Stocker Cam Lobe Profile ? - Page 4

Yes Alan, I called Tim Cole, as you recommended. He took it like a hot potato, and passed it off to Chris Padgitt !
Ah yes, they too, want me to go away !

Chris is the fellow who originally did this lobe for me in 2004. Like so many, he too, I believe, catagorized this lump as a "torque engine".
I dunno ? maybe I broke that "mold" ?

Anyhow, I'm REALLY excited about this lobe that he came up with !
Also, because I learned from here, that I'm not limited to a single spring anymore... he discovered a dual spring that will fit right in, standard length valves.

Valves.?
YOU BET !
I'll be bugging ya' !

With the bit of tire spin that I get... second gear already comes instaneously !
The transmission gear change ( probably actually a tranamission change ) will be a winter project. At the moment, get this dealt with.

Considering that the exhaust ports for a 409 do not have a large cross section area, I agree with Mark, 1-7/8" is as big as I'd go with the 1st diameter. Not sure I'd go as small as 1-3/4", but it might work.

I think the 4-2-1 or tri-y is probably the ticket for a stick car especially. But you need the right cam to take full advantage of them, and you have to make sure you can get the correct firing order cam for the headers you build. You might be surprised how small and exhaust lobe you can run with a 4-2-1 header, and what it will allow you to do with the intake lobe and the LSA. Considering the lift limit on the intake lobe for the 62 409, that might be a really big deal.

Aubrey,
I had a similar issue with the Hemi at first. Lots of valve float at 6200rpm, I called the guy that the short block, heads and cam came from ( I bought them separately as funds came together ) and he told me I needed more spring pressure. Long story short I think I could have put springs for a roller cam in it and it still would not have done any good.
I finally called Tim Cole and gave him the card number for the cam, He actually laughed and asked who in the hell had sold me that cam then stopped when he saw the fellows name on the order sheet. He asked me if I wanted a cam that would work and I told that I would indeed like that.

It goes thru the traps at 8000rpm now. Thanks Tim!
