Yeah I was kinda thinking this as well but that makes it sound like there is a V-8 in it with the back two cylinders empty or something.
Terrible explanation.

Maybe you could use the other 2 cylinders for an onboard compressor.......
A smith compressor uses a ford 302 with one bank to run and one bank as a compressor.

4.3...I understood the geezer perfectly

gchemist · 07-27-2011, 12:45 AM

Not bad for a starter project.

INSIDIOUS '86 · 07-27-2011, 12:52 AM

call him an ask him if he can unblock the cylinders and throw in two more pistons for you HAHA

GM must have ran out of 4.3 blocks when that truck was built so they just used a 350 block and modified it.

Still a nice truck though.

The 4.3 has the same bore/stroke as a 350. I remember when they first came out all the talk about it being just like a 350 with the rear two cylinders cut off.

I worked with a guy that swore up and down that was how GM made these.Dude was always right so you couldn't correct him.You know the type.

motornut · 07-28-2011, 10:41 AM

thought the 229 was with two removed......never heard or seen this
took out a 229 put in a 350 quite ez
can't just be loose floating parts?

67_SS396 · 07-28-2011, 10:55 AM

A 4-3 is a v6 block, simple as that, there are not any "open" cylinders.

The '85-up 4.3L V-6 has the same bore and stroke as a 350 V-8 (4.000x3.480), and takes the same pistons, cam bearings, main bearings, valvetrain parts, timing cover, oil pump, and front dress.

motornut · 07-28-2011, 11:06 AM

lookin it up the 229 stopped and changed to 262? in 85
mine was 81
sounds like the earlier one had even more in common, in parts

jrcaprai · 07-28-2011, 11:59 AM

I emailed him....
