I cannot find a 4 bolt block in michigan, But i found a 2 bolt for $200. I want to build a 383 motor and possibly use NOS,Can a 2 bolt handle this, or does anyone know were i could get a 4 bolt block bare.

 

according to everyone I talked to the 2 bolt can handle alot more than its given credit for. With studs insted of bolts it can handle about 500RWHP I told my machineist i was going to be running a 150 shot on my 383 and he said the 2 bolt mains would be fine.

 

I asked Nick at Nu-Tek this and he said he's only seen 2-bolt caps fail once, and that was on a circle track motor that was accidentally running 60* of advnce and the cap cracked. Apparently the'yre not a common point of failure.

 

i FOUND A 4 BOLT BARE BLOCK FOR $500.00 OR I GET GET A 2 BOLT FOR $200 IS PAYING $300 MORE FOR THE 4 BOLT WORTH IT?

 

If it's worth it to you, no one can tell you otherwise.

 

Can't you swap the two bolt to a four bolt for under $300, by buying new caps or something?

 

You can have the 2-bolt main splayed to a 4-bolt main. I have no idea on the cost.

 

A lot, a buddy of mine just had it done. But it looks awesome!
