I have a 69 malibu with a 307. Is there a way I can build this motor to make it fast and durable at the same time? Will I need a new crank, new heads, borred block, what cam do I use? These questions and more. A machinist told me that I can use 327 stuff, I'm new at this but am willing to learn and ready to get started. Or should I just build a 350? Will someone that honestly knows what they're talking about please help!! THANKS.

Hello yes i think 307 are good engines i built one n put a 350hp 327 cam n new steel timing chain n gear in it and put a pair of small cc 305 heads on it that i ground out a lil ...n a quadrajet 4 barrel that a friend rebuilt on it she was a demon in my lil '78 monte carlo with 2.73 posi rear it just never ran out of power in high gear n could come off the line like you not believe for so few cubes idk about a 68 cuz i not sure about weight dif. But es a 307 can scream nothin like the sound out of dual exhaust with blanks n no cats5

307 has same stroke as a 327 if you are not aware of that so a 307 crank will go in a 327 or vice versa long as its large journal im not sure on that but i think all 307 are large journal
