Thread: Cam Selection, have specs.

...hey Rob, yes by 1/2" I meant .050 {when I type I know where the all the keys are to type 1/2" w/o looking. To find the '5' & the '0' keys I have to look, so it's easier.....}. Ok, so you have a Desk Top Dyno also. I just got mine a couple of weeks ago. There fun to play with, huh??? Anyway, it looks like Comp Cams recommended the #3 cam that I mentioned. When I called I talked to Matt he was great on the phone. In fact, since Summit, Jeg's and SD Chev were all out of the cam I wanted, I just ordered it right from Comp. {I called Comp 3 times & one of those times the guy I talked to was sort of 'in a hurry', may be it was break time??? But once I talked to Matt I just asked for him everytime. So you might ask for him if/when you call back}. Oh I got a 4/7 cam which reverses the number 4 & 7 in firing order sequence. They say it gives you a flatter Tq curve & the engine runs smoother & cooler. They can grind this on any cam. I saw where Comp also has a 'Cam pick' program that's available for $35 bucks. I thought about getting it but then I had to do something quick as the guy is already working on my motor.
LOL @ '70 Nova is out of warrentee! .;.... In fact I bought a '69 Nova that had the FULL factory warreentee once. Now that's good & bad. The good part was the warreenttee {although it & the car are l-o-n-g gone}. The bad part is that you've got to be in your 50's to have done this ...
All I know about break in is Comp told me to have my engine builder pull the 2nd spring for break in. In fact do I EVEN have 2 springs per valve??? I'd better go ask some 'valve spring' questions..... But I belive pulling the spring is only for the Extreem Energy cams.
Yes I also wonder about what the Desk Top has said my motor will put out. I HOPE it's right! They say it's to within 5% +/-.... Plus would be nice, huh???
And just remember to think TORQUE! more than hp..... Look at the Tq. @ 2000, 2500, 3000, 4000, 4500, 5000 RPM's. The largest cam that I ran for you put out 384 Hp @ 5500 but only 340 Ft. Lb's of TQ. @ 2000. The smallest cam only put out 346 Hp @ 5000 but it did 389 Ft. Lb's at 2000. Torque is what will make your car fast on the street ESPECIALLY with a stock converter......
have a good week end Bill

Well, like they say,
Horsepower is how fast you hit the wall,
Torque is how far you take it with you.

Anyways, I think I'll go with the #2 cam, nice torque curve to match the horsepower.

I'll let you all know how it goes just as soon as I start her up.

Any other ideas for the valvespring removal would be cool also

Thanks again,

.....good quote, how far you take the wall with you.... Yeah, #2 is a good choice. I know I went one under what Comp recommended to me. I DON'T want to have to buy another Tq converter! Yeah, I'll ask my engine guy r/e about the valvespring removal. I'm sure he's not going to be to happy. He recommened AGAINST me using the Comp Xtreem Energy cam & I thing THIS is why! He probably already knew r/e the spring thing....... Hey your in Lompoc, were're neighbors. I'm in Ojai, Ventura County....

Yummy! Lompoc=Anderson's. Best pea soup on the planet. Anderson boys used to run a flathead rail. Wasn't as good as the food, though.

Heh, Yup. Got us zeroed in
'bout 20 miles east to Buellton, if you wanna get all technical.

I might not go with a Comp Cams perse, but any cam with similar specs.

Any good muscle car meets in the area? You'd think so, being Sunny California and all

Thanks,
