Thread: What to do with a 307

Tweet

I've got a 307 I pulled from my truck. What can be done with these odd monsters to make them better.

replace them with a 350??? is it an Olds or a Chevy? there's not much that can be done. you'v got the job half done anyway.

Its a chevy. I just hate to waste it. It might get replaced with a 327 that I have most of the parts for ( That means it will not cost as much) As for the boat anchor I will have to find a Ford . my 53 Wagon is powerd by a 360Mopar This ones for My 51-55 Willys PU

It's not a good foundation for a hot rod motor, but there is nothing wrong with it as a motivator for a street car/truck. Do a down and dirty rebuild on it and run it. Just don't spend a lot of money on it.

you could bore it .125 over and custom make a 283 lrg journal crank <307=283 with 327 crank. 302=327 with 283 crank just clarifying >

Keep the crank. It's a large journal 327.

There was just recently (within the last few months) an article in one of the rod magazines on a 307 build; cost about average for a little block build, and they got something like 320 ponies out of a fairly mild builup. If I can find the mag, I'll post it so you can look the article up on-line.

i'd have to recommend flower pot, with a nice paint job, might look nice setting on the porch with a few pepper plants

One of my Chevy bigot friends insists that, if you keep the limitations in mind, the 307 isn't a bad engine. I liked the post about an article on a 320HP build - but it isn't going to be a 350, no matter what you do with it. Good luck!

ah its a daily driver motor. we used to have a 79 malibu wagon with a 305 dependable as hell it was. BUT it wasnt not hot rod. even though it was lowered with chrome wheels and a street scoop when we got bored we smacked a 142 weiand supercharger on it it was fun.

Large journal 307 crank,right? Put it in a 350 block,4"bore,5.7 rods,equals a 327,or am I too drunk to add? With 350 piston,flat top or domed,shouldn't be too shabby??? Vortec heads,solid cam,oh,oh,,,shut up
OOPS,forgot about that lift limitation on those heads,,,,no more drinking and motor building for me!lol Or do they make solid cams that low?

It's a large journal 327 crank. Put in it any large journal 4" block with 327 pistons...and voila a 327.

OOPS again,correct MI2600, with 3.25 stroke a 327 piston.
