Good looking truck Peach... I'm looking for one right now to put one of my spare motors in. Ive got a little 355 sbc dyno @ 515hp. I like those all the way to 72 model.
355 with 515 is a high dollar sum biotch... Mine has a 428 small block with aluminum darts, big motha thumpa roller, 11.5/1 comp. 4l80e tranny with a 10" hughes verter. Figure my shcrap box is makin maybe 500-550.. She runs better than most street rides around here
