Modern Station Wagon

I think a Magnum would make for a really cool racecar, and the 5.7 Hemi wouldn't be bad at 345, but it would be almost 4000 lbs in its lightest class (G/SA). I doubt the 5.7 at 345 would be as good as the LS1 in a GTO at 340.

George,
Your reply made me think....I know the current GTO's did not come with a solid rear end, nor did the Corvettes yet, NHRA allows for solid rear ends to be used. I have seen both of these cars racing STK.
I wonder what the criteria is for this, location must remain the same etc.

NHRA made the change to a solid axle conversion legal several years ago. The GTO is a great example of that. I'm not sure of what the rules are on this or how the Magnum/Charger stock rears are attached, links, spring/shock set up.
One thing with the GTO was the engine was proven to be competitive at it's HP rating, where the street 5.7 hasn't been raced much under NHRA stock rules to show what it can do. I compared the engine BP specs, the 5.7 Challenger motor is quite different, street motor c.r. 10.5 to 12.7, cam lift .482/.470 to .602/.569, different heads. Some big numbers there.

Fred Lee has a really nice product that would make the IRS live if you wanted to stick with that setup.
