Point worth noting: I marked TDC on my balancer and put my timing light on the motor to verify what the MS3x is commanding is what the motor is seeing. DON'T YOU DARE use this curve and expect it to work - way too much timing for most - you'll blow your motor ) Guess not with my build.Īnd my timing curve. I expected the hp peak to be below 6000 rpm, as that's where this cam peaked on 5.7's & 6.1's with a normal intake. Honestly, I did not expect the motor to pull this high with this little cam. Neither of us heard any knock the entire day, including when we tried 2* on top of our final curve just because (dropped power across the board, did not knock though). Craig at Bumbera's was listening, and I was doing the same through a microphone clipped to the knock sensor point on the block. ~300 rwtq from 3,000-7,000 will do just perfect for road racing.Īll on 93 octane unleaded. I wanted more peak torque, but I am very pleased with where we ended up. Ended up with more timing in the higher rpm range than most. We kept adding timing until it dropped power, and backed it down 2* to the previous higher point. We started the day in the 370's (rwhp) using a modified stock 5.7 timing curve.
Straight 30 weight conventional oil for all pulls. Megasquirt 3x engine management tuned by me. TKO600 standard tranny, ford 9" floater rear, 3.60:1 gear with locker, heavy wheels all around. Picked the car up A LOT driving it home.įorged 5.7, 11.6:1 compression, 03-08 GTP Extreme heads, Hilborn intake, custom shorty headers welded by me (around P/S box), 218/224 on 113.5+2 (xfi exhaust lobes- very mild)
