hello to everybody. for the past ten years i have built plenty of sbc's with my father in the back yard,keep in mind im 25 now, and by now the understanding for them come really easy for me. 2 years ago i traded a 86 grand national to a 1940 chevy with a 230 inline. my goal was to take the inline 6 out and replace it with a 383 untill one of my uncles said "you see v8's everywhere, why not try to make power out of your inline 6" after he said that... my mind changed. so now im starting the learning curve. i have done some research, and orded the power manuel by leo(yesterday) and am wanting some advice. here is what im working with: 1940 chevy cab with a 1929 ford bed sitting on a s10 frame, stock 4cylinder rearend(373 gear i think)with a stock 230 out of a 1965 gmc van or chevy van not sure with a th350 behind it. truck weights 2560 with me in it. tires in the rear are 28" tall hoosier street tires.ok for the first question what is the best way to start adding some hp without tearing in to the gutz of the motor?(bolt ons) and what can i expect as far as gains.i found a good deal on a 292 that came out of a 80s one ton for 100 bucks, this is whats replacing the 230. 292 will be a brand new motor.(except for block and head)and i would like to know what is the max hp and tq i can get out of this motor with stock style head.(i will put lump ports in it). my goal here is to make a prostreet inline 6 ratrod that will be drivin a lot and might go down the track a few times just to see what she has. thanks in advance mike
