RE: 390 truck vs 410 pistons |

I have already done both a drill bit test and an allen key test. Based on the results, the block could be a very good candidate for a 428, but that would be as far as it would go, leaving no room for future overbore. The block does have the extra main webs and is in very good condition as it was running very strong in my truck. If I have to bore the block, than I will consider going 428, but if I dont have to I'll just re-assemble with the longer stroke crank. That is why I am interested in the wear limits. I already have the intake carbs heads and other pieces to put the motor together. So this may be an easy decision. Paul G. |
