What the hell is this guy talking about?

Re: What??
 

4.3? i donno could be just another crazy, could be a guy that knows his stuff but has trouble explaining.

Re: What??
 

4.3...I understood the geezer perfectly

Re: What??
 

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.

Re: What??
 

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.:lol:

Re: What??
 

Not bad for a starter project.

Re: What??
 

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

Re: What??
 

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

:haha::haha:

Still a nice truck though.

Re: What??
 

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

Re: What??
 

lol...please do I want pics :metal:

Re: What??
 

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.

Re: What??
 

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?

Re: What??
 

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

Re: What??
 

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

Re: What??
 

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.

Re: What??
 

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

Re: What??
 

I emailed him....

Re: What??
 

Dude, you should post your email and the conversation that ensues?

Re: What??
 

I will...

Re: What??
 

Get an address or phone number. I'll drive by and take a pic of the mysterious engine.
