Remember a Camaro/Firebird LT1 shoot out at Englishtown mid 90s.
Had a bolt on class, cam only, head cam, stroker heads up classes.
All still using the 7.5 rear and making it last.
Got old magazine issues that showed how they made them work.

Today you can get a complete Moser 12 bolt.
With heavy duty brand new everything for about $2000.
It is a good long term investment for a dedicated race car.

Because the Dana 44 came in 83-86 Camaro's I could use one in the 85 camaro i will be starting? Correct?

Will Lamprecht
1965 I/sA Impala
85 Camaro W/SA TBI L4 possible

Yes, but finding one will be a chore. AFAIK none were installed assembly line. They were sold OTC and will be very rare.

I think the Aussie built , Dana 44 were only found in Pontiac Formula's and Trans Am's . Camaro's used the 7.5 which was later upgraded to a 7 5/8 . At the junkyard, you would be wasting your time looking under a Camaro. There was one on Detroit Craigslist just last week, so you should be able to find one .

The 9 bolt came in 5.7 Formula Firebirds for sure ,got one on the driveway. By time I got my 305 running in my 83' Camaro it had a 2.75 low gear trans, 5.13 gears, and a 5200 stall converter. If you think you can throw that, and slicks, at a 7.5 and not worry about it about it I would say you are fooling yourself. And that engine dyno'd at 345 hp, there's a good chance you will make more. Go with the Chevelle 12-bolt if you don't have the money for a complete Moser, you won't find the gear you want with a 9 bolt. I might still go to the Moser in my car. Build the suspension in the car solid, you might want to do something different with it later as life situations and locations change. I got a 385 Vortec head SBC in mine now and bracket race it.

Now the 9 bolt or 7.5 might hold up to a L4, but I don't know what's needed to get one moving. The L4 Camaros were real dogs, maybe got good mileage though.

I run C/ps and use 7 5/8 rear end. Made it 75 passes at 1.60 60 ft times on stock posi with 4.56 gears, jegs axles, rear support cover, a quality gear. Broke Posi Gears. Then put in a Detroit tru trac and have put 45 more passes on it with 60s in the 1.55. Run 12.40s in qtr. 7 5/8 has less drag then a 12 bolt or equal. Lots of guys are going low 11s with an auto.

I'm not sure how to tell which rear is in this car, 7.5 or 7 5/8. I'm thinking about bracing the housing, putting a gear in it, c-clip eliminators, and a girdle cover and running it. If money was no object I'd go with the strange 12 bolt housing, which it might come to later.

I ran my Camaro for several years with a completely stock 7.5 running low 14's. When I got to mid 13's I upgraded to a auburn posi and Richmond gears and then broke the rear end in no time. I would just get a 12 bolt.
