I am goning to be building a forged 383 and was wondering if i really need to splay the main caps? I know that it will help make the bottom end stronger but is it that necessary? I am going to be running an eagle crank, h beams, srp pistons, gm 847, ported heads and intake. And there is a possibility of a little nitrous. Would i be "safe" on a 2 bolt block because it is going to be like an extra 500 to splay the main caps.

Thanks Scott

 

Any job, big or small, do it right, or not at all.

Since its going to be forged, I would spluge and do it. Power is addictive.

 

I would definatley do 4 bolt. I'll try to post some pics of the disaster I had with a similar setup on a 355. How does 4 rods bearings, 2 main bearings and, 3 damaged caps sound?

 

sounds like hell, thats what i am afraid of, i am going to end up wayyyyy over what i planned to spend but such as life i guess. This started out as a head and cam swap gone bad when i found out i had stock internals.

yeah, I was very fortunate and I actually had a stock 4 bolt block but Id def. do it. the rest will be forged so your gonna want to put some nitrous to it later, no point to leave a weak point in there at this point ya know?

 

I would go splayed also. Like was stated before, do it right the first time. I just so happen to have a fully-forged 383 shortblock for sale. If you are interested, I have 4600.00 into it with machine work, assembly and parts that I am trying to sell for 3800.00 It is setup to handle a 400 shot of nitrous, so in other words she is pretty stout.

let me know if interested.
