Ron the trans was built by Pat @ SMR in Ontario, full reverse manual with a 3500 stall by him also. I gave him the specs for the build and cam and he built the converter to match, he says it will drive like a stock converter but flash when I hit it. 3.55's in an 8 3/4 for now until I can afford a Dana. Hopefully the nickle coating holds up, it won't see any inclement weather so it should be ok. Similar combo and use as your 63. Pretty much going after the mid 60's super stock/ street brawler look.
