Sun Super Tach II came out around 1976 or so. </div></div>

Any thoughts or opinions as to what would be accurate here? </div></div>
Sun Super Tach II was added in the mid to late 70's by subsequent owner. SST from early 70's would be more accurate. What tach does the paperwork say?

I have been fortunate to personally own 5 different BM cars over the years (including this particular car at one time) plus have seen paperwork for some others and I don't recall any paperwork calling out any particular parts to that level of detail.

For instance the invoice might say &quot;Phase III Ignition&quot; or &quot;headers&quot; which would not call out any particular components, part numbers, or brand names. In addition, Motion typically took off the shelf speed parts and rebranded them such as Mallory ignition components, cure ride shocks, Lakewood traction bars, and others calling them by another name and in some cases putting a new decal on them, so unless the car is an untouched original with vintage photos, the best you can do is use correct speed parts from the era that would have been typical of a BM build.

I am curious if the car has a 10 bolt rear or a 12 bolt and what gear ratio does it have?

I believe you can only get a 10 bolt in 1971 Camaros

looking at the 1971 Camaro specs the SS396 highest gear was 3:42 but the Z/28 still had 3:73 and 4:10 listed all were 10 bolts

Joe, this car has a 10 bolt rear end. I don't know what the ratio is, but I'll check when I pull the diff cover to change the gear oil. It's possible that Joel's crew may have changed the gears when they did the conversion.
