I truck pull, the club is debating a rule change from allowing iron only heads to allowing alum. This definatly open options for me but how do mopars compare to the other 2 on a 470 ci limit engine I have herd Fords can make 1000-1100 hp at 9000 rpm on the a460 heads and sure GM has many options. I am looking for some input if its possible to build something along these lines that will live for 30-40 hooks and a thought of cost to build. general eng rules no hemi heads,single carb, no sheet metal int. upright headers allowed. Im thinking this class is going to get out of my budget if alum. is allowed. Thanks for any input

If the class you're pulling in is anything like the class around here,,it is ALREADY out of budget/hand!! When you srart talking 1000+ HP and 9000 RPM....thats not budget-minded pulling!! I believe that is why the diesel classes are so popular now.
If you like drag racing, support your local track.

my budget is lower than many that i pull with but i guess im just looking for some solid input on what kind of money it will cost before i vote for or against this rule change looking for some real numbers for hp and durability because power dont always get you the furthest down the track

aluminum heads will be the begining of the end of "budget" programs. Head work is Expensive and Effective. But Iron heads limit the amount of Expensive (head) work that can be done.

Is it a one ton driveline class or Profab/rockwell class?
If it is a one ton class, and everyone goes out and buys aluminium heads, and cams to go with it, driveline failures will get very common. Then guys will get tired of wrenching on the trucks. Then you will start talking about Profabs and Rockwells.
I can see both sides of the coin. If the Ford and Dodge guys can buy new heads, and not have to use 1960's technology and castings, there should be more completitive Fords and Dodges. BUT here's the catch, what are they relying on to limit power? Cubes, CFM, Driveline? If they are relying on driveline to limit power, it will likely end in less trucks. Guys get tired of breaking something every weekend.

That's a good thing because you'll be hard pressed to get any life out of a stock block making 1000 hp .

If you want to stay competive 
I know several drag racers that used the original B1 on small C.I.(under 450 C.I.) motors that ran with the best of the other brands in the nation on a heads up basis
