    TH2004R is a dual pattern bellhousing, has both Chevy and B-O-P. I have one behind the Pontiac OHC in my 65.

    The 200 would be a poor choice for towing. The 700 is just a 4 speed TH350, and it's marginal at best. Regardless, towing in OD is strictly verboten.

    Yes!.... I've been looking at those! Anybody choosing that route should use a pre-87 engine because 87-95 uses a different intake manifold and they are pricey! Best bet for somebody that has gutted a TBI donor car and gotten everything, including ECM and sensors.... Is to get a harness and reflashed chip for your ECM from AffordableEFI (about $450)....
    I thought about trying to organize, modify, and re-use the donor-car harness, but there is just too much complexity to it.....
    Either option requires an extensively different gas tank and fuel pump arrangement.... several hundreds by itself!..... I think eliminating the gas smells will be worth it though......

    I would agree that this is the best choice. The Corvette site has numerous installation threads.

    I have a friend who used a Holley EFI, a few bucks more - also works well.

    The problem with salvaging a system is the cost of replacement parts. Then the salvage price is no so good.

    I did a conversion to a carb on a TPI motor 2 years ago. You need fuel pressure regulator, manifold, distributor and carb. My total cost was just under $500.

    Less than the cost to repair the existing system.

    Depends on your rear end ratio and trailer weight.

    staypuff, thot I'd throw in a comment on how good a TH350 can be. In '88, I had a local tranny shop build me a TH350 specifically for RV towing. Not sure what he did to it but it shifted solid and quick (no slippage at all), even with a little bang if I got on it. It is behind a real torquey 292 and tows a 5,000 lb travel trailer, that's heavy duty work. This was up and over the Cascades and Rockies, over 10,000 foot high passes. It's got 90,000 miles on it, mostly towing and is still in perfect condition, had it recently serviced by the shop that built it. Always ran about 190-200, maybe up to 230 degrees for short distances on mountain passes in 90 degree heat. Cooled right down on the downhill. Rear end ratio is stock 3.36, use two trans coolers.

    As for towing in overdrive (which my TH350 doesn't have), as I understand it (correct me if I'm wrong), the low rpm's don't force enough trans fluid thru it to keep it cool, plus it'll want to shift back and forth cause no highway is completely level (except in my home state of Kansas)(go Jayhawks!!!)

    Found one, I think...

    I think I found the donor, 91 Chevy G20 with 27K. 350 TBI with a 700r4 trans. I am going to take a look at it tonight, owner says I can here it run. For $800 it seems hard to pass up.

    Missed it by that much....

    I was an hour too late to get the power plant out of the van But I was able to source a rebuilt 200r4 lock up today at the swap meet here in Norman, OK. I will pick it up sometime in the next two weeks. Now I just have to figure out how to hook up the shift cable and the PRNDL selector from the column.
