Curious if anyone could give me a price range for the swap? It's possible I may be getting a motor from my friend. He has a 5.7L 350, which was rebuilt so its "bored out" to get clean cylinder walls again, so that adds 5 cubic inches or so makin it a 355, doesnt really increase the power, just freshin's it up. he has stock heads, high rise intake, regular size carb, basically he has a mild 355, almost stock.. after doing the heads/headers I was thinking about putting in this supercharger that I found locally that will work with the small blocks.. ( http://vancouver.craigslist.org/pts/262671121.html ) what would I need to do to my blazer? I was doing some research and it seems I would need to do the following:

Engine
Engine mounts
Headers
Electric fans
Harness and computer.

I can get the engine for pretty cheap, and im pretty sure I can find everything else for cheap and can I get the harness and computer from like a v8 truck or something? I wouldn't be doing this swap obviously.. so let me know what you guys think is possible and how much I would be looking at ballpark figure.. thanks.

 

umm, i'm pretty sure you can get the motor mounts and headers in a package deal. i've been looking at pretty much the same stuff since buying an ls1 to put in a 99 s10. and i'm pretty sure you can find a cpu from a wrecked truck at a graveyard.

 

Anyone else that can give input?

www.jagsthatrun.com they have everything you will need to do the swap. they also have a manual on how to do the swap.

 

Yeah, I just want more power.. what can I do to the 4.3L that will be cheaper but ill be able to get more out of it?

 

yah i have a 5.7L , 350 , in my blazer if i were you when you get motor getthe numbers of the back of the block and then you will be able to know exactly what you neeed

 

5.7
What all did you need to do? was it a back yard job or did ya take it some place else and about how much did it run?

 

I have read countless threads on here using the search funtion and have seen prices ranging from $1500 - 6000! If anyone can help me, I wanna know what I will need to do in order to get a 350 in my blazer, and how much it will end up costing. Thanks!

 

Here's this eBay auction. It's for mounts and headers.
