Default Looking for 4 bolt main 460 block

I'd like to build up a stroker 460 engine for the street and was wondering how I would identify a 4 bolt main block? I've heard some DOVE blocks have 4 bolts, so I'm going to start checking out all the cars for sale in this area to look for one plus I guess I could start looking on ebay... Would like to avoid shipping charges, though and get one locally. Thanks, Roy

Why do you need a 4 bolt main block? 429/460 blocks are strong engine blocks and unless you are going to be making some ungodly amount of HP you don't need 4 bolt mains. For most Street and race applications 2 bolt mains are more than sufficiant.

If you want to get a block locally it would help your search if you let people here know where you are.

Most common is to use a 2 bolt and use an ARP main stud kit.There are main girdles also but i 've never used one

You don't really need the 4 bolt mains untill you start getting in the 800 hp range. The 2 bolt blocks a really strong and pretty inexpensive.

Unless you can find 4 bolt one really cheap I wouldn't waste the time.

And if you MUST have a 4-bolt block you always have the option of installing a set of aftermarket 4-bolt main caps in a 2-bolt block..........

I really don't think I'll be tapping 800 horses, I just thought that it would be worth looking for one over the next year to build for future use. I live in Oregon and there are lots of good cars up here in the Northwest. I was just hoping to learn how to identify a 4 bolt main block so I could look for one. They can't be quite as hard to find as the Holy Grail Is there some distinguishing marks on the outside of the blocks that identify it as a 4 bolt block, or do you just have to start looking under oilpans??? Thanks, Roy

The only way to know for sure is to drop her drawers.

Default Some you could skip maybe...

I think you could skip any blocks that Are D1xx or later...I don't believe any of those (except for one weird one perhaps) have ever been found with 4-bolt mains.

I think they're all D0xx and earlier blocks that have the potential.

And, what's your time worth? If you're hell-bent on 4-bolt mains, buy main caps and do this:



That's a common D1VE narrow-rail with Blue Thunder caps on 2,3,4 and supposedly will hold 1000fwhp.

Yes they are almost as hard to find as the holy grail. You will not find one in a wrecking yard. If you do... nab me some CJ heads while you're at it. Better buy a couple lottery tickets also. :wink:
