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 .

As far as the dual plane intake and 2.08 intake, it’s been done with pretty good results.

And that was on a stock stroke 360.
The heads needed a valve job when I bought them and they were already sunk. The 2.08 was readily available in the length I needed so it was an easy decision.
The reason for the dual plane is this car will primarily be a street brawler with an emphasis on low to mid range torque. That intake should still be able to make good power up to about 6800 and I don’t plan to ever spin it that fast, at least not intentionally :)
