I have the same Frame. It was originally for a 550. The biggest difference is that the inside 2 Exhaust Ports won't clear. BUT, a good Welder can fix that for you, by simply widening the 2 Down Tubes. (right ChopperDad?!) They can also add you alittle more rake while they're at it. The Engine Mounts were already on mine for a 750, thanks to the Previous Owner. Also easy enough to Fab up. I can take some measurements for you tommarrow and Post them. The Engine itself actually fit in there ok, it wasn't until we went to put the Exhaust Pipes on that we saw the real difference. I dunno if you Weld, or know a good Welder, but it really is a easy fix. May-be 73Coupe can tell you more about Frame Mods. He's my locale Go-To ChopperHed. Roadkill is also a good Savior guy. He might even know those measurements right off the top of his head. He really knows his stuff about Saviors.
