I did the same thing .....................

on my 377 had a few problems wish I had bought an aftermarket block as well . but one question I would like to raise is how much additional machine work is there to be done to the block ?

SOMETIMES the mains need to have a hone thrown thru them.... but, really if you were in a money crunch, take a new one, check everything closely, detail it up, hone cylinders to size and RUN IT. The machine work is decent.

Now a lot of machinists might balk at that as they are in business to make money machining.... I'm am not in the business of doing that. I'm in the business of making horsepower and designing the engine so you'll get a little different story that is unbiased from me.
man I wish I new this 3 years ago I could have purchased a block for about $1895 @ the time I think I spent $1650 on mine I was thinkin I would have spent $400 - $600 on additional machine work ! this market needs a good reputable machine shop that dosent try to bend ya over all the time . Thanks for the info Chris
