Post S-10 SBC Conversion

I've got an '84 S-10, pretty beat up truck but solid, For kicks I may put the 353 in it. (750 holley, weiand stealth, stock heads, 9.25:1 pistons, comp cams 275de) with a stock th350. The engine is for my '69 camaro but while that get rebuilt I wanna have some fun with the truck.

the truck has a 2.8 v6 now with standard brakes, p/s, standard 4 speed. Now besides new mounts and new driveshaft, what else do I need to do? can anyone who has done it before walk me through it?

you may need room for your transmisson to fit i have never done this but have talked to a few people who have . is yours a short bed or long bed. if its the long bed or extended cab i dont think youll have a problem with the firewall but if its a shorty you may have to get the sledge out and tap on it some. depending on what trans you use also. are you going with a th350,th400,powerglide if so you have to cut a little hole for the linkage . also you will have to get an electric fan set up depending on the truck you use (corret me if im wrong guys) other than that have fun <img src="graemlins/evil.gif" border="0" alt="[evil]" />

pre 88 trucks you have to beat the weld lip on the lower firewall just above where the belhousing is to get clearance, also have to use the small flywheel or use a mini starter to clear the frame,, you can use late 70's early 80's malibu 305 exhaust manifolds, or use hedman headers, motor mount plate can be made from two pieces if 5/16" plate about 5"x 8", run dual exhaust down the same side,to avoid fuel tank problems.

I have normal a fly wheel, and a normal starter on my '82 S-10 with a 350, what am I missing. After looking at other peoples converions, my engine does sit lower than others, maybe thats the difference. I don't know. And the tranny's fit fine as well. I did how ever have to have a new tranny cross member fabricated, the original is in the wrong place. I'll have to do another one too because I just got a 700R4 for the truck. My one problem was with the distributor, I couldn't fit HEI because there was now room (the firewall is too close) and I didn't want to beat the firewall in. So I had to buy a Mallory Uni-lite ignition. Good luck on the conversion, its not that difficult.

I did the swap in my '84 4x4 a few years ago. You may not need a new driveshaft, just new engine mounts. Depends how far you move the engine back when you do it. Check out <a href="http://www.jagsthatrun.com" target="_blank">www.jagsthatrun.com</a> for mounts. Your current transmission won't bolt up to a SBC, either. I tried '76 Malibu manifolds and couldn't get them to clear the frame. I guess this depends on how low you mount the engine.

More then one way to skin a cat, I suppose.

I was planning on using an S-10 bellhousing for my streetrod...I wanted the hydraulic cylinder mounting pad the S-10 has...BUT the S-10 has a different clocking of bolts and the bellhousing was off by about thirty degrees my starter would have been on the bottom and my shifter would have been on top...big expense for bad news. So point I am nakig is if you go V-8 better get bellhousing to match v-8 the S-10 was off.
