One more thing-can the stock rear be beefed up enough to handle it.

They are notorious for being weak, I wouldn't even dream of it.

Yes,the 265 was only available in a two barrel. Same # 3731548 block but smaller bore.
No they should not allow 4 speeds(manual) in stock. Blasphemy I say! Besides you have to do some real hanky panky to make the shifter clear the original bench seat. Whats next bucket seats in stock.

The stock 10 bolt rearend would not be a good choice. They are very weak and I doubt if pro gears are even available anymore. They only came as low as 6.17 and had 6 teeth on the pinion. After a couple of passes they end up with zero. I believe the yoke is a 1310 too.

My choice would be a Mark William's 12 bolt with as low as gear ratio possible and big wheel studs.
Transmission would be a Jerico DR-4 (although they no longer sell them new) with a 3.08 first,2.10 second & 1:1 third. G-Force would also work. You can underdrive third on them.

Allan - Make no mistake - I'm a purist at heart ...........................that being said you have to remember that none of the cars I race came with Metric 200's so a 4 speed in a '57 Bel Air is not a stretch for me .Blasphemy - not hardly as they ran them for awhile in the old days before they were outlawed .As far as the shifter thing is concerned Hurst made a really neat deal for these cars so the seat wouldn't have to be altered .

Yes I suppose you are right on that one. I guess I need to not be so rigid in my ways as I am quite pleased that I now that have a Jerico and not that old pro-shifted T-16 or the toploader. Hopefully I can put an end to all those granny shifting jokes and maybe even pick up a bit.

One of "my" demands when I got the Jerico is that they move the Long shifter far enough ahead to clear my stock seat. Scott did just that for me, not something they have ever been asked for before. It now sits 17" from the front of the transmission.
I remember that old Hurst horseshoe handle where the shifter was well under the seat.

i tried to get a 6 speed for the overdrive cars but they would not even discuss it (it has SS issues) but in reality you can let out the clutch and move forward in 6 different ratios enclosed inside the factory case.

and the turboglide was a 3 speed (has two planetaries) so i just got it recognized. for 57-61 some cars not available 6cyl and high HP 348-409.

captain...
57 would be cool ! intake & carb sucks though we do not get 459 and smaller carb

I would think the rear could live " beefed" for an automatic...Of course the 12-bolt would be stronger...and has a better list of parts available. But if you're "gung-ho" on "flogging" that 10-bolt...you'd have to work around some disadvantages...One is I don't think anybody made "Pro" Gears for this application EVER...so I would suggest "prepping" the available gear sets as best you can...de-burring, heat-treating, or whatever "current" metal process is suggested for stress-relieving today. Another problem with the "old" gears is ratio selection is a bit weak as they jump from 5.57 to 6.17 while the 12-bolt has 5.57/5.86/6.00, and 6.14 ratios...a better selection to "fine-tune" your combo with. Yes, the pinion is small on the 10-bolt 6.17 ring & pinion as mentioned before...a definate liability! BUT your combo might not require such a "stout" ratio depending on what you will run for tire size, trans ratio, etc....Another problem with the early rear end is I don't think anybody made a SPOOL for it although it could be "custom-made"...check out "Aubrey's " site the guy in Canada with the 409 car. I think he's running the 10-bolt in that car still....although a LOT of work to make it live. The GM "Arma-Steel" posi unit is pretty strong BUT needs help with NEW heat-treated FINE-SPLINED spider gears (for the custom axles), and other mods. Unless you have one of these NOW, they could be a bit pricey at swap meets today...I would also consider steel differential carrier "caps" (or reinforcing straps for the stock caps), larger grade-8 bolts, etc. All of these mods were pretty much "standard-issue" for racers running this rear-end back in the day...although today's horsepower levels, better tires, and better track prep should be factored in the decision...I would try and contact Aubrey...or maybe Tom's Differentials for more input on your situation....Good Luck!

Jack is right about the 4 speed. My dad raced a '57 150 in the late 60's with a 265 in Q/S. It started out with a 3 speed stick and then a 4 speed until they were outlawed in stock. Instead of going back to the 3 speed he changed over to F/MP. All before my time, but he still tells stories of those days gone by.
