right now cam is 8-305-8 114lsa 110 centerline duration 220/230 @.050lift .51/.51 valve lift

I run 1.5 rockers and a d1-sc with a 3:10 pulley runs 13psi at 5500 pulls 512hp/514tq at the wheel

want to install 1.6 rockers and a 2.75 pulley what do you think I can expect from that change....max lift with 1.6 will not exceed springs limits

 

anyone???

 

Pm blown 06. Not sure how much he's on. Good luck!

 

Fair amount of overlap in that cam! Must sound healthy.

As far as the lift... Really depends on your heads. What heads do you have?

A prochsrger guy will chime in on boost and possible power increases on that side. This isn't really hard question to answer... Best bet is to do it and find out lol.

You ever hit NED? I'd like to see what this truck looks like now. I remember you from the old Chevy truck world days.

 

I am running trick flow 195's

have not been to ned with truck yet....wanted to get the tune right...so I can drive it home.....here is a pic before 22's

 

anyone else?

 

Wow a very unique very cool build. What are you using to tune?
The added lift and boost should increase things a good bit. The lift will be approximately 9% over stock. So about .55x/.55x which will mean greater efficiency over current settings while adding a little more stress to the rockers themselves. This I expect will be especially helpful with the exhaust side. The smaller pulley should increase the boost a couple pounds. All the ricer math added together I would guess 75hp jump.

 

dynamic efi and tuner pro and tt-1 wideband ...works flawlessly
