Dave,
Well this is the reason I am going with a supercharged engine, I can have like a 5 psi pulley on it for 500 to 600 hp and if I decide to I can go up to 10 or 12 psi if I want to run it from time to time. I want it to be for going to car shows and possible the Hot Rod power tour. I want a big displacement motor with a 5-speed trans and a supercharger so I can puts around without even creating boost, but have it when I want it, Is that too much to ask for, haha.
I understand it is going to probably cost arount $10,000 to $15,000 for the engine but thats fine, if it takes 5 years I could care less, I want this car the way I have dreamed it to be.
My uncle just finished his 1971 dodge Demon with a 340 stroked to like a 380 with about 500hp and a torque flight 727. It is a rough ride, but nice. I just don't want to have 12.1 to 1 compression and a rough idle. Thats why I like the 5-speed and a supercharger, I can have a easy idle cam with a supercharger and still make great power.

I am open to any suggestions and comments, reality checks are very welcome.
