1. 69 crank failure is documented.

2. Boss block is the weakest of the three and a little better than 1/2 the strength of the R-Block.

3. 70 Bud Moore Trans Am cars ran 10.5:1 and made between 460 - 490 HP. You'll need some Trans-Am rods, Bud Moore Mini-Plenum intake (which I have if interested), 850 holley, fairly nasty flat tappet cam .600/ 324, some head work like raised intake runners (which you won't read about) and light weight valve trane and a few other odds & ends.
