| | THANKS!
For helping keep this great
old truck web site
on the Internet for over 30 years! and not clogged down with Ads! Again, thanks! | | | | Joined: Dec 2006 Posts: 25 Wrench Fetcher | | Wrench Fetcher Joined: Dec 2006 Posts: 25 | I have a 1951 3100 with 216cid, It runs fine and I have had all the body work done and want to make it a driver. I have read all about how to get more speed out of the 235 and can find add-on intakes to put 4 barrelcarb on. But can't find any info on 4 barrel intake for a 216, or are the both the same? any help or ideas would be much appreciated | | | | | Joined: Nov 2008 Posts: 465 'Bolter | | 'Bolter Joined: Nov 2008 Posts: 465 | Contact Stoveboltengineco.com
The 216 according to all cannot handle anything more than the Carb it came with .
The 235 has so many advantages for power and upgrades .
Just my observation

The 235 intake can work on your 216, has slightly larger intake runners, I ran one on my 261 for many years. But the 235 intake will not mate up to your stock 216 exhaust, so you can use fentons or just use a 235 exhaust. Also you may want to check out www.inliners.org | | | | | Joined: Dec 2006 Posts: 25 Wrench Fetcher | | Wrench Fetcher Joined: Dec 2006 Posts: 25 | Jim. Thanks for your help. but let me aske you. what about a Offenhouser or Fenton setup for a 235, will that work on a 216 ?? | | | | | Joined: Sep 2006 Posts: 2,393 Shop Shark | | Shop Shark Joined: Sep 2006 Posts: 2,393 | In it's time, Offenhauser made a 2 carb intake for the 216 as well as the 235, but they are not the same as there is a difference in intake port diameter.The 216 has smaller ports.I think the Offy part numbers were: 216=1032 235=1034 I'm not sure how today's repros are numbered.

Use the search feature on +3.55 +rear and you will find a lot to read about a common rear end conversion.

You need to get their catalog, lots of GOOOOOD info. 216 intake is a bit of a different animal than one for a 235 but both will bolt up as I said. I'd just start collecting catalogs from ALL the vendors so you can see what's out there. Patrick's, Langdon's Stovebolt, Chevs of the 40s etc etc. And read this entire website/tech tips and the same over at Inliners.org. | | |
