Hemi Engines
dreracecar:
Even in aluminum the early Hemi is very heavy and take a long time to build heat. All the old swapmeet parts are gone so generally one has to buy new which is pricey.You will put thousands into an iron block a take a chance of blowing the crank out of busting out a cyl wall and have to start all over again. The one great advantage to it is---very tear down freindly, pull the heads off and not touch the magneto or re-seal the intake manifold ends, after the manifold is off its 10 studs and the heads are off, My SBC is 17 studs and thats after taking the rocker assy and headers off.
Try not to look at everthing as a loss, but as a bank account. Unless you totaly destroy it , when you are done you can sell it (VALUE) to recoupe investment, any loss from sale is considered the cost of doing business

Call Tony Lombardi....They cut their own aluminum olds...pontiac cant be that much different or harder to do.

The Chevy=Chysler mentality thing isn't as much about being in love with one brand or another, it's about parts availability. Not everyone has the time, money, patience or ability to make every little thing on their car or engine. The RED bracket racers have been the driving force in BBC development for years now, and as a result there's plenty of new and used stuff out there for reasonable money to go fast with. Same with the Hemi stuff, except its been the big dogs of the sport spearheading that development either decades ago or right now. I always get a kick out of my nostalgia customers with blown injected combo's towing to the line running 7.50's while my RED guys drive their cars up and back while running 7 flat.
That being said, I do love different combinations. But racing is expensive enough without paying extra to go just as fast as the guy next door.

So NHRA in banning the Ford from racing in all the classes it's banned in, was to save me from making parts ? So then I would go buy someone elses parts & run a Chevy or Chrysler, OK this makes real sense ? It wasn't the Chevy & Chrysler guys that told NHRA that if they didn't ban the Ford they would boycott their races. Now it all makes perfect sense. I can't run a motor made in 1958 in nostalgia fuel racing. I went to Bakersfield for the march meet & watched first round of TF, 9 cars came to the line for the 16 car field. It was OK that my Ford car was sitting home in the trailer, as I felt that I had been saved from spending money & making parts.

I did not know, completely out of it again.
NHRA banned Ford Motors?

Of all the things they may have considered when making the rules, I'm sure that keeping you from making your own parts wasn't one of them. Whats to stop you from developing Chevy or Chrysler parts that are better than whats currently available? I'm sure their line of thinking came from the experience they had over the years when guys showed up with stuff that was homebuilt, custom, or one off trick (some of these things were brilliant, some not so much) stuff. Some of these guys spent their life savings while others spent beer money. Some showed promise while others showed how well the safety safari did their job, cleaning up oil. That's not saying your stuff wouldn't be top notch, but they won't know until you make a few dozen runs with only the same or less problems than the common combinations that they KNOW have high quality parts in them. Couple that with the fact that there's tons of info and help available for running fuel in the current combinations, and they just might be saving you from yourself. And then there's the opposite problem, what if your stuff turns out to be head and shoulders above the rest? Then they have to police the class to maintain parity (reference PSB, pro mod, and TAD) and that opens up a whole new can of worms. Unfortunately, it's not the 60's any more and if you want to play in the big leagues you've got to play by their rules.
Something to remember is that the racers themselves gravitated to these common combinations for a variety of reasons, not necessarily because the were the best engine out there. Ease of maintenance, new and used parts availability (and interchangeability) aftermarket support, availability of good used cores and parts all factored into it. I really do respect the fact that you like something different than the norm, and I think there's plenty of room to play in the slower classes and have a great time doing it. If you really want to put your Ford to the test, there's always Land Speed Racing. Radical, different, and unique engine combination are the norm over there and you'll be welcomed with open arms.
