Large Journal
Use P-Series main bearings where higher eccentricity is desired to narrow bearing contact patterns and to provide increased oiling to rod bearings

Can you get 400hp out of a 350? ›

On the power side, we selected 400 hp as a reasonable output. Building a 350 to produce 400hp is really no big deal, but doing it for chump change is decidedly more difficult. In this case, chump change meant building our small-block with a ceiling of just $1,000.

What's the difference between a big block 350 and a small-block 350? ›

While small block engines still have metal and cylinders, they are typically smaller and fewer in number.

In most cases starting out with 12 degrees of initial advance is about right. However, that may result too much total advance, which should be limited to around 36-37 degrees so the distributor's advance curve may have to be altered. How that is done will depend on the distributor you use.
