well guys I'm having a tuff time finding a aftermarket block so I have a line on a good 230 400 block sonic checked .226 finished bore at the thinnest ...with aluminum caps what HP level do you think I would be safe(reliable) with N/A??
Well, my little 400/512 build has been great at 755hp with no signs of any issues since adopting new valve train....I would go a bunch more if you keep the rpm reasonable and hit the tune up right. Mine is not filled, only has a girdle. I have been contemplating a 383/496 build with an F2 at 18psi....So I might be able to let you know at what point it lets go......
