Yes it should bolt up, just like the other engine. I have had both in my 5.30 index car with no changes at all. Both were 10.2 deck height. Paul

I have a 565 built with a Dart block and mounting points are the same as my old 468..

Re: ? about dart big m
Still might be a viable option. Ad up what all the stuff new is going to cost and compare that to changing pistons, cams and springs in a race motor. I think it was close to 17K to do this motor and that was a few years ago. With the quality of parts you get by dropping the compression in a race motor you can end up with a better motor with better parts and still save money.
