Looking for a 63 LeMans power steering pump pulley.
Specs for the pulley would be good too.
Than you,
Pat

[PLongen]

Found pulley
thanks

[tom s]

FYI,the tempest PS is power assisted like early Mustangs and early Corvettes.Works pretty good.Tom

63-67 Corvettes used similar slave cylinders, lines etc. The pump brackets you might to make?

[PLongen]

I would like to get a picture of the brackets, there's a picture of the brackets in the manual but doesn't show the pulley side.

I don't have a picture of the front bracket without the pulley in the way but you can see its general shape. Bracket is about 1/4" thick and has a jog to it. There is also a bracket to support back of pump. You need the correct ps pulley so it will line up with water pump pulley.

You would also need a PS center link, control valve, slave cylinder and hoses. A hole has to be made in fender well for the pump hoses to pass thru. Also need a bracket to mount slave cylinder to frame. A different pitman arm for ps also.

Your best bet is to find a junk 61-63 4-cyl. Tempest with power steering. There are rebuild kits readily available for the pump, control valve and slave cylinder as Corvettes used the same rebuild kits.

thanks for the pictures that helps. All need now is a templet to make the front bracket. It shouldn't be to hard.

Still looking g for fenders and quarters for a 61 tempest if anyone has a bead on some lmk

They did make a 3.90 gear,had a set in my 63HO car I bought new in 63.I think pretty rare and takes a diff carrier as I remember.Dont know what uother gears were inbetween that required a dif carrier.Tom

I believe they also had something around a 3.55 and 3.78. Those 3 seem to all be harder to find. I’ve seen a bunch if 3.09.

Flexplate for 63 V8. My friend is in need of one and lives in Canada. The land of no 63 LeMans parts.

Stop looking, I dug deep into my stash and found one.

I am no 4 cylinder Pontiac expert, but I read your post and thought "If he can't find a Trophy 4 cam, why not use a V8 cam?" So then I Googled "can you use a Pontiac V8 camshaft in a Pontiac Tempest 4 cylinder engine?". The answer I got was ....

"Yes, you can use a standard Pontiac V8 camshaft in a 1961–1963 Pontiac Tempest 4-cylinder engine (the 194.5ci "Trophy 4"). Because Pontiac made the 4-cylinder by essentially cutting a 389 cubic-inch V8 in half, the cam dimensions match."

... but that was followed by ...

"However, there is a catch regarding engine rotation.

The 1961–1963 "Trophy 4" (Pushrod Engine)Compatibility: The camshafts for early V8s and the 4-cylinder share the same lobe spacing, base circle, and block-mounted design.

The Catch: Some early 4-cylinder Tempests used a unique "rope drive" flexible driveshaft that connected to a rear-mounted transaxle. These specific engines rotated backwards (counter-clockwise). If your 4-cylinder is a standard, front-mounted engine, a V8 cam will work. If your Tempest has the unique rear-mounted transaxle, a standard V8 cam will run your engine in reverse."

... REALLY? I thought ALL 4 cylinder Tempests used the flex driveshaft. And I've never heard that the half-a-V8 engine turned backwards.

Anyway, if the Trophy 4 does NOT rotate backwards and you can find specs for the cam you are looking for I'd bet that you could find a Pontiac V8 cam with similar specs.

My apologies if the Trophy 4 really does turn backwards.

Bill, thanks for taking the time to respond the trophy 4 is indeed a half of a 389 but the problem arises due to the rod journals being 180 degrees apart and a v 8 s are 90 degrees so half the lobes will be in wrong spot. Yes the 61-63 tempest have a transaxle in the rear with a "rope drive" drive shaft which in reality a approximately a 5/8 steel shaft.

The timing on the Trophy 4 is different than the V8. If you want to use the V8 Cam, you have to use a V8 Crankshaft. It has been done. Not by me, but it was discussed on this forum many years ago. When it comes to the Trophy 4 and the transaxles, Google is not your friend, most suppliers don't know these cars that well either. I have been around these cars for over 45 years, I have had many arguments with people who say their parts will fit when they don't.

The main parts of the Trophy 4 that are different than the V8 are the Crankshaft, Camshaft, Distributor, Valley pan, Air Cleaner, Intake and Carb.

Search this forum for Charlie66, he has a turbo on his Trophy 4, he estimates around 800HP on his engine. There are others that getting a ton of HP out of these engines.

[Bill Hanlon]

V8 cam blanks are available from a number of sources. Maybe that would be the way to go. Who cares if there are 8 uncut "lobes"?

[Bill Hanlon]

I learned something today. Thanks.

So the crank is "flat", causing one compression cycle every 1/2 turn. With cyls 1 and 4 "paired" as far as coming to TDC at the same time and 2 and 3 "paired". Makes sense.

Bill let me check I should have a stock cam around here

Hey Bill I have a 4cyl cam
