistons, 11.8 cc dish for 9.5 compression, Scat rods, Butler Melling 60 psi oil pump. Stock Armasteel crank, turned 10/10. Stock intake lightly cleaned up inside, with a Carter AFB off of a 65 GTO. It made 399 hp, and 456 ft. lbs torque. It will be mated to a Extreme Automatics 200 4R with a 3:73 rear end. One run did show 400 hp, and another showed 460 tq, but i for some reason didn't get those sheets.
