my jimmy has a 4.3 vortec can anyone tell me if a 4.3 vortec out of a 95 chev half ton will work

 

If it is the Same VIN code (W or Z) should work just fine just use your TBI unit. To be safe treat it like a long block and swap over all your existing Intake system and accessories.

 

that's kinda not nessasary.

there isn't any "Z" code in the 2nd gen trucks. but he is right, so long as the 8th digit is the same, it souldn't be a problem. but like he mentioned, you're more than likely going to need to change over all of your drive accessories on the front-including the brackets.

 

This motor comes complete(basicly everything was unpluged from the truck and pulled out with the motor.) with wireing harness,computer under the hood fuse pannel,starter and altinator, manifolds .. the only thing that looks different is the fuel injection set up. my 1st 4x4 dnt kno much about them.

 

*Moving to '2nd Gen Tech'. Please pay attention to what section you post in*

 

oh, so the p/u's engine is a Z code (TBI) then, not a W code (CPI) like in your truck.

looks like you've got an issue on your hands. the only way you're gonna have that new engine run in your Blazer, is to swap the top end from each engine.

that means you need to remove the heads & intake from your Blazer's engine, and swap it with what is on the "new" engine. which is quite a bit of work, for a used engine.

and no, you can't just swap the intake systems. the head-to-intake angles are different between the Z code & W code engines.



mind telling us why you're changing the engine in your truck?

 

i smell gas really bad and theres white smoke comming out of the exhaust and she runs ruff

 

can i use the whole engine if i change the wire harnest and fuse boxes
