Starting 340 Build w/ Supercharger

Okay, so out with the stroker kit. I'll probably stay at around 6-8 lbs of boost TBH. I do have an 8 3/4 rear, but with 3.93 gears. New forged pistons with H-Beam rods is doable. I was looking into changing out the leaf springs for a spring system, is this what you're talking about when you say SS springs? I may also do a roll cage to stiffen the chassis as well. Do you recommend any specific manufacturer for the cam you're talking about? Now, forgive my naive-ness, but when you TC, you're referring to a torque converter right? I want to do a manual swap, over to a TKO 600, so as far as I know, a TC wouldn't be necessary right?

Okay, SS springs mean Super Stock leaf springs. On a Duster/Demon you would want the 002 and 003 springs. You will know that means when you research them. Mancini Racing sells them. The roll cage may or may not be a good idea depending on your level to put up with discomfort. On a street car a cage is a pita because you get in and out so much. On a race car it is a must. I don't say one manufacturer is better than any other but who specs the cam could make a difference. I went with Steve Morris Racing to spec and order my cam because they specialize in boosted engines. Cost a little more but worth it. Correct on the TC meaning converter. The thing you have to remember with a roots blown engine is the torque is there instantly. You put your foot into it and the acceleration is instantaneous, there is no waiting for boost to build. Take that into account when you choose your tranny system. As far as mileage goes, most people that build a blower engine are not to worried about it but for comparison purposes, when I am just cruising the highway at 65 mph I get 14 mpg. Tires are 275/60/15's and 3.23 gears with the stock gears in the 727 tranny I have. That is with twin 600 holley dbl pumpers on top of the 6-71.
