I currently building a 406 with a 4340 forged scat rotating assembly and a set of 195 AFR heads. It will go in a swb Chevy stepside. I started building the 383 stroker and mid stream changed it for the bigger cubes. I got the DART SHP block 31161211 thru summit racing on special financing. 12 months NO INTEREST plus tax-free. This set up is a bullet proof street ride. It will be transferring the power through TKO600 to set of 4.56 gears. Man I can't wait to cruise it to the local hamburger joint where hot rodders hang out. You can get this same block already to go on Ebay through tim allen motorsports.
