I paid a premium for NOS X blocks and R1s. I paid 3k a block providing they sonic test good prior to payment.

The part that sucks is with both the X and the R1 your going to put about $1500 in a block to have it ready to assemble.

So its $4500 bare in the stand properly preped by a ex mopar racer who knows the ins and outs.

The X is a very unique block, they do not move or shift. No need to bury then in the backyard.

There are more then these on ebay currently.

I see R blocks on ebay often. Are not alot of the higher hp crate motors R blocks or 340 resto blocks?

But I do understand the shortage as if I were looking I would probably never find one.

Good 340 and 360 blocks can as we all know take alot of abuse. Ive cracked one and it I feel was only due to the half fill of hard block holding heat as on shutoff it would snap and pop in the same way you hear your exhaust system cooling off.

Jegs has 10 of these. $3300
