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.

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

rcflyer1234 · 07-27-2011, 01:04 AM

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.

Has anyone called this guy? I live in South Austin. I may have to see this one of a kind engine for myself;-)

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

67_SS396 · 07-28-2011, 11:11 AM

The 229 has a bore/stroke the same as a 305 whereas the 4.3 has a bore/stroke the same as a 350. 305 parts are interchangable with the 229 and 350 parts are interchangeable with a 4.3.

good to know thanks
I had always just heard and compared it to a V8 with two cylinders removed
