The tech guy at Pertronix that I spoke to was good and knew the product . He actually admitted the I was not the first to call with this question and was frustrated that Pertronix had not addressed the issue.
In reality it seems that their instructions may be the issue .  Appears that they may just be covering their ass and putting the final gear decision in the cam manufacturers lap .

Well Brent based on your experience that is good enough for me .

Looks like the gear that came with my Pertronix D133700 distributor will not work on my Comp roller cam .
The distributor shaft is .500
What are you guys running for this combo ?

The oil feeds in my TFS heads that supply the rocker shafts measure about .171 . Is there any need to restrict them further  or can they be left as is ?

Since the TFS valve springs are like 440 over the nose of the lobe what style of pushrod and wall thickness should I order .
Smith Brothers order sheet lists taper , double taper and a couple of different wall thicknesses.

As I assemble this 445 stroker build I am approaching the point where I will need pushrods . This build is using a pretty common recipe and I was wondering if there was an "off the shelf" push rod that will work ?
The build uses a 390 block that had not seen any machining since it was originally built . The deck surfaces were squared  , the heads are Trickflow , the camshaft is one of Brents custom grind hydraulic rollers and the rockers are Harland Sharp units.
If custom pushrods are required who is a good source and when measuring I would think you measure from the bottom of the cup to the tip of the ball ?

Will do , thanks

I think my part in this issue is done for now .
I didn’t build the engine and after taking a hard look at the intake I believe it to be the problem .I think the best course of action is for the engine to go back to the builder and let him sort it out.
If he refuses to stand behind it then I will reassemble the engine with another intake and go from there.
I am suspect of the current intake because it appears to have been Recently  machined on the port faces on both sides which I believe would narrow the intake ?
This intake is 60 years old and God knows what has been done to it and why .
