    So I was talking with my friend that is a mechanic and he said if you really want a fast truck with allot of HP go find a used cyclone. I have never heard of a cyclone, we got online and found some video's on u tube and apparently it is the fastest "stock" truck built.... even beating the ford lightening trucks which come in second in speed records.

    Now I am not into the 70's and 80's body styles and I like my full size truck and not a mini truck; and I know allot of us love to mod our trucks,

    SO the question is....... What would it take to give a Silverado or Siera 1500 the same or better performance as the cyclone had....

    The 0-60, the one mile.... etc. I understand that this means allot of upgrades.... prob. replacing the diff, axles, transmission, all the manifolds, lowering the truck between 1-3 inches, re-programing/tuning, etc....

    What would a parts list be for this type of build out? and if we could break it out into 1) least expensive build 2) moderately expensive build and 3) the premium upgrades for the best build.

    Kind of hard to beat an AWD turbo 6 in that chassis.

    IMHO, the amount of money needed to make a silverado comparable you would be able to buy a used Syclone or Typhoon. Otherwise, a lot of suspension, motor, tuning would be required......not to mention a nice sized turbo.

    They were a great GMC truck. They also made the GMC Typhoon that was a nice package also.

    Nak the problem is the big difference in weight between the S-10 and the 1500's would be the biggest issue. I bet if you put a big enough turbo on the 5.3 you could get what you want. I would agree you would have to drop the level of the truck a few inches. I would also say maybe a gear change depending on what you got in the truck. It would be nice if the general came out with a truck like that.

    Yep the Jimmy is what i was refering to, i forgot about the truck model however since they are so rare. As to making it that fast, i personally think you could make the 5.3L put out more power (once again though the power to weight ratio is the issue here) you will want to go with a super charger. I am not a fan of a turbo in that large of a truck due to the lag that you dont want off the line with that much weight. a good cam, bigger injectors, I would put in better head and intake gaskets and a blower putting 10PSI should net you the range of power that you want. a good tune to match the blower with the power train (the 4L65E will need to be built to take the power or that will grenade at its first oportunity) i agree with the rear gears anything less than 3.73s will not give you the desired results. but a bottom line build will be at least $10K.
