Thread: New Street Rodder from IN

Tweet

Welcome to the forum. Ya, Oldsmobile, you're talking my language now!! Olds are my favorites by far, and that 70 455 is a great one to build. Good compression, not much smog stuff yet, and as strong as a bull.

We built a 455 for my Son's '29, and didn't really have to do much to it........forged flattop pistons, pretty radical Crane cam, Ga heads that have SS bigger valves, good ignition, and a tripower setup from a '66 Olds 442 (don't look, they only made 1200 of them ) Haven't had it fired yet, but it should move the car pretty well.

Mondello's is a good Olds source, but I would think that a good rebuild, some cleanup on the heads, an aluminum intake with a good Holley or Edelbrock carb of about 800-850 cfm, some headers, decent street cam and ignition, and you would be very happy with the results. My other Son had one in his '65 Jetstar convertible, and he surprised a few cars with it.

Here is the one we built for the '29.

Good luck,

Don
