Default NNBS 6.0 or 6.2

A few weeks ago i flipped and totaled my truck

it was a NNBS RCSB 5.3 porcharged D1 on about 10 psi..long story short i took off my supercharger and know im looking to get another truck


I want to come back harder then before..i was thinking in doing a motor swap and maybe a set of heads and cam..what do you guys recommend?

Step1: do i get a truck (RCSB) with 4.8 or a 5.3?

Step2: do work on a 5.3 or look for something bigger?

Step 3: which is better for boost, LY6, L76 or L92 or maybe an LS3

Step4: what do i need to do to bolt up any of these to a 4L60e with a 3600 stall? (i know this wont hold up too long)

let me know what you guys have done or what you think would be my best option..i cant wait to be burnin rubber again..

Find a 6.2 to swap in with your D1. Take a look at AK2007R6's truck. It runs pretty good. I can only imagine how well it would do in a RCSB.

60e bolts right up to a l76. If you've got the spare $ might as well start off big no sense in having to do mods to equal a bigger displacement motor. I woulda grabbed a 6.2 truck when. Was looking but they were few and far and a lot more money then my 6.0. Sucks that rolled your truck make anybody cry especially after time money and blood spent on it good luck on your next truck
