68 ss leaf springs

From the factory would a 68 SS come with 5 leaves or possibly 2? It has 2 leaves. It would have been a 12 bolt correct? Could it be a 3:42 ratio from factory? Would the 350 be a 4 bolt main engine? Could 12” wide tread tires go in the back of the car without being tubbed? Thanks, Had a conversation with the owner of this car and the above items were mentioned to me.

Re: 68 ss leaf springs

I dont think 4 bolt main caps were used until 1969 as a rpo and then only in the 302. The 350 got them in 1970 I think.

Re: 68 ss leaf springs

Was told this is the original engine for the car. Also that it was 4 bolt. I just do not know which was correct.

SoCal Tom thanks for the reply. Was told it was 2 leaves. Could three leaves have been removed. Did 5 leaves ride really stiff?

Re: 68 ss leaf springs

Check the numbers on the block. That will tell you if its original. I dont believe its possible that you have an original 4 bolt main block. Some of the early 69Z's didnt have them.
Dunno about 12's in a 68 either. Enough air in the shocks and you could get anything under them, but in, with wheelwell trim doesnt work in a 67 assuming tread width and not section width.

Re: 68 ss leaf springs

12" wide tires could fit _ON_ a '68, but they won't fit _UNDER_ a '68 unless it's mini-tubbed. When I say "ON" if the suspension/tubs are stock... there's probably 2-1/2" (or more) sticking out past the fender. Some people think that's "real period" as more than a few people did run ridiculously wide tires back in the '60's and '70's. I'm not a big fan of that look, and it usually means the rear is raised high enough so that the tires don't hit during travel up and down.

Get yourself a picture, it's pretty ugly (JMHO).

Re: 68 ss leaf springs

All SS had a 12 bolt rear.
3.42 wasn't a factory ratio. 3.31 or 3.55 was the closest
Most likely 5 leaf, although 4 is possible.
None of the small blocks had 4 bolt mains in 68

12" tires....no...the inner wheel well to fender lip is only 11" (unless they stick out the wheel well--not a factory thing)

Re: 68 ss leaf springs

If you want to determine if the rear end is original or not, then you need to be looking at the casting date on the center pumpkin and the stamped code on the right side axle tube. Leaf springs get changed out over the years. Nothing came from the factory with 2 springs.

Re: 68 ss leaf springs

57Vette thanks for your reply. Can you look in the trunk and visually tell if the car is minitubbed? I am thinking it would stand out to me. I looked at your link of the car with the wide tires and it is pretty high up.

Re: 68 ss leaf springs

3D cad, would I be looking for the engine no. at the rear of engine on drivers side or the no. at the front of the engine on the passenger side. I agree about the car engine not being a 4 bolt engine if it is indeed the original to the car. Thanks I will inquire to the owner if he has a picture of the engine no.

Re: 68 ss leaf springs

Well, since it's been nearly 10 hrs and no reply from Steve, I'll attempt to answer....

The stamped codes at the front, pass. side will determine if the engine block is original as beginning in 68, all engines had a partial VIN stamp which would match the cars VIN if original. The suffix code will determine what engine (327,350, AT, MT, etc) it is/was.

Here's more info.1967-69 Camaro Drivetrain Decoding If it checks out favorably and you're still interested, then the other codes (casting numbers and date) should be checked as well. Not to mention a pic pad stamp to confirm it's authenticity.
