Sbc block ?

[hipower17]

i always wondered is having a block with 350 mains an advantage to having one with 400 mains?

[perfconn]

Yes.Less bearing speed.

[hipower17]

does this go for rod bearings as well?

[keeks]

Yes it does. That's why many have gone to the Honda 1.88 rod journal.

[perfconn]

Crank is lighter also.
