I found some of the original sheets from my first dyno session on the 511 C.I. 400 stroker motor with the 906 iron heads and some from my current 400 block 517.2 C.I. E85 bracket motor.
The pump gas motor made 550Ft lbs. at 3000 RPM, peak torque at 4200,4300 and 4500 RPM of 633 Ft lbs testing air cleaners, peak HP was at 5500 and 5600 RPM with 605 HP.
My current bracket motor has a set of ported 440-1 heads with a set of Jesel 1.55 paired shaft rockers, Ultra dyne solid roller and a Indy 400-3 Intake with a A.J. Casselini converted Holley Dominator Compression ratio varies from 14.72 to 15.03 to 1.
I had issues with the Mopar bonze oil pump drive having the gear on crooked on the shaft or something causing it to make the distributor housing wobble making the timing goofy We set the timing and made three pulls before I saw the problem with the distributor moving
That motor made 591.5 Ft lbs at 3900 RPM with416. HP, it made peak torque on that pull at 5800 RPM making 673.7 Ft. Lbs., peak 767. HP was at 6200 RPM , torque was still 649.7 FT lbs. at that RPM.
IHTHs.
