So what can you guys tell me about 68 Olds 400 motors. Are they worth building to get power...Also is a 68 Olds tri-power setup worth some money. The guy I might get the motor off of said the are worth a ton and they are rare...
No such thing as a 68 tri power 66 was the last year. If i`m correct i think the 67 and earlier was the better motor they had a different bore and stroke combo. I don`t think the motor would be worth much only maybee if you needed it for a 68 442?
As an owner of a 68 442 I can tell you they do run well and are reliable the 3 duces you speak of is either off a 66 model or an even earlier J2 from 57. But parts and machine work is more expensive on an Olds 400 than the Chevy or other brands.
400's are good engines the tri power intake will fit the 400 ..mondello is your friend when it comes to the olds engine the oiling system will need work if you plan on turning it at high rpm's for a long period of time for the most part it is a good piece what is the letter on the heads B or E
Always have had the best luck with Oldsmobile drivetrains from the 50's up through the early 70's. Bought a 55 Olds once with a broken transplanted 394. Didn't know how bad till I tore it down and found a whole valve blown down through the top of a piston and major bent pushrods and metal floating around inside. Rough for sure, but the engine still ran and idled. Replaced it with another 394 from a 61 Dymamic. No problems............. Anything pre 74 has served me well....
Yes, the 68 Olds 400 is a long stroke small bore motor. it has lots of bottom end torque but runs out of breath early... The 66 tripower is a great piece, use it! a good hot street 400 built with the 66 - 67 motor is a higher revver than the 68... I just did a 67 engine rebuild, see it here -
the 65-67 400 is the one to have. Best bet would be sell the 68 400 to someone that needs it for a 68 442. Keep the intake, find a 425 or 455.
