Default 331 block clearance?

Hey do you have to do any block clearancing*sp with a 331 stroker with the stock 95 block? Any info on this would be helpful, can you do it yourself or would it be best to take it to a shop.

it really depends on what kit you are going to use. the guys at Coast high performance or dss racing can help you with that question. i know that you have to clearance for 347 though.

I clearance my own block. Not that hard. Took like 15 min with a carbide die grinder. I bought a jig from eBay that bolts where the mains do and shows you where to grind.

The 347 kits usually uses a 3.4" stroker.

Most 331's use a 3.25"?

I know if I didn't clear the block it would've hit.

I'm under the impression that some do need grinding and some don't......

Just search like, "347 331 clearance tool", or something. I believe it's TRE performance that sells them. They are a little overpriced for what they are but worth it saving the cash instead of having a shop do it. I also used some articles on the net for refrence also.

To install the "kit" is just like installing a lower rotating seembly, nothing special there.

Cant you just mark with some marking compound or something where it hits when you spin the crank, during your mock assembly?
