Oldsmobile 350 W-31-----325@5400----360@3600------350@5800

Look at this:-)

Are these tuned "ringers", or were these regular production engines?

The Standard 4 bbl 350 Grandma Olds put out 310.......so add higher compression select fit rotating assembly, huge duration cam/kit, special carb, dist and aluminum intake, plus special heads with better ports and huge valves and Ram Air /OAI........yeah I think thats good for 50hp at the flywheel [img]<<GRAEMLIN_URL>>/wink.gif[/img]

Thanks Stefano…Great information! Oldsmobile’s GM John Beltz had major plans for the W-Machines. Sadly the new U.S. governmental emission regulations put an end to the release of the incredible W-43 set for 1970-1971 Oldsmobile 442 W-30s.

As far as the ZL-1 – I remember reading that the L-88 produced a bit more HP than the ZL-1 due to the heat/compression it produced therefore creating more HP. Although the HP gains were offset by the weight savings of the aluminum block and heads of the ZL-1.

That's an awesome engine. Thanks for the link. It's a shame we didn't get a few more good years in before the emission and safety regulations kicked in as there was some great stuff in the works.

Thank you Jon - I really appreciate your posting the link and photo. Nothing that I post on the site is working correctly lately – not sure what I am doing wrong. Yes, it would have been so cool to see the different High-Performance hardware all the manufacturers had in their planning books. I hope you have a very Merry Christmas!

Happy to help, John. Merry Christmas to you also!

Still available and very difficult to find a W-30 with proof (factory docs) that is was born a 4 speed and thus received the special 328 degree Cam as well as a bunch more HP. A large percentage of the existing cars have no such proof.

Great car and posts Stefano. I couldn't agree more. The real joke in Oldsmobile isn't the 350/310, it's the early 330s. How about a '67 Cutlass that Granny or the Librarian goes into the showroom to buy. She wants a four door with white walls. Standard engine is a 330/320 horse with single exhaust and an open rear that would annihilate that poor right rear tire. 330/320 steel crank, would rev to 6500 before floating the valves, and probably so 90 in first gear of the Jetaway. One of Oldsmobiles secrets was that engine with a 4-speed and 3.23 in a light 2Dr post. Would embarrass a whole lot of takers.
