msd dist on bbc

[ozone eater]

i am new to the bbc so i dont know if this is typical. bought a 84697 crank trigger dist. was installing the dist like any other and the base of the dist is 3/8" off the intake. its a 9.8 deck with the efi edelbrock intake. i also run the moroso billet pump. to me it looks like the manifold was machined too thin were the dist holddown is. what am i missing?:rolleyes:

its either a tall deck distributor or it needs to still drop down onto the oil pump shaft...

i thought about the deck ht. is that the difference in a 9.8 to a 10.2? that is roughly 3/8 right there.

I would measure before doing anything. As said, you're either not in or the wrong dist.
I have a few before switching to dry sump, that just didn't want to fit in the damn slot!!
Almost as bad as a finicky converter sometimes??

Good luck.

Make sure the oil shaft didn't pop up on top of the pump. A few twists with a screwdriver will tell you for sure. Is this a new combo? What block? If you have the pump drive for a Merlin block in a non-Merlin it won't let the dist all the way down.

shaft wasnt down all the way on the pump. thanks for all the help! little scotch brite and the shaft fell right down onto the pump.
