Hey fellows, newbie to the forum, don't know anyone form here except one member, have some questions that you all might be able to point me in the right direction, I drive a 99 GMC that currently had 4.8 to 6.0 swap, trans rebuilt with TCI cluthces , band and seals, Trans-go shift kit, 3.73 lsd factory carrier, and Nelson Perfomance custom tuned Pcm, run good for stock motor truck, but plan to make it a little faster, main focus is on my 78 malibu project, working on a 496 BBC planning to put down 650-750 hp on motor, and an extra 250 shot of nitrous, maybe 10 in the 1/4 hopefully. I work in tha automotive industry, fix cars and trucks for a living, and bolt on mods when needed, I have a boss that's a gear-head and that I get to do all his mods. Next project is his 5.3 to 6.0 LQ9 conversion, should run fast, see in a couple of weeks, well hope to hear from anyone interested, and hope to be helpful as well.
