The Mac' Attack

[BigMac]

Not all 220s are built the same. The thunder racing version i believe is more in the .551/.551 lift range. The LS7 spring are good to .550 or .570 or .590 depending on who you talk to. Darnie1987 has a 5.3 with that same cam and stall on 33" tires and can't get traction to save his life so should be good for you as well.

Cool, well it should go well with my 35's and 4.56's I have sitting in the shop.

With my new job I barely have time to even see my new house, much less work on my prerunner - the Frac industry is going full speed in West Texas. I should have more time to work on it soon though.

Update... the CNC at the machine shop will be available for use again soon so we can finish our spindles. We have all 4 cut out, just making the final dimension cuts and upper/lower ball joint mounts. We have the code lined out to cut out our lower and upper arms, we'll just need a conference call with Jess on setting up our Kings up front.

As far as my drive train up grades, I scrapped the cam idea and donated/sold my stall to a friend for his build and will just be looking for a 6.0 4L80 combo to build up and possibly turbo. Which 6.0 should I go with for the easiest swap and best power options?

If your looking to go turbo I would just go with a 01 up lq4 they are lower compression than the lq9 so it would be perfect for a turbo build.

When ever your ready, let me know.

Updates...







Not sure if I posted this yet, this is the cutout for the rest of our spindles out of some 1.5" Plate.

Looks good man. I can't wait to see it welded up. Quit workin so much and build your truck already.


Wait till you see what we did to Mic's truck this last week.

Hey, I get my company truck this week hopefully... so now I can cut up this one and put all this heavy steel on.
