I ahve a stock 307 in my Chevelle. I would like to hear cam and other items you have in your 307. Still thinking if I should rebuild it or put in a 350. Thanks,
I dont know, bought a 307 out of a junkyard, put in in a 75 ventura in place of the 6-banger, was really quick, then when the ventura got t-boned a week later, I stuck the 307 in a 36 chevy,still quick.Then yanked it out of the 36 since my driver(70 chevy full sized wagon) needed an engine, that was totaled 2 weeks later by my brother(not hurt).Then we threw the same 307 into his 69 chevelle,in front of a fairbanks ******,he proceeded to beat the **** out of it for a year until he finally blew the engine. So, all in all, if it runs good just throw it in and enjoy it, and build another engine in the mean time!
Take the crank out of the 307 and install it in a 350 block with 327 pistons and a set of 4-barrel 305 heads. = A very cool combo!
It really depends (IMHO) what you plan to do with the car. 307s are good little engines and often overlooked; you used to be able to buy them for next to nothing. From that aspect, especially in a lightweight car, they work very well, and they respond to performance mods just like any other first-gen SBC. There used to be a T-bucket ('gl***) around here in the late '70s/early '80s which was a basically stock 307 with a mild cam, sidepipe headers, and one of those Summit tunnel ram packages with the twin Holley 450s. It was impressive as hell for what it was, and cost about nothing to build. However, I'd look at it from your point of view. ***uming you are talking about the Chevelle in your avatar, or something similar, those weigh around 3600-3700 lbs...in other words, a lot. If it was mine, and I needed to rebuild it anyway, I would probably look at building a 350, or, more likely, a 383 or 400. The cost to build one will be little more than rebuilding the 307, but you have a lot more torque to be gained, most parts being equal. One other thing to consider is that, if you want a lot of power, only cast pistons are available for the 307 (unless you want to pay $$ for custom pistons); and the bore size tends to shroud the intake valve. All this really depends on (1) how much money do you want to spend; (2) what do you expect the car to do; (3) whether mileage is an issue; (4) what kind of shape the 307 is in; (5) how much money do you want to spend.
We don't do Chevelles here.... or Rat Rods.. Yeah I read your intro. Read and figure what this place is about. I'm sure there are some great Chevelle sites, just this ain't one of them.
I know this isn't a Chevelle site but I was asking more for 307 info. I thought I had read on here that some guys had 307's so I thought it might be a good place to ask. Sorry about the rat rod thing too. I guess this is not the place to make any mistakes. Once again my deepest apologies. By not having an older car I was not up on the lingo and had just went with what I had heard. I probably should have stayed in the shadows a little longer huh? Thanks for the help I did get.
Then do a search, you'd get Fat Hack's thread... http://www.jalopyjournal.com/forum/showthread.php?t=45615 lot's of 307 tech in there...
this isn't a Chevelle thread, it's a 307 thread. people who don't go through life in search of negativity will see that... others won't.
wah wah wah.. Hell I even went back and looked at what he had posted earlier. And look at the name. And the first post. Wow, it sure seems like it's a 307 Chevelle thread, at least I gave him the link to the best 307 thread on here. Get over it already.
I been over you being annoying for a long time. I just don't want a new guy to think we are all like that.
Like I said wah wah wah... quit your crying already. At least I gave him some help as well. Instead of all that kumbaya ****.
and back on topic. it would take alot to make a 307 perform well. good set of heads, better pistons, cam and intake. not saying it cant be done, but you could get a 350 crate motor for probably the same money you would spend building up the 307 and get more hp and torque. after all, thats what your after isnt it? price it out, shop around for heads, cam, intake, machine work, then price a crate motor from summit or jegs to give an idea of cost.
kumbaya my lord, kumbaya.... Scott you are such a jerk sometimes......but you knew that already. Take your pills!
haha... about the 307... never had a 307 in anything, but had a buddy who slowly ***embled mild heads, intake/carb, headers, etc. on his 307 to wake it up while he built a more rowdy 350 on a stand... he got to enjoy a better performing 307 while he saved, built, etc... then swapped in the 350 and had what he wanted, without really wasting the money on making the 307 something it wasn't.
I had a 307 in my 73 Nova. It ran pretty good, for a old stock mill, in a kid's car. From what I researched, the 307 blocks are pretty unwanted for a few reasons: They are a non alloy block. No nickel, for good wear properties. No tin for even cooling. Not enough meat to punch out a big bore. Small bore, large journal crank. About all you could do, is get a large journal 3" stroke crank & make a large journal 283. Kinda self defeating, in this crate motor world we live in.
This is the sound of my Chevelle. It have a 307 whith 58cc heads from a 305, edelbrock 600 cfm, preformer RPM manifold, headers and 2,5" flowmaster, comp cam XE262H cam. The block have never been out of the car. http://www.youtube.com/watch?v=2KIJ7vctBtM&feature=related
the 307 gets a bad rap like the 305. There both still sbc engines that you can run good. The real draw back to the 307 is the heads. All 307s were 2 bbl engines that had small ***bustion chambers but also had small valves. Alittle head work or even a 283 power pack head or maybe even the 305 HO heads would help make the 307 run much better. As far as cam, that depends on what you want to do with it. I'd use a 268 or 274 with about 450 or so lift, dualplane intake and a 500-600 carb. and just run it. just my .02
I almost agree Deuces BUT we built a 307 actually 310cu in (.030 over) using a small journal steel 327 crank and 305 heads w/ I think 1.88 intakes and a comp hydraulic cam very mild an Edelbrock performer and stock dual exhaust manifolds in a 68 Chevelle wagon and got 24 mpg. had some balls and I wasn't always working on it. Didn't overheat and could run 2500 rpm all day with 3.50 something gears. Guy is still driving the **** out of it. IMO build a good small journal 307 if ya got one.
The intake valve size on the 4-bbl 305 heads are 1.84's... Same valve size as the Ford GT-40 iron heads.. The '76 and '77 305 heads I've got have the small 57 or 58 cc chambers which would be great for the combo I had listed earlier.... And they're cheap! A little port matching and some bowl cleanup is all they need.
Got a standard bore 1970 307 along with early 60's 282 Power Pac heads.The pan is still on the engine,turns over no problem.Been for sale for 6 months for chump change,no takers.You guys who like 307's come and take it away for 20 bucks
