gears

[korndogg]

ok im tryin to find out what rear end i have (if its still stock) i looked on the pumpkin and it says .....K218....can i tell from this?

[Dober89]

What year is your car??? Im asuming its a 10 bolt??

Is there an ID tag attached to one of the cover bolts??

[zboom86]

is a 10 bolt the same as a dana 60?

[89IROC&RS]

no dana 60 is different, and yes, just about all camaros are 10 bolt, Z's are posi, most others are open, as for gear ratio, look at your build sheet aka spid label, and look for the three digit code GU#, and post it. well be able to tell you your gear ratio from that.

[Dober89]

Dont forget about the wonderful 9 bolt rear end.

[korndogg]

its actually a 12 bolt and ill look tonight

[89IROC&RS]

um...... 9 bolt???? eh as far as a 12 bolt, im guessing were talking aftermarket, in which case theres no way we can tell you, or its a first gen, in which case ill have to do some digging on how to decode those, they might have different codes for the gears, i assumed we were talking third or fourth gen here.

[korndogg]

well what i did yesterday was turned the tire one rotation and counted how many times the drive shaft turned.....it came out to a little over 3 and a half times.....i heard thats a way of telling...

[89IROC&RS]

yeah i suppose that could work, kinda a guestumation way, so like 3.50 or 3.73 gears or somethin.

[korndogg]

yeah..somewhere like that....now...im in the middle of puttin the 700r4 in....what gears do you think i should go with?

[89IROC&RS]

should work quite nice with what your runnin already, assuming that your guess is right. converter is more a worry for that. stall speed and all. for instance, my 700R4 is shifting weird, and flashing to stall speed in fourth gear, because im running a 2800 stall converter with 2.77 gears. im throwing in a set of 3.27 gears because they are better matched to the stall speed in the converter.

[korndogg]

ok ...the converter that im getting is a 2200-2400 non lockup....

[89IROC&RS]

eh, if youre running the 700R4, i would get the lockup, its worth a few MPG and if you wire it to lockup in second gear, its worth a few tenths in the quarter, but using that regularly will burn up the lockup clutch pretty fast. but with gears and a loose converter, the lockup feature is worth its weight in gold.

[korndogg]

ugh i dunno what to get...people tell me to get it and others tell me not to cause i dont need it.

[korndogg]

oh by the way...its a 68 if i didnt tell you
