Not quite. I could be wrong, but I think you can still buy the Mopar block from Chrysler. I know you could just a few years ago.
Just FYI....The fuel blocks are Brad Anderson or TFX...They are derived in theory from the Hemi, but theory is about as far as it goes...lol
Also, its the same for the Heads, and there are only a couple places that make the fuel cranks...Most teams use Sonny Bryant cranks at $3400+ per piece...
I think that Ford, Chevy and Toyota should ALL come up with their own parts...It is part of what helped grow NASCAR...These manufacturers want to win, and they will spend a ton of $$$$ to do it...
The average NASCAR NNC team receives $2,000,000+ cash and also engineering support & sheet metal....They also spend a bunch on the telecasts, the races, awards, etc...?
Would you be surprised that the most that the manufacturers have done in the fuel ranks in the last 10 years was giving a handful of teams the Chevrolet Monte Carlo bodies, and even fewer teams were given the Impala bodies...No parts, vehicles, or cash for anybody but Pro Stock, and even there, the manufacturers don't spend much at all....I'd bet that Fred Simmons from GM Racing has LESS than $2,00,000 for the
whole series, let alone one team....Bet on it...
