That's what I was thinking too when I saw all the parts he's talking about replacing. The extra c.i. you get by starting with a 350 will probably give you the cheapest h.p. you can get.ssal396 said:IMHO, if you are talking about a new crank, heads, pistons,& boring it out, it wouldn't cost you a whole lot more to pick up a 350 block.. Like Tom said, it's actually going to cost you LESS for the 350 parts then it would to build the 307..
Again, just my.02

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 cats5I 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.

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 journalHello 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.

Got me again😳I wonder if he ever built the 307 up seeing the thread is from 2005.
Depends on what you consider fast.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.

That was the last thing he wrote here,so it looks like he followed some good advice.At least some of these old posts are entertaining.Thanks again guys. I'll go w/ a 350!
