On a 454 should the crank pulley attach to the the balancer with 3 bolts or four?
I thought the 396/427/454 bolt configuration was 3 holes and the small blocks were 4 bolts.

Anyone have any solid input.....

Both SBC and the BBC use a thee bolt crank pulley. BBC has a larger cente hole and the centerline of the belt is different between the two. If you bolt a SBC pulley to aBBC engine it will throw belts because the center of the V is off by half the belt width.

Hi... It appears that Summit has a few products listed wrong....further to my inquiring why there seemed to be different bolt configurations.
Just another lesson in "don't believe everything you read"

Thx for the input
