1970 w-350 intake for sale

1971cutlassS · 11-29-2007, 08:46 AM

I have an intake off of a 1970 442 w-31. its aluminum and has w-350 and oldsmobile cast into it. How much is something like this worth? I also have the carb and running motor. should i just sell it all together or keep the long block for my 71 S project?

thanks in advance

If it were me I'd keep it together and try to sell it as a unit if you can prove it's the correct W31 engine. If you don't need the intake you could sell it and purchase a Performer RPM that will breath better. Price? That's kind of difficult, I'd look to ebay and see what they've been selling for. Even there it's possible that one sold during a bidding war and then the high bidder declined to follow through with the purchase. I would guess a low price would be around $400 and the high could be up around $700. I know that's a big range, but the prices I've seen over the last year were scattered in that range. Also I believe the W31 heads had bigger valves than other 350's. If that's true there would be demand for the heads too. John
