61 4 door 4.3 v6 PG
Greetings
I noticed nobody here has a 4.3 conversion so I figured Id show off my progress.
The car started off as a basket case as far as So Cal standards go so I figured it would be a good candidate for a conversion.
The rust was minimal except for the rear overhang. The interior was shot. The body was mostly straight.
Ive since rebuilt the front and rear suspension and installed urethane bushings.
Replaced literally everything except the pedal pertaining to the brakes.
Installed aftermarket 15X7 wheels and tires.
The 4.3 conversion was mostly easy. It required me to convert the engine to reverse rotation. I literally got the last bellhousing from Kennedy engineering. Theres other ones out there however. The hardest part was finding the parts. I can supply all the needed part numbers to anybody that request them. I converted a used engine from an 88 s-10 for temporary use especially since the radiator placement is questionable.
The crossmember was easy enough to fabricate from a universal one.
The alternator is just a normal alternator with a reverse rotation fan installed. I used the stock s-10 mount and modified the heck out of it.
So far the radiator is working fine but I havent really been able to put it through the paces since Im currently having a transmission issue not related to the conversion.
Speaking of trans it is a stock PG that I have done absolutely nothing to except change the fluid. I have plans to upgrade in the future.
I have yet to really romp on the car so I cant yet tell you how fast it is.
From what I have driven it there is definitly waaay more power then stock lol.
I have a few vids of the car and the engine I hope you enjoy.
First pic is the engine.
Second is the crossmember mounts to the frame.
Third is the side shot of the car with the 4.3 and the stock springs (this is to show that not too much weight was added)
Im in the car about $3.5k. Most of that was the cost of the parts needed to restore it. Like all projects I still have much more to spend.
The conversion for the most part is easily reverseable.
Any questions feel free to ask.

Hey, that's really nice! Yeah, it'd be nice to get some air flow for that radiator, huh?

So far there is enough airflow. Ive taken it on the highway up to 70mph and it was fine. Ive since done a couple improvements. I still have to build a bottom shroud for it. It is a pretty large radiator with a descent fan. I think it will work long term but only time will tell.

That is really cool. I like it allot.

When my Mom was alive she didnt care for Corvairs lol.
Thanks for the backhanded compliment.
My other car is a 66 Corsa. I refuse to modify that car however. I chose the 4 door EM because I didnt mind modifying it and I really like the looks of it.

I like that you chose a 61 4 door. Its different than the usual LM conversion everyone else does.
and nice looking CORSA!

I am building a LM coupe with 4.3, rear mounted, with a powerglide. I had a bushing made to center the torque converter on the 14 inch 4.3 flex plate. How did you do it? I am not sure this is the best way but I think it will work. I am using a MID bellhousing I located. Any suggestions would be helpfull. My car has factory air but is in rough condition. I have owed it for 29 years but had to wait for retirement to work on it. Thanks in advance for any help. Jerry Casto.

1966 Monza coupe PG. Installing a reversed rotation 4.3. Not a hot rod just a fun project.

Re: 61 4 door 4.3 v6 PG
Aluminum radiator? Does that help with the heat transfer significantly? About 262 cubic inches. The stock Corvair Powerglide transmission is supposed to be pretty solid. What plans do you have for an "upgrade"?
Could this be done with a 4-speed transmission? It would be interesting to combine this with a LM rear suspension conversion, a beefed-up 4-spider gear differential and a Saginaw 4-speed from a 1966 or later Corvair. It would still look stock, but what a sleeper! It looks like a very clean conversion. Congratulations!
Love the yellow Corsa coupe, too!

Re: 61 4 door 4.3 v6 PG
I love it!
Ive had an idea rolling around in my head to build a Corvair with 4.3 conversion instead of the V8. I love how you reversed the cam so you could use the original transmission. It would seem to me to be easier so you wouldnt have to modify as many parts.
I haven't put my ideas into motion bucause of a Mustang project.
I would be interested in knowing all the different parts you used and any other info you have.
