Thanks
Is there enough material in the block when using the aftermarket mains it's not too weak? I'm thinking about a .030 with a 4" stroke for a 408(I believe) currently running a 383 with 6" rod, 13.5 comp, lunati 618 roller and 215 RHS heads and really like the combination. Runs 6.50's in the 1/8 in 2600lb car, I feel like a few more cubes would help and i have a spare 350 block in the garage just waiting for a build, and that would be worth about 20ci and be an interesting combo to put together. I dont really hear too much about them and was worried there might be a reason. Thanks for the input,
