WCCH L92 stage 2.5 heads....

 

What are you using for heads Tim?

 

Can you cut a better 60' if you flash the converter?

 

Vinci trucker cam here. I definitely think more exhaust duration would help your setup.

 

stock 317s
I will have to try and see, Only got two test runs yesterday cuz the timing lights broke at the track

Cool, i know more exhaust dration will help, but will it knock off the extra ET im looking for???

 

Looks to me like you need more verter. I could see a couple tenths, and 2-3 mph from a little more exh duration but you mph is already better than your et. Prob with 4-500 RPM more converter, an Isky 221/230, .575/.592, 114, and put it on E85 you could have 11's... You at least need a good meth setup on there for gas..

 

I agree with stock48, if you're truly going after track times, then a bigger verter would definitely help. Either way, you could squeak some more power out with meth. As Beatdown Z stated, you may be able to see a better 60' by flashing the converter.

 

I agree with all the other posts also and here's a few ideas.

My truck 60's better when I flash the converter.

A blower cam will help but by how much I don't know.

Your et/mph seem to be similiar to other 80e set-ups.

I would try meth first myself because the timing your adding currently is probably being pulled by your tune.Do to high IAT's.Also add boost with the meth and timing.

See where that gets you and then change the cam if you want.The meth will help no matter what cam you run.

The added power will make the converter slightly looser too.

My trucker cam has a lumpy idle.

Man my post is a bunch of random ideas do to a small hangover-
I'm on vacation and drinking is the only real plans.

 

Personally Tim, I wouldnt go crazy on the cam size like I mentioned before. You are already really working that 1900 and a big cam will only make matters worse. I would do around 10-12 degree exhaust bias and keep the exhaust duration in the 226-228 area on a 115 or 116lsa to keep the overlap in check. Stock heads so no reason to take the lift past .590

Dont expect allot of lope, you know my specs and its barely noticeable. Gear heads notice it but other then that it just seems to idle a tad rough. haha

 

I've got a 214/224 115lsa sitting on the shelf I think is going to be about perfect, in your case I'd go for something close to those specs.
