my motor is built close to the same with a little smaller cam and 3.73's and runs 11.60's on a safe tune 100 shot. so you should see deep 11's easy

I gotta call red neck tommorow and see if a 4000 would be better. also might throw a 250 shot at it. would like to hit 10's.

Re: New motor this summer, time estimates??

a couple friends of mine runs ******* converters and have had pretty good luck with them. Edge actually tightened mine up without asking so the nitrous wouldn't blow past it. only problem with that is I didnt plan to spray it every run I would have liked mine to be a bit looser around 4-4500
