SB 396 block question?????
I posted earlier about a 396sb.
The rotating assy is for a later style block 1-piece seal.
First will my current flywheel and balancer work with this crank.
I don't know if it's an internal or external balance with the new assy.
I have a 383 external set up now.
Second,since this is a later style block I get to use stock type roller lifters,and eliminate the problems with retro fit lifters {correct}???
What about the oil pan later style block have the dip stick on the pass side [correct]??? Which means I have to add a new pan into the price.
AHH the cost keep going up!

Some balancers come with a removable weight so can use them with either an int or ext balanced assembly, believe the flywheels are not interchangable for neither seals nor balancing types.

One piece seal cranks with an internal balance are an unusual breed. They use a neutral balance damper with an external imbalance on the flywheel. The reason for the external balance flywheel is due to the absence of the crank hatchet on the crank flange used on two-piece cranks. It's important when sorting through smallblock Chevy combinations to identify what it is that you are working with.
