Those cams concentrate allthe power in a real low rpm range, best for towing where you get high torque, and good low end power, but no top end. And you don't need a super torque towing cam to do burnouts.

 

ahaha. def not gonna be towing in a 70 coupe.
i wanna build it more for torque. so couldnt this work? the whole kits about 90.00

 

You'd be better off with a cam that has an rpm range that goes up to 5,500 or 6,000rpm. Like 2,000-5,500 with a good street cam design, it'll make good torque everywhere. Wider lobe seperation angles work well, they produce slightly less peak power, but better torque across a wider rpm range, narrower lsa's tend to make more power, but concentrate it in a narrower rpm range. You don't need a big cam to make big power, but you also don't want to go too small, otherwise it'll have good bottom end torque, but fall flat on the top side.
