New Cast Crankshafts
We
sell cast cranks from both Eagle and Ohio Crankshaft.
These crankshafts are new cast pieces made with
modern material and
casting processes to be a great alternative
to 30 year old factory cranks.
Many factory cranks we check have stress cracks,
so even though your
crank has not broken yet, you may have a problem
developing that could
destroy your engine.

4.25
OR 4.500 CRANK CLEARANCE
This
picture shows the only area that normally needs
to be clearanced to put either a 4.25" or 4.500"
stroke crank in a Pontiac 400 block- although
any new part should be installed and all clearances
checked prior to final assembly because of factory
production variances.

Mag Oct. 07 issues
"It's
been 30 years in the making, but Pontiac enthusiasts
now have both aftermarket cast and forged cranks
at their disposal. In the late '90s, Butler
Performance teamed up with Eagle to produce
the first aftermarket Pontiac crank, a cast-steel
4.250-inch unit for 3-inch main 326/350/389/400
blocks. Just this year, Butler Performance released
4340 forged cranks in 4.000-, 4.250-, and 4.500-inch
strokes for 3-inch main blocks. The company
also offers 4.000- and 4.250-inch 4340 cranks
for 421/428/455 blocks with 3.25-inch mains.
"Before we released these cranks, the only option
was offset grinding a stock crank, which netted
an extra 4 to 5 ci," David Butler says. "Forged
cranks are so reasonably priced these days,
there's no reason to even bother with a stock
piece." |
