4.3 in a 64 with powerglide
Posted by: Raycr ()
Date: February 12, 2017 07:47AM

The father-in-law and I have been researching the ins and outs of this swap. We've trolled all over this forum and found GREAT knowledge and info. We've checked out about every post by Damian )Lostbooger), as our build will be simular, and many others. The parts list is just about finished and sources found. I have yet to check out the articles on adding a cooler to the EM PG. I checked and the block casting on the 4.3 is for an 85 model with the 2 piece main seal and so far the seal numbers I found are for the 1 piece, just a bit more looking, I know.
This isn't going to be a quick project and doesn't need to be. Dad had a stroke back last February and this will be a therapy as well as getting him an automatic car to drive.

Thanks for all the help you guys never knew you gave us!

Looks like I need to use photobucket or similar service to share pictures, I'll work on that too.

Thanks,

Raycr

Sounds like a fun project! The early 4.3 is easy to mod for reverse rotation and should fit-in nicely.

You don't really need to use a service like photobucket unless you want to. I post low-resolution shots directly from my camera's SD card to CCF. If I've taken a picture with my phone, I email it to myself (reduced to 10%) and then post the reduced image directly to CCF. In almost 20,000 posts, I've never used a 3rd party service.

From what all we've found and compared to some of the other projects I've gotten my self into, it looks pretty strait forward.

I'm still debating the merits of flipping the pistons for rev rot. The 4.3 ran well as it was in a pickup and we weren't looking to rebuild it. It shouldn't have a hard life in the 64 either, just a cruiser.

As for pictures, When I click on the pic icon, a line for a URL is brought up. I don't find a place to directly upload a pic. Don't have ant but pre V pick yet anyhow.

Note to self: The 4.3 turns the wrong direction if you're planning to bolt it to a Corvair PG and install the engine in the rear. Rev-Rot is a must, not an option.

Craig replies: Click on the blue "Attach a file". Then "Browse" through your PC until you find your picture, select it, then click "attach". Note that you're limited to three pictures per post and the pictures have to be smaller than 500k I usually post 100k pictures.

Here's a picture of my rev-rot V8 and Corvair transaxle:

Any 4.3 that does not have a balance shaft can be converted to reverse rotation.
The later model tbi (late 80's through about 1995) engines are very good candidates as they have the hydraulic roller cam but do not have the balance shaft. The late "Vortec" heads are are very low cost bolt on power enhancement that can be done with a bolt pattern redrill for the intake manifold.

The number for the front seal is 17760.
Two piece rear seal for rev rotation is 17720.
Numbers are Felpro.

Corvair FC's [ pickups and vans ] used a cooler..

Directions are here to mod a car front pump cover to use an external cooler.


IIRC drill / tap one hole / plug one passage...add cooler!

When reversing the 4.3 the rods are switched from left to right side of the engine They can not rotated 180 degrees in the cylinder, connecting rods are offset I just did this on an 86 and it runs great. It has an aluminum intake with the factory quadrajet.

Hey guys, long time no talk.

What I believe he is referring to with flipping the pistons is the offset of the rod on the pistons to accommodate for the reverse rotation. It would help the engine run a little smoother if you did, however having the pistons in that offset is an old racing trick some people used to gain a little more power. I left mine in that configuration, though I have not driven the car many miles due to life getting in the way so I am unable to speak about the longevity.

Good luck!

For pin offset change, (given that you are using flat-top pistons) the rod stays in the same place in the motor, just press the pin out, turn the piston 180 degrees and press it back in again. Then put it back in the same hole. In the 4.3 the piston and the rod are the same on all cylinders. The rods are different from the V8, but all six are the same.

Thanks guys! We ordered up a bunch of parts this weekend and getting a bit exited to dive in. Getting the parts for the rev rot conversion, cam, gear set and seals. I didn't think about seals being directional till I read the posts here.

So there is still a bit of a debate on what to do with flipping the pistons. Flip the piston on the rod flip the whole works to the other bank or run it as is.

Thanks

Late model 4.3's can be reverse rotated, if you really want to...

Well folks we got the first parts order in today. It looks like I screwed up on the cam. The cam I ordered was a Clevite 229 1882. It looks like it's a roller cam and we need a flat lifter cam. Is the Melling 22120 cam the flat tappet cam? Hopefully I can return this one. I ordered the cam and lifters from the same place at the same time and nobody caught it.

I am using the Melling flat tappet cam and gear set but I can not remember the part number. Sorry.

Sounds like you are on your way. What are you planning for the radiator?

Looks like both cam numbers are for roller lifters. The place I got the first cam from can't find a flat tappet cam.. Soo, if anyone happens to have a number for a flat tappet, non balance shaft, reverse rotation cam, PLEASE let me know!
