Thread: 383 stroker block grind

Tweet

Hello all!
I'm just building my first 383 stroker chevy, and i have one question about how much do i have to grind from my block? I had just mount the crankshaft and rods to see how much i need to grind, but i'm surprised about the ammount of grind i had to do! arround 0.158" it seems i will hit the water jacket of the block if i attempt to do it! I'm using eagle forged crankshaft with eagle H beam rods.
Please, any help will be very welcome!
Thank you, and sorry for my bad english!

Every block is different due to (core shift).

I'm using a 1980 truck block.
do you think 0.158" is too much to grind?

No, this is only a little over an 1/8 of an inch.After you get enough clearance be sure to add an extra .050 for the rod to grow.

Hi Erik!
Thanks for your help!
I feel more comfortable now to do this grind job!
Here in Brazil, is very dificult to find 350 chevy blocks! this is the reason for asking before attempting to do it!
Did you know if somebody has to grind much more than i do? or if some one already hit the water?

Usually the oil pan rails is where you need to grind the most, and these are solid metal, so you could never hit the water jacket.
