434 Small Block Oldsmobile stroker Diesel to gas conversion Monster Oldsmobile part 2
This is actually the first video that I took of this engine this one was
before I put my headers on and I took the pan off after this video just to
make sure everything looked good. I re-ran to make sure nothing leaked.
Well I took a 350 Oldsmobile Diesel and converted it to gas. It has a 425
big block Olds crank, BBC connecting rods, edelbrock heads, 850 cfm carb,
11:1 compression with about 550hp. Who would have thought it was originally
a Diesel engine
OLDSMOBILE 455 W-43 EXPERIMENTAL HEMI AND OTHER EXOTIC ENGINES - THE JOHN BELTZ YEARS PHOTO TRIBUTE
John Beltz was Oldsmobile's chief engineer in 1964 and one of the prime
movers of the Toronado and 442 project. Beltz was promoted to Oldsmobile
general manager at age 43 in 1969 when Harold N. Metzel retired. Beltz
passed away in May of 1972 from cancer at the age of 46.
John Beltz is leaning on a dual fan 455 Olds and posing with other
experimental Olds engines that never saw production.
Here are descriptions of these engines:
1. The 0W-43 all aluminum 455 with 4 valve per cylinders, four overhead cam
Weber engine. With a redline of just under 8,500rpm it was originally
conceived for CAN AM racing. At 3,000rpm it put out 300hp and at 6,000rpm
registered over 600hp. The top output recorded for this engine in the
Lansing Dyno facility
was 700 real hp at 6,800rpm. Tests were run with both carbueration and fuel
injection. The block was cast from Reynolds 356 alloy and fitted with
pressed-in dry steel cylinder liners for the Forged-True 12.20to 1 pistons.
Billet steel connecting rods by Carillo was used along with a forged steel
crank. The engine weighed in at 50 pounds lighter than the production 455
motor! It was developed at the same time as the ZL-1 Chevy 427 motor.
2. The W-43 4 valve per cylinder 455 developed by JOHN BELTZ , LLOYD GILL ,
JOE JONES AND FRANK BALL. Rated at 500-550hp with a single Rochester
Quadrajet on an aluminum manifold. Constructed with both cast iron heads
and block and with aluminum-alloy block and heads 75 pounds lighter than
the conventional 455 production engine. Engine featured four valves per
cylinder with narrowed angles for a super efficient combustion chamber
design, central spark plugs and could easily be adapted for chain for gear
driven overhead camshafts. 455 engine had 4.625inch cylinder centers, a
4.125 bore and 4.250 stroke. Making use of the 3inch main bearings and 2.50
inch rod journals, the engine was fitted with a specially prepared cast
crank fitted with SAE-1140 forged steel rods, forged 10.20-to-1 pistons
which rode on Morraine 400 bearings. Four bolt main block boasted 2
additional 5/8inch drain holes. Four valve heads featured 1.750inch intake
valves (SAE-8640 steel) with 22 degree stems and 1.375 Exhaust (214-N stainless steel) with 15 degree
stems, special Stellite seats, bronze alloy guides, o ring plug tubes, 14mm
spark plugs, 3/8 inch pushrods and aluminum rocker arms. (Of all the
experimental Olds engines, this one came the closest to production and
there are photos of this engine in street gear. MAY 71 HOT ROD MAGAZINE
features some of these engines and the sadness of the Olds engineers of
that time of how they would never be released.)
3. 455 dual turbocharged CAN AM ROCKET
CHALLENGE. 659hp @ 6250rpm. 554lbs torque @ 6,250 rpm. Alloy block with 4
bolt mains. Forged steel crankshaft. Forged True pistons with 8.5 to 1
compression. 3inch main journals. 2.499inch rod journals. Carillo billet
steel rods. alloy heads. 2inch intake valves. 1.625inch Exhaust valves. Crower roller camshaft with
555inch lift and 320 degrees duration. Dual TRW-375-E-10 turbochargers with Boost Wastegate 10and 1/2psi. Lucas fuel
injection. Olds alloy intake.
Competed with big block Chevy Mclarens and Porsche Panzers in CAN AM racing
This video is merely a couple of old magazine pages strung together with
the exception of that blue 455 hemi which was found on the internet. Thats
BRUCE MCLAREN in that green can am race car which is Olds powered. AT THE
BEGINNING OF THE VIDEO JOHN BELTZ IS POSING WITH SOME ENGINES FEATURED IN
THE JULY 1969 ISSUE OF HOT ROD MAGAZINE AND THE BLUE OLDSMOBILE 455 HEMI
WAS FEATURED IN THE MAY 1971 ISSUE OF HOT ROD MAGAZINE. The incidental
music I overlayed onto this video was muted by youtube.
