421 Stroker with Trick Flow Heads/Intake Dyno - Redux

Starting phase 2 of this 421 build. Time to wake this engine up.

I finally got the car together at the end of Summer and it pulls hard! Of course, I can't leave anything alone so I'm installing a bigger cam and finally hooking the nitrous system up.

Bullet cams got me a new hydraulic roller and we increased the duration by +14 on the intake/exhaust and increased the lift to .611 using the 1.6 rockers. If my math is correct, it should increase peak power by 500-550rpm, which will put me around 6300rpms. That's where I wanted it initially.

I won't be removing the engine to dyno this new combo, but I will be taking it to a chassis dyno in the Spring.

Here's the new cam card:

That should make a nice gain vs old cam. I have a very similar cam from bullet going in my new build soon. 256 261. Same lift on a 110. Can’t wait to try it. I have a 4.1 Ohio crank kit. I was pretty happy with their service
