I bought an old tore apart 70 camaro that was supposed to have a 327 in it, well after running the #s it turned out to be a chevy 307 .
I havent opened it up yet but believe it has had some work done to it.
Any way has anyone got any experience with or opinions on chevy 307 and is it worth putting money in to.
Thanks
Well.......the only complaint I have with mine is that it just doesn't have enough cubes for the power that I can get out of a 350.
For the same money your going to put into that rebuild- I'd pick up a 350 short block, and a decent set of heads.
Hang on to that crank, and heads.........they make great trading stock.
get a 283 :D ................scooter
You know Gasser, I am a Ford man. But back in the late 70's early 80's I owned a Chevelle with a 307 and (in my earlier life many 283's) and I rather build a 307 than a 283 cause of the longer stroke. With the same basic modes the 307 puts out a lot more torque and about the same HP.

GEE Scooter.......your vast amount of personal HANDS-ON experience with 307s (or any engine) is based on....????
What Oldf100fordman and hambiskit said is right on.
The 307s were a good get around motor especially in something reasonably heavy. The long stroke makes for very good torque. They respond to all the hop-ups that any SBC responds to and as a rugged as the rest of the engine family. No they don't wind up like a 283, but put in a realatively heavy car with highway gears and tall tires and their no ball of fire either.
Basically waht we really need to know is what Cool Runnin has in mind for the motor before any realistic suggestions can be made.
Ahh but what do we know we've only actually build, owned and driven 307s
:LOL: :LOL: :LOL: :LOL:
Thanks for replys
To answer a question of what i have in mind is
To start I have replaced the front and rear end well almost the front end is underneath waiting for final adjustments before I bolt it in.
I do of course want HORSE POWER but along way to go until finish product and I figure i have the 307
I could try to work out trade or sell and get 350
You might not wanna put some work into it, but we used to run dirt race cars. 355 cube rule and 512 lift rule. What we did with a motor at the beginning of a season was build a 331 stroker, the 350 crank dropped right in, only diff being the berrings. And I said 355 rule, well I could point out 5 guys running 400's, but track politics wouldn't DQ them . BUT After spending weeks in the tech lane after winning a few features or at least coming in the top 3 and being on top of points they were amazed at what the numbers were coming up as. I even got a cuber for free after they threw it away thinking it was wrong. You would be surprised what you can do with one. Wouldn't you rather beat a 350 saying it's only a 307.... a little more pride in that, I know I get bigger smiles from doing this then knowing I out match someones motors cubes.
:mad: i had a 307 biggest p.o.s ever so i HAVE built at least one.dont start pulling the age thing back out but there are ways u can build them i just dont prefer them so if i came on offensive that WAS NOT my intent:p .......scooter
you could always bore it .125 over and make a 327:p ....scooter
well they say you learn somthing new everyday.! so would it hurt to bore a 307 125 and make it a 327??? or would that be to thin???
What year was your 307? Remember, there are two incarnations of the V8 307. The old school chebby 307 made from a 283 crank and a 327 block(right?) and the 80s 307 Olds. The Oldsmobile motor Does Not respond well to the traditional rules of SBC mods. You sure thats not the motor you had?Quote:

Had a 70 Chevy c10 with a 307ci. Ran like a bat outta hell and never had one problem.
I had a 71 camaro with a 307,added duel exhaust, cam , and a4bbl intake with a quadrajet,Run really strong!
ok i screwed up my fault LOL it was a 305 yes i screwed up dont be to rough on me lol hey i forget things to ya know 17 is mighty old :LOL: i feel like a geezer..........scooter p.s sorry for causing trouble lol
305 isnt even close to a great Chevy motor. So, you messed up. It happens. Now, lets do Stuff!

I am pretty sure it is an early 70s model.
Did you say that would be better?
Then chances are its a 305 or Late 307.
Odd, but maybe you just got a lemon. It happens.
'70 Camaros came with 307's and if the numbers say that's what it is, it might be the original motor. From the numbers you should be able to tell what year it is. As CFS said you could build it as a torque motor, or follow other suggestions and spend the money on a 350.

or a 283 or a 327 or a 400 lol.......scooter............
THERE ARE MORE CHOICES THEN JUST 350 LOL:LOL: **)
HEy I got a 307 in my 1986 Cutlass Salon and let me tell you if you have a light body that hog will scoot. mine will hit 110 in a quater mile completely stock
How long is a quater mile??????
Howdy all;
I've got an engine that I took out of my old 68 chevy Impala before it went to the great beyond. What I need to do is verify the engine #s to make sure that it is what I believe it to be, which is a 307. Were on the web can I look up engine #'s for GM engines?

The chebby 307 had the 283 bore and a 327 stroke. A 327 block and a 283 crank would give you a 302.Quote:

It is the old incarnation, with the 283 block and the 327 crank, according to the numbers on the engine for 1968.
Thank for posting the classic truck restoration web site, I was able to track down the spec's on this engine also.
:D
oops, switch that around... lols... bore of the 283 and the stroke of the 327..
U said there was some work done to the engine?could be 327 c.i. but a 305 or 307 block ,what work was done to the engine ?and does it run ?if u tear it apart check all the numbers u can find ,kinda like treasure hunt fer whats been done it might already be a screamer and whats junk about the 305 ?other than its not a 454?some balancing and mild head work a intake, carb, cam and headers it will pull nice around 5500 rpms slap a stick behind it and u got a runner.screw in rocker studs a girdle and some main support and u can wind the thing up like a 4 cyl
I am positive the block is 307 but it has been sitting a while.
It was in a 70 camaro someone started on and didnt finish.
I noticed someones ss# stamped on the block and it has been painted .
I had to fill the block up with oil to loosen the crank but it freed up real nice. Now I got to put new plugs and distributor to se if I can get it to fire.
If not, I will take it apart like you said.
Right now I am In the process of installing a front suspension which I found a pretty intersting way I think to do it. I will post later and let you know how it turns out.
I figure I have this winter to finish suspension, motor and new wiring.
Thanks for replys
I found this site to be one of the best pit crews a guy could have
Hey streets, I object! It is possible to get a 307 Olds to do 110. Not in stock form, and definatly not in the 1/4 mile, but its doable. Give this a look;)http://www.mondellotwister.com/ArtGiantK.htm
MY OLDER MECHANIC BROTHER IN HIS INFINIT WISDOM BORED A 283 OUT TO A 292..... WHEN THE SMOG REGULATIONS NAILED HIM. HE HAD TO TEAR IT ALL DOWN TO CHANGE THE TOP END OUT, WHEN IT PASSED TESTING AND WAS REINSURED FOR THE YEAR WE TORE IT DOWN AGAIN AND PUT IT ALL BACK THE WAY IT WAS, SO HE COULD OUT RUSTANG HUNTING AS HE PUT IT ,, AS I WAS HELPING HIM HE DECIDED TO TAKE A MEASUREMENT AND RELIZED HE HAD ENOUGH THERE TO GO A LITTLE FARTHER... HE ESTIMATED HE COULD GET AWAY WITH A 350 OUT OF THE BLOCK,BUT SAID THAT WOULD PROBABLY PUSH THE JACKETS TO THE LIMIT I THINK HE SAID, SO HE FIGURED IF IT WAS BORED OUT AGAIN 327 WAS THE CHOICE TO GO WITH.... SO IF THATS ANY INDICATION MAYBE A 307 CAN BE TWEAKED ENOUGH TO GO LIKE A BAT OUTTA HELL LIKE THAT 292 DOES IN HIS 80 CAMARO....EVEN IF THE STROKE IS LONGER...
BUT THEN AGAIN WHAT DO I KNOW I JUST PLAY WITH THE 350'S ANYWAY !!!!! :D
