Are you still going to run the serpentine blower pulleys or are you going to some 8mm's?

To be honest I am not a huge fan of them but I am sure they will be on there for at least a little while...

I think Greg left 'em on just to piss Ginger off.

I haven't really thought about it. I will probably keep the serpentine blower pulleys if I go with full interior.

Anyone have a clue who's cam Greg was running? Jeremie said he thought it was a Chris Straub grind but I e-mailed Chris and he said that it wasn't his.

It's 00K2A 139456. I was thinking it might be a Crane Cam.

Look at the end of the cam, if it's crane it should say crane. The 13 indicates that it's for BBC, 945 will be the type of cam/grind it is. The copper paint or die between the lobes also looks like a crane. Call crane they'll tell you exactly what it is. With a number like that it's not a custom grind it's a catalog piece.

We looked at it pretty good. I don't think it's the original cam just a new grid of the original cam.

edit: You can identify a genuine Crane cam core by the distinctive copper plating between the lobes.

Is it a solid or hydraulic roller?
I run a hydraulic roller crane PN 139651. The number on yours is close.

So here's some food for thought.

I have decided to run a direct drive set-up but I am not sure which way I want to go. I can run what I have which is the TCI Front Pump Drive which is a (2) piece or I can run a (1) piece A 1 type deal.

I really don't have any negatives thoughts about running a (1) piece A 1 type Front Pump Drive since I will be running a Billet Steel Flexplate. The only down side I can see is the cost to buy one.



What I don't like about the 2 piece TCI Front Pump Drive is that since the motor plate is 3/8" thick I would have to run an adjustable slip collar. There needs to be 1/8 to 3/16" travel from where the pump drive is bottomed out in the transmission to where the slip collar is bottomed out in the flange. I guess I just don't like the fact that the slip collar is spinning inside the trans case and I am just wondering how likely it would be for the collar to loosen up and create some damage?

I measured the flange internally and the spline gear in the flange doesn't start until about 5/16 into the flange (I believe the spiral lock rides in this area). But since I am using the 2 piece lock collar that rides on the outside of the flange then I think I would just subtract 5/16" from the motor plate size 3/8" which equals 1/16". So if I start at (b) which is the spiral lock slot for no motor plate and measure 1/16" towards the engine that would be the starting place for the lock collar. Then set 1/8" to 3/16" for travel.

It's a solid roller.
