Re: Can a 1997 350 vortec go in a 1990 suburban?
It sure can. Like butter. =) Look on the edelbrock web page, go to their port injection. They sell the injection to make a vortec motor work in a TBI truck. You will need new exhaust manifolds, or better yet get shorty headers. Edelbrock has the kit, it works with the stock ECM, and they supply the chip, custom burned to what you have. The Vortec motors are great, from the heads to the roller cam. Check out Crower and Crane for a little bigger cam, nothing huge, but a little goes a long way with those motors.
