The tranny is a C-6
The only time I ran premium fuel was to mix with a 1/2 tank of regular because of detination.

I am sure that what ever cam I use to go with the higher compression be it a 801, 941, or what else I find that may work, I probably wouldn't notice much of a difference in torque with a load on it.

I always have a problem with hotrodding what ever I build and my intentions with this motor were to make a good reliable runner that the woman could drive when she wanted to and to get decent milage.
Well I guess the forged pistons changed that thought.

I know there is nothing like the sound of a good lopey cam!!
So I will start researching what cam I want to use.
I think that I could probably take care of the pinging with a cam that is made for the higher compression with dialing in the timing.

One more question.
I know that what ever cam I go with, I will need to change out the performer manifold.
I have a factory aluminum 4 barrel manifold on the shelf. The porting is much larger than the performer but they are both made in the same configuration
Would this manifold be worth using or would I be better off using a Performer RPM instead?

Thanks for all the help with this issue

I used an Edel Performer 390, which is basically a Performer, and it worked great with good low end and rev'd to 5000RPM and kept pulling to 6000... I know that's a lot for a Performer, but it did work out pretty decent.

The consensus around here is the stock 4bbl is just as good as a Performer - if you're look for more performance, get the RPM.

Good luck with it! And keep us up to date!

Huh????????????

 

Hey Krewat,

Do you know what kind of vacuum you are getting with the 292 duration cam?
No Vacuum issues?
Also,
I will probably try the factory aluminum manifold at first and see how I like it.
Not sure what RPM range it is made to perform the best in

 

Performer RPM- 1500 to 6500 RPM's

 

Oh, at around 16BTDC, I got only 11 inches of vacuum idling at 950-1000RPM. That's one of the reasons I setup the vacuum advance "backwards" on manifold vacuum, pulled initial way up to 20 at idle, but only 10 when starting. It was the only way to get the thing to idle well without loading up with fuel and totally killing my brake booster at low RPMS (even with a vacuum resevoir)...
