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.
yes and no. I beleive that the bolt pattern on the block is the same, but the opening and depth of the Tranny bellhousings are different. Basically if you are using a 3 Speed manual you will need a starter to fit a 350/3 Speed manual car. HTH Chris

I am just wondering why you are bolting the three speed to the 4.3? Are you just bolting it up so you can bolt the 350 to it and line up the engine mounts? If so I could take a pic of my frame out here from my parts car and you could see which set of holes to mount the mounts to.
I think the starters are different from a manual to an auto.
Let me know, Randy

I'm wanting to bolt it up to the 4.3 so I can get all the kinks worked out, Bleading the hydraulic throwout bearing, shift linkage, etc. Before my race motor is ready to drop in. If I'm going to tear something up, I would much rather it be the 4.3 than my $5000 race motor.
