So as best as can be determined without documentation I have a lower HP BB RS/SS that came with a 3.07 12 bolt axle and suspected auto.I dont know how the 396/375 came to be in it,unless the tach was placed in there due to a production shortage or engine was dealer install? I never did have a protectoplate and never found any build sheet.I have a Norwood 04C. I also suspect it had a dealer installed Posi as the original deck lid had a posi decal warning about jacking car.Currently it is a 4.10.
I will have it as a L88 427,Muncie M21 and probably 3.73 gears.I am considering a chambered exh system for it.Talk about a sleeper.I may just put a 396/375 decal on the air cleaner.Since I have no plan to sell I wont care about documents and would never represent it other than what it is if I did sell.
Besides an L88 second design engine is worth quite a bit just by itself.
Now,did I ever mention the time I was offered a SBC Crossram and carb set up for $175 and TURNED IT DOWN?? Also could have Purchased a BBC 3X2 set up complete for $400. Ah.. if only I could have envisioned what that stuff is worth today.
