1957 150

[Tom Goldman]

66 Impalla rear will fit the 150 nicely,its within 3/8" of stock width.
Just weld on the spring pads.
I've got a '57 150 in the shop right now with this rear, altho it's got a LS 3 Vette engine in front of it!
Just keep in mind 12 bolt gear ratio availability for those little motors.
10 bolt rears have a better availability of very low ratios, and will certainly hold up behind a 265 or 283.

Here's a new twist - since they allow a Metric 200 via the "Jack McCarthy" rule should they allow a 4 speed in this car because it came with a 3 speed with overdrive ?

Jack; that's why I love this site-somebody always thinkin'- I'll talk to Cal method more about this idea at next weeks divisional. thanks everyone for all their input!

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
