That is some great info Jim, thanks. I felt a little like a 1st grader sitting in a Calculus class, but good info nonetheless.
I spoke with a technician from Summit Racing and gave him all my specs and told him what I was trying to accomplish. He recommended these...
Yes, understanding cam specs can be a brain puzzle. I tried to simplify and even I am by no means an expert.
Kits are great in that it matches everything together. The cam however, has that 110 LSA that may aggravate your already high compression (you don't want engine "ping/spark knock"), but, the "short" duration figures may balance this out. Again, no expert by a long shot as cams come in so many flavors and sometimes it can be hit or miss. I used a Comp Cam with 110 LSA. My engine machinist told me I was going to be unhappy with it as he felt it too big. Very untrue, it proved to be a great selection for my combination. Loads of torque, fast, and with a 3 speed manual, 3.55 gears and tall tires I could coax about 16 MPG steady highway driving at 60 MPH. I was happy with my choice -which my engine machinist would have not chosen, but he was really a Chevy engine builder to start with.
Why not call Competition Cams directly? See what they recommend and then see if Summit has a corresponding kit. I like Summit and use them myself, and no doubt they have good people. However, I might just want to get it right from the horse's mouth at Competition Cams. Jim Butler Performance is another good Pontiac site that may be also able to help. There are a number of great Pontiac engine builders who can also help and you can post to get further references/opinions.
Also, throw a post on the technical forum, if you have not already, and see what feedback you might get from a member having a car combo much like yours. Lot of good members here with years of experience. You may get too much info and be even more confused! HaHaHa.
Just don't rush into a selection. Take your time to select a cam your comfortable with. Remember, a Pontiac won't sound like a nice rumpity-rump Chevy with a hot cam. Pontiacs have a sound all their own. Listen to some of the U-Tube videos on Pontiac cars to get some "sound" advice. Some have that great rough sounding idle, but these are usually the big/high dollar engines that are built for big power, speed, and need big cams to get it.
Hope this helps.
