1993 Chev 1500 4.3Z

I bought this truck new and it now has 266+K on it and the engine is running very rough when it runs at all. I know cylinder 2 has 60 lbs and the rest are at 120-125.

I would like to swap out the engine for another 4.3 from another year if that is possible. What are my options?

87 to 95 should bolt right in and work correctly with the TBI. you can probably find one from an S10 or astro van easier then one from a fullsize

thanks for that info. Does it have to be a "Z" engine or will the "W" work with the computer?

some W engines use a balance shaft so the Z intake may not fit

the holy grail of 4.3 info!! - S-10 Forum is some decent 4.3L info.

I don't recall what year the 4.3L V6 got a balance shaft. But basically you want to replace like w/like as closely as needed. By that I mean don't go '96-up, else the intake surely will not fit and there's no way to make it fit.

And if you go back to '85, the engine had a 2-piece rear main seal and in '85-'86 the cam was a flat tappet. But '87 through '94 engines should work even though the cam specs weren't identical; the amount of vacuum they made was sufficient for the stock ECM to handle. Edelbrock sells a TBI performance intake for those years, p/n 3713.

Good luck.

My local wrecking yard has a few reasonably low mileage engines (93-95) so I was going to get the complete engine so it comes with intake on it and I hope this isn't an issue then.

Thanks for the replies.
