But its still a rule?

Talk about opening up a can of worms...

Guys, just in case you missed the memo..Sam Tech is the sponsor of the Factory Stock Showdown. All the modifications are within the rules. Remember, NHRA is the organization that allows FORDs to use CHEVROLET rods in their stock Elminator engines...

MJ, the Australian School Bus 390's came with the Chevy rods!

The OEM's dictate the rules on these cars.

The cylinder heads are CNC ported as shipped by GM and they are part number 17802818.
They feature:
• 12 Degree Valve Angle
• 2.205" titanium intake valves
• 1.615" sodium-filled exhaust valves
• Max-Life Beehive-type valve springs
• Valve retainers and locks
• Intake and exhaust stem seals
• Intake lash cap
• 275cc Intake Port
• 90cc Exhaust

There is also another version of the 427 COPO engine used for Factory Stock that runs the LSX-DR cylinder head engine with larger valves and a 313 cc intake port and 110cc exhaust port. This cylinder heads run a CFE designed intake manifold with a Holey Dominator sized throttle body.
