Stock Block series

Our local track has started a series called "Stock Block" heads up racing.

Rules;
Stock crank
stock block
200CC intake runner max on the cylinder head.
Any cam, rods, heads.

They have a class for small blocks & one for big blocks.

Well, we decide to take the Demon out in bracket trim.
We qualify 2nd out of 10 cars @ a 11.40.
3-10 was in at 11.49-12.02.
#1 was a 351W Fox body Mustang @ 10.95!

Well, we made it to the final & got beat by this Mustang.
Am I that blinded by MoPars that I can't see a 351W running that fast?
This same guy ran the power adder class (NOS) & went 10.02.
I still think this guy was illegal, but there was no provision for inspection, other than the racers word.

So, I'm putting together something just to clean this guys clock!

Which track is this?


Thanks Ray
