Then check out some of these Comp cams, depending on where you want your power band.

That one, which is the XR265HR, or maybe the slightly higher XR269HR 216/220 (100 RPM difference on the low end and marginally more lift).

I am going to use Scorpion Racing Springs. SRP1218 Looks like the specs are the same as the PAC's.

1.290 0.885 1.055 0.650 130 @ 1.800 318 @ 1.200 313 1.140 0.600

Best of all, made in the USA.

If they use a 1218 part number, you can about bet that they repackage the PAC's. How much are they trying to sell them for? We have a package with the cam, 1218 springs, and hardened pushrods for $589.99 plus shipping.

They get $13.00 for pushrods, and $11.26 for valve springs. According to Scorpion, they make all of their own products.

I assume those are "each" prices, and if that's the case you're getting it pretty raw. Even Comp Cams doesn't make their own valve springs....they have some commissioned and made to their specs, but even as big as they are, they don't make them themselves.
