main beading clearance sbc

[m.lion]

Mains are 2450. I have 002clearance. Is that enough? Motor is a alcohol fueled motor.

[perfconn]

No.You need at least. 0025 but. 003 is better

[go2fast]

This is if you have a straight crank and a good line hone on the block
Alum Block we run 1.8 to 2 and about 3.8 at the parting line
Steel Block 2.5 and about 4 at the parting line

[perfconn]

Like to know how you can bore and hone a hole and end up with two different dimensions opposite of each other

[go2fast]

The bore in block will be round 2.641 for a 350 main or 2.861 o a 400 main the bearing have about .001.5 taper in them per side Terry you know better then that
