Is the 327 a small journal crank or large journal?
I actually prefer the earlier 327 small journal crank engines, they have forged crankshafts while later 327's had large journal cranks that are cast. The cylinder casting #'s are important too. You might have a diamond in the rough with the right casting numbers. I think you will find that the 327 will surprise you with the power output. They have a better stroke / to rod ratio than a 350. 327's have a 4.00 inch bore by 3.25 inch stroke. If it is a small journal engine make sure you replace the rod bolts. The factory small rod bolts were weak for higher power ratings. Sounds like it's going to be a nice rod!
