One wire lock-up, 4 spd automatic w overdrive into A-body.

I contacted Precision Torque Converters this morning. They sent me a return UPS tag, and it is on it's way back for what I hope is the final time. Once we get this sorted out, anyone will be able to call them up and order a proper fitting converter for this bellhousing conversion. They really are great people to work with. It's tough to get it right the first time when all the parts aren't here for measurement and test fitting. I hope I got my measurements right. If it doesn't fit this time, it will be on me. Most all of the previous swaps using the plates have simply adapted the Chevy torque converters using the spacer plates. I am blazing ne ground by using a GM/Mopar hybrid with the 4 mounting lugs vs GM's 3 mounting lugs.

My engine block is fresh out of the hot tank at the machine shop and the assembled 408" short block should be ready to pick up when the converter gets back. I've assembled motors that turned out fine before, but just don't have the time and inclination to tackle this one. The ported Eddies are sitting in boxes on my bench waiting for that day, and a Hughes recommended cam, HER2836-ALN10, with 1.6 to one rockers should make a sweet hot street combo. (see specs below)

In the meanwhile, I ordered a pair of 1" front torsion bars and some LCA stiffening plates from Firm Feel. I have the small block bars in there now and they were ok when it had the slant 6 & 904, but they are too soft with the 5.9 & 727.

The upside of these little delays is that progress is being made, and I get to enjoy my convertible for a few more weeks in this nice weather we've been having.
