389 Technical Pontiac Guys Need help with my 1964 Bonneville

[Rocky]

I stand corrected

Who makes a true 068 pontiac cam? I want to make sure I avoid something I have heard of, something to do with cam cut onto a generic profile or chevy profile....you get the idea i just can't spit it out right now without digging for the right term

[Waddayacare]

O.E.M. 068 specs are............

Duration @ .050 Degrees Intake/Exaust - 212/225

Ave. Duration Degrees Intake/Exaust - 288/302

Lobe Center Degrees Intake/Exaust- 113/118

Lobe Separation Angle - 116

Overlap - 63

Cam Lift Intake/Exaust - .272/.271

Gross Lift Intake/Exaust w/1.5 rocker - .408/.407

Gross Lift Intake/Exaust w/1.65 rocker - .449/.448

Match these numbers up to a common cam maker because an N.O.S. one will cost you a small fortune. I know, I recently sold one.

Thanks guys for all the help so far. I will stick with the stock intake and install as recommended tri power cam. Any recommendation when it comes to top of the line head gaskets? I know edelbrock makes some but I do have a full GM NOS set.

I've always had good luck with Felpro gasket sets on my Pontiacs.

Jon.

A little late chiming in here but...
The '62 389 I have slated for the truck in my avatar was a factory 10.25 compression TWO BARREL. It cranked out 368hp (gross rating) and ran great on the crap we pump now. The Star Chief it was in was WAY more than capable, even with the Olds Jetaway HydraMatic and 2.91ish gears. Admittedly, when I got the car, it had been fitted with 1971 400 small-valve, small-chamber heads and matching intake.
Subscribed, I'd like to see how this turns out, my goals are similar. The truck is already equipped with a Grand Wagoneer Dana 44 with 3.31 gears, that should help a lot.

I see that Edelbrock has a high perf. Steel shim sandwich head set, much like my NOS GM head set of gaskets....obviously I would like to avoid using any thick or inferior head gaskets that would drop compression or only seal for 5 years.....any input on this subject?, or am I gonig with NOS and copper spray.....lol
