Also not trying to hijack the thread but I called Randy's yesterday to get some info about sure grip units for my 8 1/4 & the guy made me feel like I was an idiot for even wanting to use an 8 1/4. I am building a mild 350 +/- hp 360 for my '65 Barracuda & unfortunately just don't want to play all the over-priced 8 3/4 games. I would rather put money elsewhere. It is $500+ just to find an a-body 8 3/4 than start adding in sure grip & gear ratio prices, it can easily hit $1000 or more. It was actually funny how much guys were asking for 8 3/4 chunks at the Nats this weekend, of course very few of them were selling so....
The 8 1/4 should be more than strong enough for a street driven cruiser with the hp I am hoping for. The guy from Randy's also told me that he did not know where their units were made & chuckled as he stated that he didn't think any of them are made in USA anymore.
Am I wasting my time with this rear end? Do I really need a suregrip? $450 for the only unit they sell seems like too much money to just be able to lay down 2 tracks of rubber once in a while, especially not knowing where it is made.
