Just finished a nice little 350 sb for a guy with a 79 vet. He is keeping it mostly stock so the choice was easy. Started with a late model vortec block set up with a roller cam and went for their. Made it a 9.2-1 compression and used the GM 383 cam. Did a copy of their 350 ram jet motor except it will be a carbed set up. Did one for a guy two years ago and its in a 79 Malibu with a stock converter th350 trans and a 3.50 9inch for rear gear. Nice bracket car, runs very low 13 at 103mph. and gets 17mpg with a 600cfm carb.
