deviating a little bit more... is there a current good reproduction of the "pink" rods? or a good source for reasonably priced originals?

Thanks John.  I would like to know what spring Jerry uses with the comp cams 30 30 12-107-3 grind.

I plan to use the springs you suggested with the one 30 30 cam I still have.  I also have two of the 12-107-3 cams and am wondering if I can use the same springs.

As for Pink rods, there are still some originals out there.

The springs that Comp Cams recommends for the 12-107-3 are rated at 105lbs @ 1.700" and 273lbs @ 1.250", part # 981-16.  Don't know what Jerry M. is using.

Summit Racing quotes the ratings for the Sealed Power #VS677 at 76lbs and 194lbs.  Don't know if there are other springs with the same number that are rated different.

Using the Comp Cam springs.  About 115 on the seat, these are very forgiving and will last a life time.  I think $75.00.

Any late '60's 3/8 bolt connecting rod will work fine for the 302 application.  Just have them shot peened and magged with good ARP rod bolts and you're good to go.

Yes, last year at the Cecil County points race, August 2011.  It's about 8600 rpm each gear and 8300 through the traps.
