I enjoy running modified and modified stock, you can run .300-.500 under most modified indexes with a good engine, .600 and more under and the cost factor grows exponentially. Modified cars are extremely consistent, IMO.

And never tear down.

While we ran 3 SS cars at one time we were pretty well assured we had a "date" with the tear down barn where ever we raced. Part of the game but at this point I think a nice SS/CS car would be a major advantage....

If they have any doubts about some mods on say SS/CS, like making sure there are no external mods in the port area, or any valves have been moved, then they will tear you basically apart. At least the top end.

Wish SS/CS allowed the BRODIX heads. Then it could be the cheap Mod car class and it would be a start....

This. But that's too simple.

SS/CS is really a great class, we enjoyed running it for nearly 10 years. The challenge (like any hard run SS and GT motor) is keeping the iron heads alive. There are now 2 Dart head castings that are approved for SS/CS, which I believe have quite a bit more material in the combustion chamber and clamping surfaces in comparison to the Bowtie Vortec stuff we ran. It was really a great ET and speed to run, and no tear downs is always nice. Although Indy appears to be one of the only races these days that actually tear anyone apart anymore.

Mike, What if NHRA made untouched Brodix Spec heads only head to run in CS?

This would be closest to lower cost entry class for SS.

I don't think that SS/CS would be considered either entry level or low cost.

To be in the game, the heads would need to be ported (CNC) and probably welded. You'd need a good short deck block, a custom stroke crank (probably billet), good rods (Carrillo for steel or GRP for aluminum), Jesel valve train, titanium valves, top-shelf springs, retainers, locks, lifters and pushrods, etc, etc.

Any small engine like that wants to see a lot of RPM. The parts need to be light but strong and reliable. You also need a good trans and converter program.

I looked into doing an SS/CS engine, but chose SS/BS instead based largely on availability of good used heads and valve train parts. Head porters typically prefer grinding aluminum over cast iron, and they definitely prefer to weld on aluminum.

With the comp guys selling good parts for a fraction of their original cost, it just makes more sense financially to go with a modified class that allows them (even the V6 stuff). Even with the used stuff, you're still looking at 25K to 35K to get a good engine together.

I think SS/CS is real challenge to go fast. Challenge almost always equals a lot of time and money.

Just my .02
