I figured as such. Any truth to them saying that these "Early Vortec" heads from 1995 yield a 10% BETTER AIRFLOW than the other years heads of the 4.3 (I am assuming 91-ish to 1994?) - That is a sentence in the big, pages long FAQ about VIN W and VIN Z engines...and Tonawanda and Romulus interchangeability and etc on s-10forums.com (the one with the article about the Big 3 upgrade.) I have seriously thought of taking my 4.3 to a machine shop. Maybe for a bore and stroke..
or, just to see what on earth the inside looks like, then replace/fix/mill from there. If there is no hole in the head, or warpage. In which case, new head.. i don't know. My thoughts fell apart mid-paragraph. Let me separate them.
How about injection off a VIN Z of comparable year? (ECM issues, right?) Or.. Have i hears that some use the fuel injection of a GM 3400? .. simply asking if there is any way to rig up something different, if any S-10 modders have spent weekends in yards or online looking for parts.
I hear the spiders are VERY problematic. And a member here sells.. but only for 96 and up.
Just some thoughts here..
Or instead of turning it into a Franken-Blazer just to make it work like it's supposed to, you could sell it and buy something that does work like it's supposed to.
Ahhh, you missed it. This truck has high sentimental value. It's not for sale.
Some may look at it and scratch their head, but I see a vehicle with a remanufactured drivetrain and a rust lesson.
