I think 400 is too big for TPI. Don't get me wrong, I love TPI and have 2 running now, but if you rev high or have big cubic inches it gets expensive fast. Now if you built a 350 with TPI that would work well. My '83 K20 I swapped from the stock 350 to a '91 Corvette 350 (aluminum heads, roller cam, hypereutectic pistons...) Mileage went up. Driveability improved. It starts instantly. But it won't outrun a Vortec. It all depends on what you want.
