I was at Roadkill Nights in Pontiac MI and they had a chassis dyno. I was strapped in and made a few pulls and feel like something isn't right with this.
A fresh build 440, 30 over, Hughes cam, forged pistons, alum heads with 84cc chambers, 1.6 ratio dbl roller rockers, msd ing, M1 single plane intake with 800cfm Holley 4150. My ignition didn't have enough on the top end it was kind of popping, and AFR was 13.5 on the top of the pull. 3.55 rear gear with sure grip. OE wheels
So I know it needs more fuel on the secondaries but the numbers don't add up, only 250 hp to the wheels?! It torques up super hard and plants the car, and rips.
I attached the dyno print off, and a link to some of the runs.
