454 tbi questions

[MARKDTN]

I looked on car-part.com and in California you can buy a complete '91 up 454 for less than $1000. Add a harness, ECM, and an '87 fuel tank with a new pump and go. Change the hoses to EFI hoses and clamps. With the right exhaust and mounts, it's a bolt-in swap. I put a Corvette Tuned-Port 350 in my '83 K20 and I love it. If you buy a whole engine, everything already goes together. You don't have to worry about port mismatch. You will have a TBI unit and a distributor. If you tried hard enough you could probably get the ECM and harness together with it. The factory TBI harnesses are very simple. I like using as much factory stuff as possible. Parts available in any parts store in the US. Could take to a dealership in a real pinch. You may not be able do that with an aftermarket system.
