Default 1972 gto 416 ls3

Hello, just wanted to post my project. Its a 72 GTO that im planning to 416 LS3 swap. Gonna get a texas speed rotating assembly . Still dont know about cam and compression and tune for a daily driver. Recently finished work on the chassis and body work and strengthening the 8.5 10 bolt . So far ive bought all UMI suspension and viking coilovers, 2010 camaro SS brakes and rotors and Kore3 hubs and brackets, 06 GTO seats, fuel tank/pump, terminator x, brand new T56 magnum and mcleod clutch, LS3 out of 2011 camaro. Currently stuck on wheels(what i want is a bit out of budget), a hood because i cant find one anywhere that doesn't need pins, and steering. I dont know much about steering, but ive heard that a rack and pinion is the way to go for a sportier feel and better handling for hard cornering. Im also planning to get a vintage air ac system. End goal is procharging to 750whp. Its gonna be a daily driver. Sorry for the long post, but with the quarantine and all i had nothing else to do. Would also like to post vids and pics from my phone but i dont know how.
i hope this link works.

Definitely go with rack n pinion, It takes all the sloppy joints out of the steering so it has better control and feel.
Junk the 10 bolt at that power level and go with a 9" unless you can find a deal on a ready to drop in 12 bolt.
Compression and boost are going to depend on the type of fuel you plan on running and if your going to spray water/meth to keep detonation at bay under heavy boost. If you have a steady supply of E85 then you can keep compression up quite a bit.
I run the same brake setup on an S10. The only downside is the limited wheel and tire size needed to clear the calipers and ride qaulity, I run tubular control arms/ stiffer springs/ larger sway bar/ Bilstein shocks/ Urethane bushing and mounts everywhere, Nitto Invo's 275/35/18 on 18x9.5front and 325/30/19 with 19x12rears and to be honest it's a blast to drive, It will out corner most cars on the street but at the expense of ride quality.

See your other post regarding my opinion on rack and pinion conversions for A-bodies.

Rack and Pinion in an A-body in not the way to go. Buy a quality close ratio steering box from Lee or one of the other vendors, if the budget allows get a 600 series Delphi unit from Turn One. I have a 600 series box and it feels just like a R&P.

Why is that? My buddy had it installed on his Chevelle when they installed a Hotchkiss kit and he loves it. Steers faster and took all the sloppiness out of the steering.

Nice setup you got there. Im gonna run 93 or 91 gas . E85 isnt available as much. Im gonna run the 10 bolt till it breaks and then gonna get a 9 or 12 bolt.

I have yet to see any rack and pinion conversations that don't result in added bump steer issues. The biggest improvement to the stock A body suspension comes from taller spindles. Speedtech has the best ones.
