Re: 4.3 vortec to 5.7 vortec
I was almost ready to post up most of the same idea, I want to drop in the 5.7 and throw the 4.3 away, I want to know if the wireing is the same, exhaust is not really an issue (you can deal with that ) but if th wireing will plug right into the top of the engine that would be an easy swap.
I am working on a 98 4dr blazer, rad will be moved forward, and exhaust will be done at a muffler shop, motor mount can be moved, but can the wireing plug right into the 5.7 ?
