don't buy anything besides that main girdle from DSS..I spent almost $2k over there and got treated like I was wasting their time (both when in the store and over the phone (over the coarse of about a month))..not getting told what I will need to support what I bought so I had to spend more money than Tom (the owner) said I was going to..had to de-burr the main bearings and the crankshaft myself even though I paid $200 to have polished and balanced..and tolerances were larger than I would've preferred on almost everything (bought full 331 stroker kit).......I've been meaning to let people know about them and haven't........the girdle is nice though....there's plenty of good speed shops out there and I was about 85% unimpressed with DSS
