Opinions on Blueprint Crate R/B 493/440

chasb said

Thanks everyone My issue is that I don't have the specs on the original motor so I don't know what the actual bore is. I'm afraid that if it gets sent to a machine shop there might be enough room left to rebuild/bore it out further Then I wasted $2,000 or more and have to go from scratch anyway. I'm really stuck with this decision and me not being a mechanic I'm at a loss to do anything myself.

I will agree that the unknown of what is lurking in the short block (bore, crank, etc.) is something that anyone will need to know including a potential buyer for it even if you go with a crate engine for the replacement. So the way I see it you are probably gonna have to find out one way or the other.... You really need to find out your bore size. If you are not the one doing the removal and reinstall of the motor whomever that is can most likely help you. Once your motor is on a stand it would take about an hour or labor to have a Dial Bore Gauge stuck in the holes and seeing what you have....
