Got a 67 289, wanting to stroke it to a 327 with a 3.250" crank and matching rods and pistons. Will I need to have the bottom of the cylinders cut so the counterweights will clear or will it be ok as the block sits?

you have to mock it up to see that. put in the front and back bearings, lay the crank, then turn it over to see. and you might also want to stab a piston and rod in and turn it around with that cause you might have to notch out for the rod to clear.

Maybe, depends on the kit. Most kits don't require clearancing, but some rods (like Scat forged) use cap screw rod bolts that do. I went with this style and had to have the shop clearance the bottom of the cylinder bores a hair. You might as well have the machine shop do it, because the block needs to be cleaned afterwards.

Thing with that is this. I want to make sure it'll fit before I buy it, don't wanna drop $1200 on a stroker kit just to find out I need more machine work on my block
