Thanks for the advice hotrod dave. I used to live in uptown Butte from 2003-2006. I had to move because of work. I kind of miss the Ice fishing around Holter Dam and canyon ferry (outside of helena). But anywho....
For my build I am planing on turning my 360 into a 408 with a forged crank, H beam rods, 4 bolt mains, , adding an oil cooler,and partialy filling the block!
Based on my research, moving away from flat tappets to a roller setup makes it that much easier to push the limits up into that 600 hp range.
Isnt 600 HP more exciting than 400?
And based on what ive read I think that this type of setup can survive in the 550-600 range! What u think?
