I've spent the last several days compiling whatever I've been able to find on the early Oldsmobile V8s. Much of this information is a compilation of what I've found on the internet. Most of the contributors are DON_WOW, BlownOlds, Yorgatron, Blackrat40, C9, and Dennis Choinski. I'm sorry if I didn't include you, I forgot to. Just wanted to give credit where credit is due. I sure wish I could have talked with some of these old timers. Oldsmobile isn't around anymore and these old fellows won't be here forever. As the younger generation it is our responsibility to get this information so it may be passed on. If you have anything to add, don't hesitate to send me a message. I always want to learn more. Actually, I would like to have someone post factory bearing clearances for the 303, 324, 371, & 394 if they have the information. What kind of clearances do you guys run if you're going to be drag racing/circle track/cruising these motors? Is there any sort of clearances you choose for a specific horsepower range, etc? Also, I would like any proven stroker recipes that you guys have. Please include whatever special machine work is needed for the recipe to work. I know a 455 Oldsmobile crank won't cram into a 324 without a lot of work. Hope this consolidated guide will help you fellow Oldsmobile enthusiasts out there. -Mitch Next post will be the guide!
