I woulld like to get some opinions on on my build.

74 RB-block .055 Callies Dragonslayer crankshaft, Callies H-beam rods, Diamond pistons (flat-top), Pro-Comp heads milled to achieve aprox 13.5-1 compression. Should end up 512 c.i. Camshaft will be roller specs to be determined by the builder/cam manufacturer. It will be a custom grind matched to my combo. Lifters will probably be Crower. Rockers will be determined by builder.

The motors going in a 73 Cuda 3800 lbs 727 Pro-Torque converter or ATI matched to the combo, 410 Dana Caltacs 10.5/29.5 slicks

I know the builder has painstakingly taken the time to build this motor with the best parts considering the budget I'm on (and I'm not second guessing his judgement).

My question is this, considering the output of this engine, what kind of durablility can I expect from this combo. I know the block is the weak link. The engine will never see nitrous, and will probably see 30-40 runs per season.

Thoughts/opinions Thanks Randy
