Slewfoot 6.0

Ok guys, i have an 81 c10 with a 6.0/4l80e swap. The 6.0 is a stock shortblock, stock ported heads, asa cam, ls6 oil pump and lifters and an edelbrock performer intake and 750 carb. It has 12 bolt rear with 3.42's. Now the question is, what size stall should i run. The truck will be driven 50% street, 25% strip and 25% medium towing. I plan on pulling my 89 Iroc-Z to the strip which is 180 miles round trip. I have a huge trans cooler, so heat shouldnt be a prob. Im torn between what size stall to run. Ill probably put the 4.11's back in at some point, maybe not. I was thinking about a 3200, 3600 being the largest and no less than a 2800. What do yall think? Any help/advice would be much appreciated.

We have our 278mm option that sounds like it will compliment your setup very nicely. What are your cam specs and what flexplate do you have?

Its an ASA cam 226/236 .525/.525 on 110 lsa and a stock flexplate

I think our 278mm will be a good choice, towing and performance.

You could step up to a billet converter, but I don't think you need it.

Nah, a billet verter wldnt be needed on this set up, maybe my pros street '69 z28, but the question is, what stall speed...3200, 3500??...

I kno they say get a stall abt 500rpm over peak tq, but i dnt have access to a dyno, so i have no clue as to wat hp and tq itll have...im guessing appx 460hp to the crank...just trying to figure out stall size in rpm...

I was thinking the 278mm 3000-3200 to get you performance and towing all in one. Your cam would probably like a little more RPM for the best performance, but that might get a bit aggressive if you tow often.
