Re: Shafiroff 540
The Musi 555 short block, which uses a Dart Big M block, does seem like a good deal for $3800!
I was going to go with a ZZ502 short block for about $4400, and change the cam and lifters. I would also need to change the pan.
The Musi short block would need cam, lifters, (Don't know about cam bearings), timing set & cover, balancer, pointer, pan, pump, and pickup, but I would pick up 53 more cubes. It is also internally balanced. Plus I would probably bump up to an AFR 325 instead of my AFR 305 that I was going to use for the ZZ502.
I'm going to have to think on this for a day or two!
Of course I'll still use Mike Lewis for my other parts. I've bugged him enough that I feel I owe him some of my business.
