crower rod catalog

Post #1 by 69rustang » Tue Mar 19, 2019 3:22 pm

was looking thru it just for kicks....part # ML93902B3-8 shows 6.7" length 2.015 big end .927 pin but width is chevy-like .941 so if side clearance can be tolerated as some past posts indicate would this be a possibility?

Yes, you would have the pistons made for tight rod clearance and let the pistons keep the rod centered.
The 2.015 big end is for a 1.888" crank journal. I wouldn't turn the 300 crank rod journal that far.
Besides, you can have custom rods made for the 300 six for a lot less than $2100.

The BBC 2.100" small journal rods fit the 300 crank.

as a consideration....
some time back we discussed shaping up the spit hole rods.
there were numerous ideas.
has any progress been made on this idea?

or maybe more to the point.
is there any idea as to when the later rods become unreliable?

as in power numbers etc

the rods seem to be a sticking point
a long love affair with the 300 six.
my lastest and final fling is a fresh 300 in an 88 ford f350 dually 4X flatbed

They should be avoided for anything but stock rebuilds. The slant 6 has rods that are similar and have had failures well below the 300 HP mark. Use at your own risk.
