dizzy questions for a 454

[dodgedude99]

i have a HEI dizzy for my 454 HO crate motor. the probaly is that it wont sit flush with the intake manifold, it would have to go down another 1/4" or so.

do GM dizzys come in different lengths?

Is the hei out of a tall deck truck block? MSD has dist with slip collars to adjust the height due to differant deck heights. Are you sure the oil pump drive is fully seated?

 

[dodgedude99]

no the dizzy is an aftermarket hei version, i only paid $140 for thru Summit.
im pretty sure the oil pump drive is set since i prelubed the motor with my drill.

But did you then line up the oil pump drive to mate properly with the drive pin in the bottom of the distrbutor shaft? That pin has to drop into the slot in the drive shaft before the distributor will seat down all the way.

i couldnt turn the rotor after i put it in, does that count?

Nope. That just means that you have gear interference with the cam. You have to look down the hole with a flashlight and see where the "slot" is. Then figure out how the pin is going to be oriented when the distributor is properly inserted. Now rotate the slot so that it will be in the right place when the distrbutor drops in.

It might take a couple of tries, since the gears force the distributor to rotate slightly as the distributor drops into place.

Harry after you posted that i had to go out in the garage and check.

im a dumbass.
a little twist with a screwdriver, and the dizzy slid all the way in.

Just think of it as a learning experience. Most of us got to figure out ourselves at some point...

it should pull pretty decent with the 454, 465, and 4.88 gears.
