The best part? Summit is less than 15 miles from the house. Convenient to say the least.

Dave,
I've got two complete 2V Clevelands one of which is in my '71 Mach 1. I plan on building that one but the other one is certainly up for grabs. I don't have any detailed information on casting numbers or condition right now but wouldn't mind looking for you. I picked that one up at the same time as the Mach 1 and just stuck it in the building with the rest of the "I'll get to it later" pile. Let me know what you're looking for and I'll check to see if it matches your needs.

Again, thanks.

Jeff

No rush Jeff, just some casting numbers from the block and heads someday when you have time.... The 2V heads work good for a street Clevor engine......

Nobody has weighed in yet on the rods, so I did a little research. These look like good rods to begin with. I think I'd magnaflux 'em, have a set of ARP bolts installed, re-size the big end and call it good.

Measure the diameter of the bolts in the rods now and then measure the diameter and length of the new ones before you lay out the cash for them. Better to find out now if they are the wrong diameter and length.
