421 Stroker with Trick Flow Heads/Intake Dyno - Redux

Bullet's guys picked out the cam. Their thought process was they were trying to trick the heads into thinking they flow more by bumping the duration while keeping the lift around the .600 - .615 area with the 1.6 rockers. It seems to have worked because it's pulling much harder almost everywhere. I also upgraded my carb to a custom 950 IRD and it is AWESOME. The Brawler was good, but this IRD is stupid nice.

I didn't end up putting it on the chassis dyno. Just a series of life things came up this Fall and I didnt have time before the snow started. The car is getting picked up next week to get the cage installed. Once I get a trailer in the Spring, I'm bringing it to our local 1/8th and I'm going to tune it there. That slip is the only one that matters anyway.

She'll be ready in 24'. :)

Wow looking nice, good luck and interested in the results. As far as cam I meant what was the thought process on the regrind from the bigger 250 @ 50 to the regrind 260 @ .50? Was it the bump in compression or just thought it needed more duration. I’m getting my 418 together and I have almost the same bullet hyd roller. It’s 256/261 at 50. 630 lift with my 1.65 rockers. But I am going to end up about 13.2:1 compression, on e85. I want to shift this thing 6600-6700 max so I think that cam should be about right but wondering if I should of had more duration
