Re: 2015 Rules
 

GT was specifically created for new cars with old motors including the jelly bean fwd conversions. After a few years and many requests, NHRA allowed the old cars with not matching motors in. I was asked to write a letter just because they needed a letter from someone, anyone. But what better car than a SS/AH that has just been priced out of the market to find new life in GT. They are pretty good, but no better than other combos. Time will tell, but it's still just 5% of the cars.

Re: 2015 Rules
 

When Indy opens up with a limit of 150 entries in S/S and I enter, I figure that I might have a chance of getting in as an alternate. Then NHRA jumps it up to 160 - 170 -180 there is no way of me racing. Sure, you can withdraw at that point, but NHRA still keeps your entry fee and will credit it forward, but "No Refunds" at that point. If they will allow 180 entries, then they should list it from the beginning and you can take your chances. For the amount you invest to travel and enter, it should be an "All Run" field. Plus, when the fastest hemi car on the grounds qualifies 100th in the field, (100 721 SS/AH Rick Houser, Pasadena CA, '68 Barracuda 8.493 9.30 -0.807) time for an adjustment on the index. Dyno

Very accurate statement Ed.

360" DP, 11.4 CR, 2.02/1.6 valves, 4x1.75" throttle body... rated 275 HP...

Throw in there the 352 CJ..... 11.25 CR, 2.08/1.6 valves, 4x1.75" TB.... rated 285HP

Re: 2015 Rules
 

Jeff, the easiest thing would have been to take a look at the specs, and give them a more realistic hp rating going in. Ray Chareles, in his present condition, could compare the specs to known engines, and say "Are you kidding?"

SS/CS Heads,
I talked with Bruce this afternoon, he told me that presently only two heads are approved ( both from Dart for the chevy), one is a 180 cc, the scary one is the 230cc 308 cfm head as cast. I got the feeling that just any iron heads wont be the deal. But they needed to have something to help the Chevrolet guys as they were cracking heads in short order. Knowing what these engines can break, I would not wish that on anybody. While I am concerned we all know that port volume or cfm do not only make the HP, I have worked an awful lot of stuff to find .07 over the year, so I cant imagine we will be obsolete, YET. Bruce and the NHRA seem to be aware of how touchy this is. The good thing is that there should be more trying out the SS/CS water, I can attest to the warmth (DAMN near boiling!). My biggest fear is that the class dwindles to 5 or 6 cars then gets written off.

Re: 2015 Rules
 

OK, I guess mine just ain't as good as everyone else's. I think I will change to something better next year. I want one of them LT1 motors like Ricky Decker or Ed Wright got. According to the world famous Nitro Joe, that thing is pretty good.

Re: 2015 Rules
 

The 360" heads are bigger, and on the same flow bench the intake ports flow over 40 cfm more with more compression plus over 300 cfm more throttle body and 10 more cubic inches, rated 4 Hp less. If I could not take all that and blow an LT1 away heads up I would go shoot myself.

Ashton,

Guess I got your blood pumping with that text this morning! Maybe I need to build a CS engine. ��

Re: 2015 Rules
 

The new rule change is for any aftermarket inline cast iron cylinder, not OEM based. I learned about the proposed rule change from a cylinder head porter that was doing a set of LS type GM heads, although they were only available in trucks and not cars. I spoke directly to NHRA last year and they confirmed they had approved the LS cast iron head and were considering allowing any aftermarket cast iron head, which just happened.

This does not have anything to do with Vince Perno; this was proposed last year.

If you have never seen the ProAction Chevy based cylinder head, you will have a rude awakening. With the ProAction 14 degree head, there is not a Ford or Mopar that will be able to win a heads up. The head is available up to a 300cc runner volume and they will flow 400+ CFM's.

The heads hold records in the Nostalgia classes.

Just take a look at the head:

Re: 2015 Rules
 

Vince, I was told a complete different story and that ANY aftermarket cast iron head will be allowed. Was also told that the GM LS cast iron 1999-2000, 6.0L,OEM truck 873 casting cylinder head was approved. This cast iron head, untouched, already has 210cc intake runner volume with a 2.0" intake valve. Add bigger valves and some extensive porting, they will flow 360+ CFM's.

If any of the Ford racers are interested, I know were a pair of brand new untouched RHS Ford, 20 degree cast iron cylinder heads with 225cc intake volume heads and 57cc chambers, are located.
