S-SS or bone stock?

FlyingW · 11-25-2012, 10:04 PM

from what i know its bone stock... Straight from olds and still has shipping straps attached...

Depending on the year & casting of this 403 motor, it might be worth some coin to someone restoring one of those Smokey & the Bandit Trans Ams that they used back in the late 70's...maybe do some homework or have it checked out at a machine shop unless you know what to check for...once you've done that, throw it on ebay and watch the bidding action.

Flying W you have a pm.

FlyingW · 11-30-2012, 10:58 PM

Yeah I totally agree with you. I am thinking that there are some people out there that would love to use this for a resto project...
What I know about it is that it came from factory, its still strapped to the pallet that it was attached to and all the numbers are matching from the carb down including the exhaust manifolds... As you know resto people are looking for that sort of thing.
The seal has never been broken since it has been in our possession... Not to mention... "OLDS is no longer a company" so we are dealing with a chunk of history...
Thanks for the article that was neat to read...

403

The 455 "big block" Olds V8 was replaced in 1977 with the 403 cu in (6.6 L) "small block" V8. It used a wide 4.351 in (110.5 mm) bore, the largest ever used in a small-block V8, with the Olds small-block standard deck and 3.385 in (86.0 mm) stroke. The bore was so wide that the cylinder walls were "siamesed" (similar to another GM 400 CID small block engine) — there was no space for coolant flow between the cylinders. This sometimes led to overheating problems. Some very early 403s were painted metallic blue like the 455, but most were painted GM Corporate Blue.
The Olds 403 was used by Buick and Pontiac in addition to Oldsmobile. The engine was only produced through 1979. Output was 185 hp (138 kW) and 320 lb·ft (430 N·m).

Applications:

1977 Buick Century Estate
1977–1979 Buick Riviera
1977–1979 Buick Electra
1977–1979 Buick Estate Wagon
1977–1979 Buick LeSabre
1977 Oldsmobile Cutlass
1977 Oldsmobile Vista Cruiser
1977 Pontiac Bonneville
1977–1978 Oldsmobile Delta 88
1977–1978 Oldsmobile Toronado
1977–1979 Oldsmobile 98
1977–1979 Oldsmobile Custom Cruiser
1977–1979 Pontiac Trans Am
1977 Pontiac Grand Prix available with California Emissions Only
1977–1978 GMC Motorhome

FlyingW, perhaps you could do somemore research on those '77 to '79 Firebirds equipped with the 403 motor...or maybe start looking for one of those cars yourself, but find a real clean southern body not needing to much body work and restore it...just a thought.

Solid web 403s are rare. Most are window webs. Only about 2500 solid webs made. I just always thought all the solid webs went into GMC motorhomes. 77 and later Olds V8s were thinned out for weight savings. Some say this engine has cooling problems because of the windowed webs. If Olds sent this engine for racing it could be a solid web motor. I once got a common 403 out of a 77-79 Buick Riviera and ran it in a 69 Cutlass Cruiser wagon and it did ok. Had over 100k miles on it. Mine was bone stock and ran pretty close to a 350 Rocket. They started putting 403s in Trans Ams in California and high altitude cars. In 79 the highest production for Trans Ams at 109,000, around 92,000 or 94,000 had 403s. Those 403 Trans Ams were handicapped with airplane gears as opposed to the 400 Pontiac powered cars with 3.08 or 3.23.
