4.3 installation - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Free88 · 10-16-2009, 09:17 PM

Does anyone have a picture of a 73-87 chevy with a 4.3 installed. Putting one in a daily driver and need photos to see where the motor mounts mount on the frame, as well as to where things hook up, especially electrical. Oh ya it is an 87 4.3 into a 86 frame. Thanks

everything is exactly the same as a sbc v8 except its missing 2 cylinders. all the brackets and mount interchange its basically a direct bolt in swap

ive done the swap and it was direct bolt in to a small block that was on an 86 custom deluxe

Free88 · 10-17-2009, 12:00 AM

So it bolts right up to V8 mounts that are in there. Thanks guys.

you will need the radiator shroud for the v6 as its alot wider to make up for lost space.. all my old pics of the v6 truck were lost during a computer crash.. at least of the engine

Thanks. Will do some pics when I start the install.

I thought the motor mounts had to be moved ? The motors mounts are the same, but they bolt to a different place on the crossmember. That's how it is on 88-98 trucks anyway.

I know the mounts are different on a 4X4. Frame and motor. Don't know about a 2 wheel drive.
