Performance 4.3L
I own a 94 s10 ss and have a overheating problem due to a suspected cracked head. The motor has 250k on it and I have been adivesed to repace the motor if I want to keep the truck. I am going to bite the bullet and repace the motor. I want some more ponies then I have now and was thinking 350 swap. My mechanic says he has done so many swaps that he wont do one a gain cuzz they are a pain in the ass.
 He suggested that I look up some performance 4.3 that I could drop in. I have seached a bit on the net but dont know what will fit the best. Please give me some links or info on proformance motors which will be a hassle free swap for my baby. Thx

I was looking around awhile ago, and i found that www.s10forums.com has a good overview on what it takes to swap a v8 small block, and even a basic rundown on putting a big block in an s10 (that looks like an experience), but it gives how to instructions, oh and what exactly is a SS s10 entiled to, i have see a few of them advertised, but i don't know what qualifies them as a SS
Hope i help a little

I think an ss, and dont quote me, has a roll pan, painted front grill, fully loaded, and a sport suspension whatever that is. Maybe the rearend is posi I am not sure. Thats all I know.

Re: Performance 4.3L
If you are looking to do a swap with just another 4.3 check engine codes. Depending on the year there were different motors with the same liter. For example in 94 there was a z code motor and a w code motor. the w is a highperformance motor compared to the z code.

Re: Performance 4.3L
ok... when you do find out if your motor is shot or not .... and if it is ...
if you replace with a 4.3 get a 96+ ... the earlier ones you cant get any bolt on superchargers ...  and if anyone knows of a bolt on for a 94 4.3 CPI ... lemme know
