My 422 smallblock build

After rereading the thread I see you are using a dual plain and indicate you a mild mannered motor. I can see why Jones spec'd it like he did .
Some of the build parameters clash ... 2.08 valves and a dual plain for one .
I am excited to see how this cam works out !
Could be a perfect sleeper combo !
I have both an aluminum and cast iron W2 dual plain . Always wanted to make a sleeper 77 Magnum or 81 Mirada ! Keep it looking stock under hood .

I saw the dual plane too. I will NEVER get it. 4 hours on a flow bench and no one would run run.


Doesn't matter. To run the RPM it will take that much duration (whatever the hell I said earlier) and there isn't a single reason I can think of to run any less lift or a split pattern cam with a blown out LSA.

I went through a TON of cam grinders when I stopped picking my own cams when the new cams made less power and went slower. I spent a TON of money going backwards.

When you run a stick and you add exhaust duration and blow out the LSA to get the RPM after peak HP it absolutely KILLS power right in the gear change. Every single time.

They drive like **** on the street. They buck and chug and it's just nasty and miserable.

A little carb tuning and you can get the most "wild" cam to idle clean as low as you dare go within reason. It's not a low power Honda, so anything even decent shouldn't idle below 800.
