About to order a stall and was wondering if i should go between 4000-4500. Cam and bolt on ls6. Rev limiter around 6800-7000. Gonna be a weekend warrior and a Lil drag strip. Will have lockup. How big should i go? 3.42 gears

 

What kinda cam?

I think a 4000 stall would be plenty.

 

Fti custom grind streetsweeper. 638/624. 237/241. 111lsa iirc. I was thinking 4000

 

4000 will work but I'm no expert. A cam that big I'd have more gear than 3.42

 

I agree with mjs1020. I would run more gear. What type of converter are you looking at? Yank's SS PT series? This is the same situation I just went through. I ended up going with a PT4200 with a pretty big bump stick. The PT has shorter shift extensions compared to the SS. This is why they say not to run n20 with the PT series. Give us a little more info.

 

Why more gear with the cam? The cam drives amazing. I went to 3.42 from 4.10 for drivability issues. I had to run a 28" tire to make it through the 1/4

 

^Because big cams usually suffer loss of low end torque and the lower gears +stall converter will get u quicker into the power band.

 

It has a very broad power band. I could literally put it in 6th gear and go like 40mph at like 1200rpm and it didn't surge at all.

 

Its an Ed Curtis custom grind

 

Okay so problem solved about the gears if that is what works best for you. We was just giving suggestions. Anyway back to your converter issue..

 

I'd go PT4000 all day with that cam.
