Transmission options

[1000j]

I'm in the process of building my 66 Coroner Deluxe, car is stripped down completely, replacing floors ,trunk pan etc no major modifications, adding frame connectors torque boxes, keeping a stock look, drive train missing when I purchased it, 66 hemi being rebuilt with the 671 blower it was raced with until 1972, hat is converted to fuel injection from the old mechanical injection, Moser or strange Dana 60 is the plan but I can't decide on transmission, been looking into silver sport 5 speed or auto, expect to dyno in the 700 hp range,not racing it just a driver...looking for opinions

I am an automatic fan and went with a TF and GV unit on my street car with more power than your plan.

I think you will be way happier with a built automatic and the right converter. Going manual is not cheap and there is a lot more going on. With a motor making good quick power you will be rowing gears like a mad man. For overall street use the automatic will be a whole lot easier to drive.

I did consider going that route originally, probably the better way to go, thx

Yeah that makes sense,the car was an automatic originally and my other two b bodies are 4spds already

The '69 Hemi Road Runner that I am trying to get together had a 4-speed, I even got a scattershield for it. Then decided the hell with it, I'm getting an automatic. So it's now got a 727 reverse valve body Coan trans in it. I'm not looking back. Be happy!

Ha! I have a 67 Deluxe wagon. Money wise, work wise, the best bang for your buck will be a 727 with a Gear Vendors unit. I have that planned for the wagon down the road. When I talked to the rep from GV last year at the SEMA show, he said if I stay with the 18" extension housing length[ normal passenger car], the only floor mods would be just some minor thumping on the floor near the seat belt anchors for the front seat. Going manual is more work due to floor mods, pedal units, clutch actuation[ hyd or manual], trans type, clutch package good enough to handle to power output[ going to require more left leg strength depending on type chosen]. Manual is harder on the diff, but if you go with a 60, you should be fine. For sure, get structure reinforcements in regardless of trans chosen. I made SFC's for the wagon. That was the first underside improvement I did before the other work.

When I got my camper van, I had some knowledge about the 318 being quite reliable. I was not aware the 727 and Dana 60 with so bullet proof. I had been thinking about a floating axle rear end. Doug helped me with installing a shift kit in the 727, and I am happy with that. I am running a fraction of the 700 hp proposed.
