307 Pistons
Anyone know the availability on 307 pistons and possibly bored over pistons?
Also if anyone could give me a price estimate or a place to buy? Thanks Pat |

Re: 307 Pistons
307 stuff is still out there, they are not rare by any means. Parts should be available in nearly any city.
I don't know if I would spend a bunch of money rebuilding one though? The cost at the machine shop is going to be the same reguardless of the engine size, so unless you are trying to keep a "numbers matching" restoration? You can get more bang for you buck from a 350.

Re: 307 Pistons
It may not be sitting on the shelf at your local parts house but it is out there.
I guess the first question should be, do you need standard or oversize? rock auto shows them but they are special order TC1737 The O'Rieley chain of sotrs shows them for about 12 dollars more ea on line so shopping around may save a bit of cash. Here is a deal on Ebay that may be hard to beat. the whole engine kit and you pick the piston and bearing sizes. http://cgi.ebay.com/ebaymotors/Chevr...Q5fAccessories You might check www.northernautoparts.com for a similar kit. |

Re: 307 Pistons
I went and checked Northern auto parts
http://www.northernautoparts.com/Pro...?ProductId=627 It would come out about the same with frieght and I have been satisfied with everything they sold me. There are also a set of standard pistons with rings and a set of .060 over pistons with rings on Ebay for 145.00 http://shop.ebay.com/?_from=R40&_trk...All-Categories As the guys said, they are out there you just have to hunt for them. |

Re: 307 Pistons
I managed to find some at my local auto store. A guy told me that they would be hard to find but i had no problems, and they arent that much more money either. They said they could get them .020, .030, and .060 over. Im thinking .030 over.

Re: 307 Pistons
307 crankshaft plus a 350 block equals a 327, one of the finest engines to ever spin a tire.

Re: 307 Pistons
bah....still a short stroke motor.....
a 327 is like the chevy v8 version of a honda 4 banger. torque is more important than horsepower in a truck. give me a 305 or 350 with a stroker crank any day in a truck. my "new" 72 burb 3/4 ton 2wd has the 307 and a 3 on the tree. it is geared really low and the 307 is tuned for low end power, but that won't deter me from swapping in my low mile 406sbc and getting a more highway friendly rear gear. low end pulling and cruising power is what i like! |

Re: 307 Pistons
My truck came with a 307 and I did a simple rebuild and put a set of late model 305 4 barrel heads on it with a COMP 268H cam in it. It ran very nice. Go ahead and rebuild it!

Re: 307 Pistons
That all sounds good.I`d go with what they call an RV cam.1st or 2nd step up from stock on lift.Low end torque and good hiway milage.I like the 268 idea.
Honda four-banger/327...I don`t see the ressemblence.Most Super Sports ran 327s as well as C/50s and C2s...375hp.That motor wore alot of hats.

Re: 307 Pistons
a 327 is a short stroke, whereas the 305, 350 and 400 are all long stroke motors. yes the 327 was a hi-power car in its day, but its place was on the drag strip where 6,000 rpm is expected. it makes high end horsepower i'd take a nicely built 305 over it any day in a truck where you need a more moderate powerband. i bet a 305 with a stroker crank would beat a 327 all else being equal because it would have more get up and go power. my 406 is soo sweet. like 1mpg less fuel mileage and waaaaay more power than a 350 of the same vintage. the longer the lever arm (crankshaft), the more force you are generating with the same amount of effort.
my 307 will do for now, but give a long stroke motor in a truck. and i do agree with the rv cam. my dad did a lot of trailering with his 72 suburban with a transplanted 305 (in place of the tired 350) and an rv cam. |

Re: 307 Pistons
if i wanted top end performance only, i'd buy a honda. stroker small blocks are very popular even on the drag strip. you can pull better numbers with softer gearing!

Re: 307 Pistons
I can scratch 2nd with a 307 and 3OTT, so don't let anyone tell you they are weak. I like it for the same reason guys like inline sixes, because it is a little different. Anyone can have a crate motor.

Re: 307 Pistons
I keep trying to blow up my 307 so I can rebuild it. It just won't let go. Maybe if I rebuild the Rochester 2-BBL, I can burn out my rings. It has been a great motor and I plan on keeping it.

Re: 307 Pistons
Didn't I read somewhere that a 307 is a stroked 283? I rebuilt mine just because it is the original engine to the truck and it runs and performs great!

Re: 307 Pistons
283= 3" stroke and 3 7/8" bore. 307= 3 1/4" stroke and same 3 7/8" bore. 283 is small journal whereas 307 large journal. My burb runs a 283 and sm465 4 speed. Thought about swapping it for my 454 in my truck but like my gas mileage. I just got back from a 180 mile roundtrip towing a 3500 pound trailer with the burb and averaged 13.5 mpg. However going up 6% grade I was in third gear going 35 mph.

Re: 307 Pistons
There were also large journal 283 engines at the very end of the production run. Rare for sure, but they are out there.

Re: 307 Pistons
If I am not mistaken it is like a step up from stock used in rv motors to improve torque. I am glade to hear some support for the old 307 I just did a re ring on mine with some 354-434 heads cut for 194 intake valves with a melling single pattern 218 .451 lift cam and it sounds great next I want to go with some split roller rockers 1.5 intake and 1.6 exhaust. rebuild 307s they are not anchors they are good motors for upgrading.

Re: 307 Pistons
It's not about "being like the masses". You will get more power for the money working with a 350 than you will with those small-bore engines. All of the rest of the parts are exactly the same, but you will get more from your performance parts with the bigger displacement.
