I want to do a stock rebuild and I plan on running nitrous and boost in the future. This is a just for fun kind of project to see how far the block will go. So is there a bearing that would be good for both nitrous and boost? And what about the gap in the piston rings? I'm just in the planning stage right now

 

my cars motor has been rebuilt from the previous owner because... Running N20 on a stock block. Now imagine boost... With that being said for the HP/Dollar or budget mind id build up the motor to handle a mildly aggressive shot of nitrous. Make sure and get a good nitrous style cam and as far as Pistons id get some custom nitrous Pistons from JE. I did that once on a Gen 1 SBC. They handled a 250 shot for over 200 track passes. Car was a mid 7 sec 1/8th mile car and drove it there on the street.

 

It has been done before. Look up xrambbc on here. Old setup made nearly 800whp with a big correction factor because of high altitude. Was still around 650whp uncorrected on all stock hard parts (even down to the rod bolts) and untouched stock heads. 2-bolt main rebuilt with wide bearing clearances and ring gaps to tolerate 20+ psi from a single turbo. The secret was keeping the RPMs < 5800 and running it on race gas because high CR.

The same could be done on pump gas if you can drop compression. Cometic makes some super thick MLS gaskets that can get you over a point lower.

 

Ah ok, thanks for the reference. If I wanted to go higher than 5800rpms I would just switch to ARP bolts right? My limiter right now is set on 6200

 

You could, but power/rpm put more stress on the crank and make the main caps more likely to walk. Stock pistons are heavy and spinning higher with big power is unrealistic.
