Winter Upgrades (Feedback wanted)

I'm finally getting around to installing my new custom Coan 4500 convertor this winter. I'm also swapping my 2" TTI headers for TTI 2.125" headers.

Since the engine is coming out, I am going to make a few other changes with some dyno time.

Currently I run a 950 Proform carb. It's been ok, but i'm upgrading to a 1050 4150 style custom carb.

I'm also going to install a Jesel Belt drive and play with cam timing. I'll make another post about this topic.

I was considering going to a 1:6 rocker, but unsure if this would be worth it for me and how the engine would like it.

Any other suggestions, comments, please let me know.

====================

Engine is a 440, 340cfm 2.20 eddy perf RPM heads, roller cam 260/.650/112, ported victor, flat tops with 84cc chambers

602hp @ 5,900 / 575ftlbs @ 4500


Using your numbers and making a decent guess at your compression ratio (looks like it's between 10 and 10.25:1 so I used 10:1) this is what my math says.

BTW, I picked lobes I would use that keep your lift about where it is. And using 1.6 rockers. Valve speed is king if you can control the valve train.

Anyway, the numbers are close to what you have but different.

257
269
104 LSA
101 ICL

Just a quick look at lobes and this is what I'd use if you don't want to change anything.

298/289/257/.656
310/301/269/.640

Don't let the 104 LSA make your nervous. A good tune up and it will idle and drive just fine.
