Nice rod7515 with a 3.08 chimed in ! And confirmed my worry that gear would cause some issues. And the BTO cross member fit so well in my 1980 even accommodating the exhaust the goes from driver side and crosses to passenger side I was shocked . Matter of fact I am removing that pipe because the BTO cross member allows for a straight shot from header to over axle pipe allowing me to eliminate that one curved pipe.

If some had an issue my guess would be he may have had a 80-82 cross for an earlier model that would cause problems or an earlier cross trying to fit it on a 80-82. I until today have never herd of a bto cross not fitting just right it is possible I guess it was manufactured off.

True Rod, so true! When I bought mine this year I'm sure some people I know questioned my sanity. LOL

Adams' Apple said: I haven't actually done a swap myself, but I have build several 700s for members here, and several for local club members. The last one for a feller here used a factory crossmember from a '77(I think) to install in his '81, and was a bolt in deal, other than having to elongate the mount bolt holes a wee bit. Of course, he had to shorten the driveshaft, and set up the TV cable linkage. I think he took it to a muffler shop afterwards to finish the exhaust. I did one a few months ago for a club member that bought a Bowtie xmember, brackets, etc., and he had a lot of issues with getting everything to fit correctly, so...who knows? Then again, this particular guy is a perfectionist.
I did do a swap many years ago from a 350 to a 700, but that was on an '82....that should have had a 700 in it to start with....someone had swapped it way back when...when nobody knew how to fix a 700.... LOL

interesting, at least I dont have to worry about the exhaust with side mount pipes Tongue

The side pipes are out of the way, not an issue with the trans.

By the way Jason, I was looking at your pictures of your rebuild, you've done a ton of work on the car, nice job.

I did my 700R4 a couple of years back now. One of the best moves I made. With 3.73 gears in the Lukester, the low first gear is insane and costly for my tires. At 70 MPH, I'm turning about 2300 RPM as opposed to about 3400 RPM with the TH350.

Shortened my driveshaft 3" and wend tithe the BT Overdrives crossmember - fit like a glove!! Well worth the conversion cost!!

If you want the OD trans, I think a 700R4 is the way to go!! Thumbs Up

This is my decision. I have talked to a very reputable, local transmission person (who happens to be in the process of restoring two sharks), so he is very aware of a C3. Because I don't do very much freeway driving, I have decide to go with a set of 3.08 gears. It was calculated that while dring at 65mph, I should be around 2550 rpm's (compared to my current 3200 rpm's). I can buy a set of 'Yukon' gears, and the other items for $440. The mechanic has not gotten back to me yet with a labor fee (this same guy rebuilds differentials too). I am going this route because this is the least expensive and I have much more to do (radiator, A/C, brakes and finish chasing that oil useage issue). If I had gone with a different transmission, I had decided (for me) I would have gone with the 200.

Glad to see you have made a decision on which direction you are heading. My 74 has a TH400 with 3:08 gears. I have no issues driving it on highways and I think you will find there are a lot of vettes that have this gearing with an automatic. Are you going to get another carrier to do your gear change or are you removing your old gears and replacing them with the new gears using your current carrier. I only ask this because you can probably find a set of 3:08 gears and then keep your old gears in case you would have to go back to them. This is what I did with my 3:08 gears although I dont think I will ever be going back to them so they sit here on the floor going to waste. To bad your not closer. If you want an actual RPM reading in drive at different MPH I can give you what mine is.
Best of luck with your conversion.
Rodney
