Pick basics of new eliminator

[Dick Butler]

If a new Stock could be created, could there be a concensus on the basic qualities it needs?
Would it be Cheap?to buy?
Would it be many or few combinations?( Like a ford class or a chevy class or combined)
Would it be only Newer cars?(to add younger interest or identification)current cars not qualified to run due to rules limitation.
Would it be very limited modifications of motor to cut costs?( sealed versus spec versus claimer)
Would a class where all peoples current cars could run with a very limited motor rule allowing them to save money on trans and motor builds be okay? New pure motor , previous cars chassis to save money?

Easy

• Current Stock cars as they relate to body, suspension and tires

Two engine options Big-Block and Small-Block (all makes)
• Big-block and small block class with CID limit (say 480 BB and 370 SB). Assign two weight breaks for big- and small-blocks.
• List of approved heads weight break for true inline valves
• Make common intake/exhaust valve rule
• BB .600-inch lift, SB .500-inch lift, solid roller for both
• flat-top pistons
• Big-Block: limit induction to 750 cfm carb or similar size throttle body BB, Small-Block: 650 cfm or similar TBD Throttle body
Keep the induction small since that is what limits hp

Pro-tree Heads up only, runaway combos get a weight penalty.

Evan, it sounds a lot like the Old/New "Top Stock" with a few changes...it would be good for a few with $$$ but not for the majority of current racers. Plus, it did not do well when the original Top Stock morphed to similar rules. It was fun to watch but most races did not have full fields.

Sounds good. Alot cheaper than the current setups and no shoe polish.

Other ideas:

1) Maximum 150 lbs. valve spring pressure on the seat. Maximum 1.500 valve spring diameter. Dual springs w/damper maximum.
2) No external modifications to intake manifolds.
3) Limited to untouched factory intake manifold or aftermarket dual plane.
4) Roller rocker arms allowed, no stud girdles. Original rocker arm mounting configuration.
5) Deep oil pans (none below the lowest frame crossmember), no kickouts.
6) No port plates on headers.
7) Original OEM crankshafts or approved aftermarket only; no custom aftermarket billet strokers.
8) Three speed automatics and four speed manuals only, regardless of OEM configuration.
9) Steel valves only.
10) Rear wheel wells may be modified internally for maximum legal tires.

Dwight, Give them all an aftermarket dual plane intake AND a spec. 400 to 500 CFM vacuum Holley and I'm in.

If we are going to start from scratch I think that maybe it should be 1995 and later, No big blocks, only small block crate type motors and existing current V8s.
Back to my previous post I think that all combos should be fuel injected with 1 spec. 300 to 350 CFM dry throttle body on an aftermarket dualplane (no tuned port) intake.
Also weight penalty for OHC and multi valve motors.
