Bowtie Overdrive Transmount arrived, problem
This forum wasn't up when I had the question this morning, so I posted at the other place. I'm posting it again here so everyone here can know what's going on.

I remembered later that when I did the 700R4 conversion, I used my Turbo 350 tailpiece so that I could keep my 79 Vette driveshaft/yoke.

I got my Bowtie Overdrive Crossmember yesterday, and of course I went to intstall it immediately. First I weighed it. It's 18lbs, the stock crossmember is about 23lbs. Only a 5lb savings, but it looks much better. My early 700R4 has two trans mount positions. I had been using the rearmost with my stock crossmember. The Bowtie crossmember wants to use the front trans mount and there is major interference between the crossmember and the rear mount. What's up with that. Do later 700R4s not have the rear mount? What should I do. Find a later tailpiece. Order the 80 Crossmember? Help!

Yeah, some pics would be great...
As you know the 80-82's have the cross member where you can only run the exhaust down the pass side.. Does not look good in my opinion. Also another member on here cut his driver side crossmember. Looks good.
Just trying to play out my options. I think this cross member has enough arch in that you can run the pipes under with no problem.
I see you got rid of that pesky spare tire....
Thanks,

[QUOTE=Bee Jay;1573212891]yep, save 60lbs getting rid of that never used sucker. Lost another 35lbs going to the aluminum batwing. That's 95 lbs I was allowed to gain thru non-healthy eating and no exercise. Looking for weight savings in that heavy *** exhaust system now.

And the composite spring too right? These are some of the things I'm considering. How about the factory bumpers, not the covers. How much do you think those weigh? (Sorry for the hi-jack)

I did that too. The factory rear bumper is gone and I have a composite rear spring. Check my signature for the bumper weight loss mods. The car has gone from 3600lbs down to 3200lbs so far.

The BowTie crossmember is designed to use the mounting just behind the pan. I used an '82 Corvette tailhousing on mine and had to make some mods because a C4 700R4 does not have those holes drilled and tapped. BowTie says they do it that way so you can use any 700R4taillhousing.

i noticed the same thing when i added the h pipe to my car.....let me ask about the order you did it in and what you noticed....did you add the x pipe after the H pipe was installed? and is this when you noticed the difference in the resonance? i noticed the drop in the "drone" or resonance with the H pipe and an increase in torque also. bob
