Technical 307ci pulley alignment issue

I have 63 impala station wagon that somebody put sbc 307 in it. I have just rebuilt the motor, the casting numbers come back to 70-73 camaro engine. I replaced the crank and now i cant get any of the pulleys to line up. I have a couple spacers, im ***uming for the p.s. pump but i dont remember where they go. Can anyone help? Also the new crank is threaded on the end for im ***uming holding the harmonic balancer on but the last crank did nothave that.

 

Is the damper all the way on? It takes a lot of force to press it onto the crankshaft, there is a tool for that purpose, it threads into the hole in the crank, and has a large threaded shaft with a nut to pull the damper on.

If that's not the problem, then I expect we'll need to see pictures of what you have, to help you figure it out.

 

The damper is on all the way which makes the alignment issue worse. i have some spacers that look to go on the power steering pump but im not sure where they go and if it takes more than one.

 

Lost me with spacers as in, to far in??? Can you post pictures?

 

Pictures would help but if putting the dampener all the way on made things worse I’ll ask which water pump do you have? Are you using the short pump as would be stock in a ‘63? The 307 originally had a long pump, if that is used then the ps pump and alternator will be too far back.
Keep in mind that you cannot mix and match, the short and long pumps have different length pulleys on the pump and the crank, the ps bracket and alternator bracket will be different too.

 

When you get some pictures up, I'll come back and play.

 

I will post pics later, as i am at work. The car is a 63 impala but the motor is out of a 1970-73 camaro or thats what the casting numbers tell me. I rebuilt the motor and put a new crank in. But i bought the wrong water pump for it so it has the previous water pump on it that was on there before the rebuild, same power steering pump and i upgraded the alternator to a 100 amp alternator but the mounting and depth of the alternator is the same.

 

When you post pictures, we can see if it's 63 impala stuff you're working with, or 70s camaro stuff. They are quite different. Lots of guessing involved until then.

 

307 - I really like that engine and it is so underappreciated. People always confuse it with the 305....ugh.

 

Did your belts and pulleys lineup before the rebuild? Did you swap water pumps?? If it's not the same water pump maybe you have the Corvette water pump which has a different spacing.

 

Kevin but back the original water pump and is still having issues.

 

It has the original water pump, it was never changed because i ordered the wrong one.

 

have a stock one in an el camino rated at 200 hp (w/ 2bbl & auto) and am always surprised at how peppy it seems. I've had worse 350's.

 

283 + .250 stroke = 307, 1968
327 + .230 stroke = 350 , 1967

 

Let's skip the c.i.d. math history and stay on topic.

 

Had a 307 in an OT Nova and was not impressed. Not peppy or a strong puller. Had stronger 283s and 327s for sure.

 

So this is the 610 cubic inch SBC V-16 I've never heard of?

 

Ah, the poor maligned 307. I had one in a 69
C-20, with a four speed and 4.57 gears. Pulled my bracket car easily. Stopping, not so much. Is the alignment issue with the crankshaft pulley only? Did you use the same damper?

 

We'll never know if we don't get some kind of visual... Dammit Man, we NEED pic's!!!

 

Here's a picture of my 307, just so we can say we seen a picture of a 307 ha ha

 

Yeah I got a chuckle out of that post too.

 

Since this isa 63 Impala I'm ***uming that you have a short water pump,the later 307's typically had a long water pump,but that's beside the point since they are interchangeable provided you keep everything together,ie. SWP pulleys and brackets or LWP pulleys and brackets. If it is a case of the crank and P/S pulleys lining up and the water pump pulley not lining up with them it could be a case of the water pump pulley mounting flange being pressed on to the water pump shaft either too far or not far enough,if its too far it can be fixed by using the water pump pulley shims, if its not far enough it will require pressing the flange farther onto the pump shaft,otherwise you will be shimming everything out to line up with it.

 

I see your point of view and rational.

 

I don’t understand how the original 307 crank didn’t have a front bolt in it ?
These engines were made in late 60 s,,,,,,all were bolted on by then .

Also,,,,,is the alignment problem with the water pump pulley,,,,,or the steering pump pulley ?
Sounds like he keeps mentioning the steering pump,,,,,,which should rule out the balancer location.
Like everyone is saying,,,,pics will help a lot .

Would be interested in knowing which pulleys don't line up? It sounds like the power steering doesn't line up at the lest. But does the balancer pulley line up with the water pump pulley, alternator, or anything?
There are numerous different pulleys and mounting brackets for SBC, so it's possible to make almost any combination to make things all line up. I've never run into the issue of different crank snout lengths. I have run into different crank snout diameters that required different harmonic balancers.

 

The 307 in my 69 Chevelle (sold Oct 68) came with out it. I was given a later 307 and that one was.

 

My guess is he used a 327 crank, that would explain everything

 

Oh Brother

 

Hey Johnny ,
That’s interesting to hear,,,,,,I’ve never heard of that being missing in 69 .
You learn something new everyday .

Not uncommon on the low-perf engines in that era.
