Made a few pulls today on a 426 wedge. The motor initially made 380 hp a few weeks ago. I thought it should do better so I pulled it down to see how it was setup. The motor started out as a 413 truck block, was bored to 4.25", my friend screwed the motor together with so e-bay parts. low compression max-wedge pistons, comp cam solid .525/.525 lift, 516 heads, torquer intake. After checking I found the compression was 8.44-1, I had a set of 452's I'd milled .100+ and installed them to bring the compression to 9.4-1. No other changes it responded on the first pull by going 412hp&469ftlbs. I then pulled the torque intake and installed a M1 single plane. The M1 picked it up to 417.6hp&480.4ftlbs. I then installed a 2" open spacer and it went 427.1hp&487.5ftlbs. All pulls were using a holley 850 double pumper, no carb tuning was done, A/F ratios were in the high 12's to low 13's. Some hp was probably left on the table as I was still running 100+ octane fuel.
Next up will be a thermoquad.Dave
