If it is a two bolt you could just leave it as a two bolt cuz it should be plenty strong but cuz there is more material than a regular four bolt. If you do have it redrilled have them drill it for splayed caps.

Just a little crazy!!!!!!

I agree if you are under 500hp and 7000 rpm then you shouldnt have any problems with the 2 bolt. If you are above that you may want to look into 4 bolt caps. You can have it redrilled for stock 4 botl caps but if you go to the trouble you might as well put splayed caps on. they are better anyway.

Ya, the 2 bolt wouldn't be too bad. Just use ARP studs and/or a main girdle to hold everything together.

When you tear it down, look under the timing chain for "010" and/or "020" cast into the block right above the front main. Those numbers (if they're there) are the amount of tin and nickel in the block. If it has both 010 and 020, then it's the strongest, hardest block there was. Of the 6 I've looked recently, 2 had the 010 and none had the 020 there.

I allways sell 4 bolts in the local paper to someone building a motor for their truck or grocery getter. they allways want a 4 bolt.

you can usually sell them for enogh to get 2 more core engines, then look for 4 bolt again.

Got to it a little early and it's a four bolt so I guess it all a moot point. Thanks for the info guys, I will now know for future use.
