455, finally, and I'm still cheap.

[STL84Calais]

Ok, so I picked up my 455 finally, I lucked out. It's a 1970 455 from a toronado so its 10.25:1 compression with approx 375hp from the factory. It is a running engine! So I'm just going to go through it and do new seals, bearings, etc. plus some performance improvements above factory. If you have any of this lying around, and are willing to let it go, let me know!

-Gbody 455 headers OR a good set of manifolds that'll work for a Gbody
-A Mondello JM18-20 cam
-Edelbrock Performer intake for a 455 Olds

That was a front wheel drive car believe it or not.
1970 Olds Toronado GT, 400 HP V8 front wheel drive, 455 cubic inch Rocket V8. The GT is a rare 1970 Toronado option (W34). The W34 option provides an additional 25 horsepower from the 455 by using larger intake valves, dual exhaust, a performance cam and a higher stall speed torque converter similar to a W30 442 option in a rear drive Olds. The compression ratio is 10.25:1. this is what i've found about the motor, you should find out if yours is a GT motor.

Nice find!!

you should find out if yours is a GT motor.

The only way is to remove the heads and measure the valves.

There's more than ONLY one way,,,, he could check the VIN number of the donor car if available or he could look at the transmission code It is on the left side of the transmission and riveted to the case. It should have the letters OM instead of a regular Toronado transmission letters OJ. If you find an OM, wipe off the grease and look for the VIN stamped on the transmission case near the code letters. If this VIN matches the car VIN you are half way finished. Next remove the power steering pump bracket that attaches to the left side of the engine block. Under the bracket is another VIN on the engine block which must match the transmission and frame VIN. If all match, congratulations, it is a W-34 regardless of the rest of the appearance. Remember, it is the combination of motor and transmission that makes these cars unique. Another way to check the motor would be to pull the cam and check the identification on the end.
You see,,, there is always more than one way to find things out.

The donor car isn't a GT, but the guy did have one believe it or not, I think like only 1200 made for 1970. He is selling another 455 in the near future from another toronado. I'll have pics soon, tear down and build up.

Sweet! Now get it in there!

Ok, I know y'all are going to say WTF to this question, but will the 455 bolt to my Metric 200 transmission that is currently behind my 307? I know it won't handle the power of the 455 during a hard run, but I figure it'll hold up to VERY LIGHT driving untill I get the TH400 built (taking to car shows, etc.)

Yes it will. Just don't be surprised if it does go with even light driving. Just try to get the 400 in there soon.
