Help me out here guys,

I need to get a new engine for my '72 Blazer and I have a line on two. One in a 1987 5.7l IROC TPI with 126k. This one is missing its' MAF sensor,

The other is a 1997 5.7L TBI with Vortec heads that has about 80k. Both are not too bad for price.

Which would you choose? I really want to go fuel injection!

Also do you know where I would be able to get the PROM chips reprogramed around here in Vancouver? And I would also need an '87 -91 Blazer/Jimmy gas tank.

Thanks for your help,

Rod

Have you heard anything about not being able to find a flywheel that will fit match up with a SM465 if I use the Vortec?

oso tell me do they come with the computer? I'mlooking for ae engine at this time too. so if you don't want them both,let me know how much the person wants for the other.no you don't need the fuel tank, just an electric fuel pump that pushes at least 15p.s.i like a ford fuel pump.also the wireing harness and oil pressure light.

He'll need more than 15 psi for either of those motors. The throttle body injection uses relatively low pressure but both motors he's looking at are Tuned port injection and will require high pressure pumps.

I know that they needed a high voloum fuel pump but I didn't think it was that high.
do you know that for a fact?
