I've got an 86 monte carlo sport coupe. Its got a 4.3 liter V6 with an automatic transmission. I'm turning it into a race car, which will have a 350 with a 3 speed manual transmission.

I know the bellhousing pattern on the 4.3 liter is supposed to be the same as the 5.7 liter 350. When I went to bolt the 350 bell housing up to the 4.3 liter engine the starter was interfearing. The bellhousing has a provision for the starter, but it didn't match up with the starter on the 4.3 liter.

My question is,

1. Does a 4.3 Liter engine use a different style starter than a 350?

2. Does an automatic transmission require a different starter than a manual?

I'm trying to figure out where my missing link is.

 

This is what my current bellhousing looks like.

 

Stock car racing are we?Don't know what's interfering here,but you can bolt a 350 starter to the 4.3 if need be.

Haven't seen you on the stompers site in a while,have you left us?

 

So what you're saying is that starters are different for automatics than they are for manuals right?

Yea, I'm switching sports for a while. Couldn't pay for the gas to tow my mud racer 2 hours every time I wanted to race.

I see you're from Springfield, whats your name?

 

Does Big Red ring a bell?

Not sure.but I do know that if you've got a starter that jives with that bellhousing,it'll bolt to the 4.3 just the same as a 350.

 

Oh yea, I thought you lived in Brighton.

I've done some research and here is what I've found. My bellhousing is casting number 3899621. Identical to this.

Now, that says its for an 11 inch clutch. I've got a stock 10.5 inch clutch. Will this bellhousing still work, or do I need a different one?

If it WILL Work, what kind of starter do I need to get for a 350 that will work with the 10.5 inch clutch and this bellhousing?

 

What size flywheel/flexplate are you using? The problems usually begin when you start playing mix-n-match between 153 tooth flywheel/flexplate applications (pass. car stuff, standard duty parts) and larger 168 tooth ones (typically truck stuff/heavy duty applications).

4.3s could be had with either size flexplate/flywheel just as 5.7s could. To my knowlege the starters will physically interchange between a 5.7 or 4.3 with the same size flexplate/flywheel (although I don't think the 4.3 starters are as heavy duty as the V8 units).
