Link You can go to the above site and do a search. This is hands down the best Chevy/GMC Truck forum on the web. THIS CAN BE DONE WITH YOU CURRENT COMPUTER(ECM)! What I have done/in the process of doing, on my 93 Chevy truck..... .. Caprice crate engine-a little more compression and stronger bottom end than the stock truck engine. Available at paceparts.com for under $1700. Then swap out the cam with something a little more truck friendly. Swap the heads too with the Vortech heads. You will have to get a different intake manifold as well to fit the Vortech heads, you can either get the one from GM where your Throttle body bolts right on, or for better breathing you can get a carberator type intake and an adapter for you throttle body. If you need to keep your EGR valve for emmision purposes, you will need the GM intake and the EGR kit, if not, simply do away with the EGR equipment and when all is said and done, have the egr also removed from the computer programming. This should all be good for 50+ horsepower,75ft-lbs Torque, and better gas milage too. If this all seems crazy, its not as bad as it first comes off. Getting a new chip is as easy as plugging in some type of computer scanner and sending the values to someone to make you a new chip. Hope this all helps, Jim
