anyone with a 6.0 do the upgrade with a tune and hit the track for a gain report?

 

Ordering the upgrade today. Tracks dont open around here for another month. I believe with proper tuning and such this would give around an additional 75 fwhp. maybe .2-.3 at the track we'll see.

 

Your old et was with the 5.7? now you have a 6.0? what did the 90mm do for you?do you think the vara ram helped?,nice truck BTW

 

Was planning on upgrading but for the money and time and additional tunning... 75hp wet nitrous shot will net much better gains.... "*Goatchs" did the swap and is unhappy with price vs. results. if I were to do it again I would try to fit a front inlet rear drive.... will net lower iat. change rear pulley with no front belt slip.

 

I ran a 13.4 with a Lingenfelter GT-7 cam, shorty headers, Meth, and the 5.3. Ideal conditions though. 68 degrees extremely high pressure front. I never raced the 5.7 I had or the 383. The 5.7 was noisy and a faulty GMPP lifter took out the cam bearings in the 383. I'm hoping to run high 12's w/o meth now. Poss a 4.10 gear change in the future also.

 

Forgot about the 90 mm question. It let me run about 2 degrees additional timing on the top end due to lower IAT's. I would recommend getting a 90 for the 112 and definetly the 122. It really wakes these up with proper tuning.
