it is easy to get carried away... I would personally just get a SBC intake that has provisions for Multi port. I have converted a truck from vortec to TBI. It was a major undertaking. Swapped whole dash & interior harness plus engine harness. LS swap will just nickle and dime you to death IMO. Brackets can be swapped in a day...
Great info, thanks. Now to find an early 90s caprice cop car.....

I've definitely considered the MPFI intake option. It seems like the Holley single plane is the only real option still in production? I know the Edelbrock 3505 (OEM throttle body bolts on directly) is long out of production. And there was a GM/Mercruiser marine MPFI option at one time? Any others?
