I've made a couple of posts before. I went through a bad fire that killed my 1970 Olds 442. Without going into detail it had 35K and took 1st place at the Silverado Concours d'Elagance Mare Island, CA. in 2001. I had temporarily purchased a 65 442 from a place in NC but found out it did not have the original engine in it so that got canceled. Per the OCA 442 advisor I found the car pictured here that was on ebay. It's a CA. (Fremont) car and a Chevy guy did much of the restoration work and I will "correct" what needs to be done. But I like doing the detail stuff. It's got the 330 cid motor, Edlebrook carb on a slight highrise manifold and upgraded ignition system. The motor has been gone through and has a mild cam and it sounds like it must have at least 10.5 to 1 pistons. I don't know the details but it's not stock and it doesn't sound stock. It has dual exhausts. You see, I took my drivers test in a car just like this and it was stolen in 1968 and we never got it back. I still have the keys to that car. The reason I have this car is that if I got another 70 442 I would always compare it to the one I had. With this car it is like getting the stolen one back. They fellow I got the car from just liked doing cars but he said he's a Chevy man. He found the 442 insignias and stuck them on it. I have the protectoplate for this car and it was purchased by a person in WestminsterCA. in Sept. of 1965. It has no rust and the original undercoating. Other than detailing it I want put the 442 tips on the dual exhausts (and replace those as the left pipe for some reason is touching the differential and I'd rather just start over on them), and look at the 4 speed 200r4 transmission or TH 350. I do not want to get into messing with the rear differential ratios. He did send some other parts with the car. I do have the original carb but it's not in good shape but maybe restorable but it appears to be popular to replace it with the Edlebrook.

 

Looks like a real nice car - congrats!
The 200r4 is a direct bolt-in, just some linkage fabrication and electrical connections.
Just make sure you get a good one - and adjust the TV cable correctly.
Good luck!

 

Not quite, but almost. Since the TH400 was not offered in the 1965 cars, you'll need to drill the frame rails for the crossmember location with a 200-4R. Not a big deal, but just slightly more work than a total bolt-in. On the 67-up cars the holes for the TH400 are already there (the 200-4R uses the same crossmember location as the TH400).

Because the crossmember is relocated, the e-brake cables change (they hang off the crossmember and thus are affected by crossmember location). Get the front and intermediate cables from a 1967 442 with TH400. Some people have been able to make the original cables work, but it can be marginal. I'd err on the side of using the factory cable lengths.

 

I did a write up here with photos on this 200r4 swap into a 65 last year. It's a pretty easy swap drive shaft same length, cross member works just move it back and drill new holes and I use some 1/4" thick spacers between it and the frame, I used the original Ebake cables just had to fab a couple extra hooks for the cables to spread them out a little, it works better now than it did stock, if you have a floor shift Shift Works makes a conversion that works perfect. I found that the 200r4 works perfect if you have it converted to a non-lockup converter, all the aftermarket kits work just marginally "at least in the mountains". I love mine the OD works perfect with my 3:90 gear.
Good luck with your car it looks just like mine also built in the Fremont plant.
