A body with a little twist HOWS IT GOING GUYS. INHAVE ANOTHER OPTION IN MIND.
I HAVE A REAL SOLID 71 lemans wig a protouring suspension that I was thinking about getting rid of for next to nothing but it doesn't sit right with me. The car currently has a Pontiac 400 with a BOP TH400.
My my question is what would be the cheapest and easiest way to swap in and make big power :
1. 5.3 /6.0 with Lsa supercharger
2. 5.3/6.0 with turbo (on3 7876?)
other then the fuel system and the Sc itself what is needed for the lsa?
was the LS TO BOP TH400 problem ever definitively rectified ? (Adapter plate , swap bellhousings)
what what would you go about FUEL INJECTION SITH THESE SETUPS (the Holley efi system seems expensive).
I guess thata enoigh questions to keep to keep you busy for a while
car will be weekend warrior and something scary as **** on the street that can handle Car had an open 10 bolt for no (will change in the future) I want to change as little as possible in order to get it going for the time being

Hey OP, I am in the midst of doing a swap to my '68 Lemans. It has been placed on the back burner many times but hopefully I will get it tuned this summer. My setup is simple. 5.3/4l60e with custom wiring harness. GT45 $220 turbo off Ebay and 2" piping to feed it. 60lb injectors fed by a Bosch 044 pump and the original Lemans tank modified for fuel injection duty. I went with a Corvette LS6 cam and Intake as well as the front accessory drive. It runs strong now off boost, am I am currently tinkering with HPtuners and a 3bar map for the current Speed Density tune.
Can't help much with the trans question except to suggest you pony up the dough and get a 4l80e trans with the engine.
The LSA swap is the reason my Lemans is not done. My '71 Chevelle is undergoing that swap now. I used an LY6 motor with rectangular heads and grabbed an LSA supercharger off CL for $380. Accoriding to my spreadsheet I am already in it for $3k and I still need a few more parts. I presently have all the tensioners, ZL1 lid, fuel rail, injectors, belts, CTS-V crank pulley, heat exchanger, pump, Corvette LS3 waterpump...and the list just keeps on growing. I did opt for a smaller Lingenfelter pulley though. All this is backed by a stock 4l80e with shift kit and Circle D stall.
