What headers did you get 1 3/4???
What was on there before the S&B kit??? Did you guys re-tune the air flow tables for the intake???

 

Are you still running a Stock Cam???

 

Sub'd. I'm thinking about going with a 278mm circle D

 

1 3/4 cal speed headers. Same 4" tube just the s&b air box and filter vs an open spectra filter. And yes still stock cam. I was just expecting a few tenths on the big end since it picked up .3 in the 60ft.

 

I think your just finding the limits of the stock cam on the top end.

As you can see with the convertor your getting out of the hole much faster.

On the top end that thing is a dog. If I remeber the stock cam will fall flat on its face at 5200 RPM which isn't far from the 3200 stall thats in there.

I don't think the headers are doing any thing for you on the top end with that stock cam.

Time for that Cam Upgrade!!!

 

Im gonna agree with you 100%! I believe I'm gonna go with a tsp 220 on a 112 with my recently purchased tsp 2.5 862 heads along with a .30 mill.

 

convertor is not efficient up top. lower your shift points and it'll pick up. you're over revving it.

 

I'm shifting it at 5500.

 

Just to update... It was hitting max rpm in the etc table! Maxed it out it was good to go! I did the cam since then, and recently bought hp tuners pro to learn to tune myself.
