SB 5 Main Halo

SB 5 Main Halo
Here are the specs and a couple pics of my 5 main halos for small block Olds;
1018 Steel
All sides CNC’d
Approx .400 thick
These were test fit on a about a half dozen blocks, a couple of 403’s and the rest 350’s. We found an inconsistency in the alignment of the main saddles, most notably #4 main. Because of that they don’t fit as well there as I would like them to. But with good studs and proper machining these should still offer a stiffening of the main saddles. In addition these will be significantly flatter than the previous J&S halos.
Cost is $365.00 (halo only) plus the ride.

As stated the bolt holes are a bit of a compromise because of the inconsistencies of the main saddles block to block. In order for it to fit everything, the bolt holes are a bit larger than snug.
