300 Turbo Cam

I plan on using a gasket between the flange and manifold, so that should help the dissimilar metal issue. I'll be making some clips like you. I'm going to mill off the heat riser "block" off the bottom of the intake manifold and install a plate over the exhaust manifold's side of the heat riser. So there will be no physical connection between the two manifolds.

The HD exhaust manifold is new from Stevens, but they have an issue with the heater riser mating surface being slightly off which causes a misalignment with the exhaust ports if you bolt it to the intake.

the heat riser is a headache for me.
mine is an open hole, needing plugged.
not easy to get a leak free seal.

on the outlet pipe, I urge u to reconsider.
examine carefully the outlet port on the HD. Does urs have a machined recess about 1.5 inches deep?
it's a very good way to guarantee u get no leaks if u can take advantage of the recess by 8 setting the pipe to the very end of that recess, up against the ledge left after machining was finished.
further, it aligns the pipe on the outlet same plane.
I wish I were allowed to post pics, I could explain so much easier
 
You mean like this:

The machined recess in my manifold is only around 0.5".

This is the Crower version of the Isky turbo cam.
It adds a little more exhaust duration to raise the rpm limit but is still a split duration to work well with a log exhaust manifold mutuelles entreprise.
Install the cam 4 degrees advanced with the intake lobe center at 110* ATDC.
Keep the static compression ratio below 8.5

I too had the same concern, but fortunately you are there.
 
I contacted Isky about grinding a custom cam with the Crower cam specs PMuller9 provided. They said the cam below is the closest they can come to that spec. Any thoughts? Paul?

It is close enough to the Crower cam to work as planned.

For those looking on:
This cam is designed to work with the HD log exhaust manifold.

Thanks Paul.
 
Do I install this cam 4 degrees advanced?
 
Never mind. The cam card says 2 degrees but I believe that's cam degrees not crank degrees.
They should have said 4 degrees.
They show the intake .050” opening at 6 degrees ATDC which puts the intake lobe center at 110 which is 4 degrees advanced.
