well the duster came from the factory with a slant 6 or a small block wasnt realy desiged for a big block i understand this, you need to modify it for a big block and racing applications. what i was tring to say is the chevelle came with everything from a 6 to a 454 with only only motor mount locaton differences easy cheap fix and it drives like a dream with a big block in the nose of car and im sure the b body mopars handle the weight of the big block to i had a 71 road runner 440 4 speed in high school dont remember it being nose heavy even though only drove it 2 weeks and put a rod through the side of the block doing a first to secound holesot in front of the school my fault must of over rev it, factory stuff cant handle more than 4500 to 5000 in my book. yes the duster should be faster ,but putting a big block chevy of equal horspower and a turbo 400 with a basic beef up into the chevelle would have been cheaper easier and way less stressfull project and much safer, turbo 400s are not know as the exploding transmission , hence my comment on going through all this bs to get the same results the only benifit to the duster is its lighter that is why i went with it i like things simple my fomula is the old horsepower to weight ratio, once again im not bashing mopars, its my fault i should have done more research to see what i was getting into. ive gone to far to give up now think im gonna buy the twrcp metal shield to satisfy the safty tech and im going to reinforce the factory floor and tunnel on the drivers side for my own safty. from what i understanding the problem is the factory drum is heavy and should be replaced with a billet one ? its not like everyone explodes i always do my burnouts in 2nd gear then shift out to 3rd i did this not even knowing 1st gear burnouts damage the tranny i do this to not over rev the engine. have also read of guys running 727s with factory drums with no problems for years i will take safty precautions for my safty and the safty of others and i will also open up my wallet bend over and spread for the mopar gods once again lol thats my bla bla bla for the day.
