SBC 355 BUDGET BEATER MOTOR

[BOSSMAN]

This is for a friend of mine. It's a SBC 355 on a budget. Short block consists of Stock 2-Bolt main, RPM 5140 6.00 length rods, Speed Pro Hypereutectic Flat Top pistons, and a stock reground crank all balanced. The cam is a Solid Flat Tappet (sorry not listing specs) and some 487X heads which I'm helping him port and flow. This motor is probably 425-450hp once the heads are ported. Here are some of the progress pics:
