Also i saw the block in the pics. Does it have cast iron mains or cast steel mains like the dart little "M" blks. Just curious, because i bought a little "M" block that had cast iron caps.

This lifter bores we probed out are fine as the Darts and Bowtie blocks the lifter bores are fine right out of the box, Most shops go to .875 or .904 depending on there build, We hardly ever bush back do to the expence.
We bore gauge all the lifter bores to make sure they are not to to tight.
Those caps are nodular iron caps and are one and half times stronger thenthe a standard GM grey cast cap. It is the same cap as far as material as the Little-M Sportsman block
Thanks Carl, do you think those caps will handle. about 850HP, my plan is to run about 20%nitro (with alcohol)on stacks injection with a 434" Dart little "M" blk, good internals. I know the best deal is to change too billet caps but i'm already built.
Zip.
If I read this right the Dart Little-M Sportsman block is designed for 900 horse.
