Explain to me again, please

SCCA gets around the parts availability problem by having a 30 year rule. No car older than 30 years in national competition in "Street" (which is the closest class to NHRA Stock). It does provide a progression to more modified classes as cars age out.

How many Stockers out there are older than 30 years compared to newer? Would you rather have a 30 year rule or pay $2K for lifters?

Got one 52 years old, one 36, and the ''New" one is 7.

Good luck trying to get that to fly! The funny thing is, I (me, Billy Nees) would be OK with this. It would sure get NHRA's Natl. Event fields where they (NHRA) want them to be.

Let's look at this another way, "would you rather have a 30 year rule" or a valve spring rule?

NHRA started the "new" Stock Eliminator in 1972 with a 20 year rule and it didn't fly.

Valve spring rule gets my vote.

Roller lifters have been OEM in many motors starting in the 1990s. There is probably 1/3+- of the current stockers using them now. Many if not all were originally hydraulic. It would be naive to believe cam grinders are not taking advantage of having a roller lifter for those motors. Other advantages of these combos are programmable ecu's and efi.
I don't believe rollers for everyone are another step towards SS. Having them available to all would take that advantage away from the "modern" combos.

200 lbs might work on a small valve motor.

You would think that if pushrod to lifter angle was a major concern, the 273/318/340/360 MoPar "LA" engines would be the most effected.

Terry, if I might ask here.. What combo is your car ? OEM hydraulics or solids?
