Look at this:-)

Are these tuned &quot;ringers&quot;, or were these regular production engines? </div></div>

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]

Just sharing the OLDS love........one of the most powerful Muscle cars with Both small and Big Block as well as arguably the best handling non pony car........most don't know very much about them.

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.
