I hear you, I do agree, that list is old.
Curious still ( not trying to be a smart a..) how many members do have door cars N/A running sub 8 sec time slips here ?
Tom
Tom,
Not to be a smart a, but to what purpose would someone set out to build a sub 8 sec N/A door car??? Top Sportsman allows N20, Q/16 does too, what there is of it. Don't need that much to run SC/SG (Although it would be nice!!) Most heads-up stuff isn't NA, and if it is, there are chassis/tire/weight restrictions which keeps the cars from the sub 8 second zone.
This is what I mean by a niche market..what you guys are calling "Hard Core" racers, even the opportunity to race those cars is dwindling.

Billy, I am, but I guess I am in the minority.
I am going to run an Index class with 7.60 ET and 7.50 break out.
I have B1 originals with titan. 2.30" and T&D 5/8" shaft rockers.
With Predator heads I could probably skip spray, or use very little.
Most fast cars here, have B1īs orig/ MC or 572-13 heads, and the step up to Predators with new headers, pistons and what you can sell your old stuff is pretty big, for me anyway.
I tried to answer the question, from my perspective.

Tom,
Your perspective is exactly what I was looking for, I had no idea such a class existed, and the motivation/cost to move from the more conventional stuff is exactly what I'm trying to understand. Diablo's perspective is likewise unique, as many of us wouldn't have a clue what competing in that arena is like. I understand where Tom(cat) and Al are coming from a bit more, as they race the southwest as I do, but what's going on in the east and southeast would probably suprise me.
So, With your short season, If you were to run this 7.60 index, and compete for a full year, how many passes 40? 60? how many do you put on your current combo before you take it apart?

This class is called ProStreet, but doesnīt have anything to do with your class with the same name.
Basically a fixed ET bracket racing but with a Pro tree start, which is all I want to race. Only door cars, with minimum weight breaks for Big/ small block and a penalty weight for clutch.
A new faster class called SuperProstreet started last summer with 6.90ET and no minimum weight, and would fit my Haas car even better, but way out of my league for engine budget.
I have not raced since 2002, and that was with my Coronet-69, so I donīt know exactly how many events this class has total in Sweden. Probably about 8-10 weekends.
I will start out slow, without spray in ET super pro, even if I donīt want to run handicap starts, but I need seat time and sort out bugs N/A before I will buy a nitrous converter and a fogger.
With good( constant) vacuum in engine and no big changes in valve lash, I plan to keep the engine togheter for the whole summer, thats a big if....

Well, since they let people start changing bore centers and deck heights, the name on the engine doesn't really mean squat anymore.
Absent this, the winner would probably be decided between the Ford 385 series engine, 4.90 BS, 10.320 deck height and the RB 4.84BS, 10.725 deck height depending on how much crank you can fit in there, even the tall deck Chebby is way behind at 4.84 BS and 9.8 deck height, so you just couldn't get the inches out of it.
If you're cube limited, the Ford is gonna walk away with it, just because you can get more bore and thus more valve and rpm for a given displacement. This is demonstrated by NHRA Pro Stock. S/F.....Ken M

Ok, I dont know about anyone else, but for 2500 dollars more than I have in my set of -1's . I could have afforded to buy a set of predators. We have the jesel 1.6 rockers, 1500+ worth of porting, 2.3 valves, 1.64 springs,ti retainers...ect... If I was doing it again, I would have went predator from the get go and have head to grow in.

This reminds me of
Years back when the local pulling club took the Nitros off me a guy told me (he had a 500ci at the time) if I didn't have the money to play with the big boys then I should stay home. Well that pissed my wife off and we "found" the money and bought our first 496ci and won the points that next season.
Now last year a guy with a schmit 650 told my wife that we could never win on a power track and only on driver tracks..... Well let's just say pissing off my wife gets me new motors 
Does she have a sister that thinks like that, Daddy wants a bigger motor!

you don't need 10,000 heads to race in a 10.90 index

There is nothing wrong with the price of these cylinder heads . I will say this 1000 times and it will be true every time .
IT DIDNT COST ANYMORE TO BUILD MY ENGINE BECOUSE ITS A MOPAR ... I JUST HAVE LESS OPTIONS TO CHOSE FROM .
Crank, pistons valves , intake manifold , camshaft, pushrods ,valve springs, valves ..cost the same
Does my 6.0 cert car care if I have a Mopar headed engine in it ??? or a barracuda body or a Nova body ???..... NO
Ford 9" rear end and a TH210 transmission with a Marty chance converter care if I have a Mopar Head driving it ... NO
Wheelie bars and turbos, beadlocks and spindle mounts rims and a BS3 ECU all the bells and whistles........ nope
Its all part of the package ..
The heads are actually the cheapest part of the build .

I need to take something back I said in my last post. Brandon/440 Source, doesn't really belong in the other group as, and correct me if I'm wrong, but he made parts already being produced, just cheaper. The others engineered, or paid people to engineer parts that advanced the Mopar race parts selection. I'm not saying his stuff isn't good for some applications, but not for me. JMO Uhh, we designed our Stealth cylinder head. We paid roughly the cost of a house to manufacture the tooling. Look at this head from the side, front or back and it looks like no other aftermarket head. If anything, it actually looks like a stock head which is what it is made to resemble. The chamber is 80cc's. No other aftermarket Mopar head comes with an 80cc chamber. But on Moparts, we "don't really belong in the other group" (of cylinder head manufacturers) because we "made parts already being produced, just cheaper." Who exactly was making our Stealth heads before we were? Gotta love Moparts.
