hi, ramblin64, would there be by any chance a build thread on those two manifolds? Making these is beyond my personal capabilities, but....care to make another pair:) thanks. gz

"To keep it simple, I made two small intakes to bolt to the 4.0 head"

There is a build thread of sorts. Search for "4.0 crank in 232 block?". Not a whole lot of documentation. With a pair of young kid's car time is short, so I didn't take a lot of time to stop and snap picture's. When I started looking at those carbs, I had a fairly long conversation with Tom Langdon of Langdons Stovebolts.com, He seemed to think that the log manifold from the early 4.0l mpfi engines would make a great platform on which to build a dual carb manifold. While I would love to build more of these manifolds, I fear the cost would make the Clifford manifolds look like a bargain. If I ever need to update these, I will keep you in mind. Jon

Here's a link with a good pic of the manifold. LOTS of custom work!
http://theamcforum.com/forum/40-crank-in-232-block_topic55329_page4.html You could get a pair of 4.0L early log intakes and cut/weld them into two three cylinder intakes, or the late 2V carb aluminum intakes. Would still be a lot of work. Not as much as making your own from scratch though. Cut and fit, then take to a welding shop with an old head so they can bolt it up and get everything aligned properly before welding. A 500 cfm 4V is typically considered the max for a healthy 258 (better cam/intake/exhaust), with 400 cfm being better for a stock/near stock engine. 4V and 2V cfm are measured differently. Multiply 4V rating by 1.414 to get ~2V, so 500 cfm comes up to a 707 cfm 2V. So the ~800 cfm won't be bad, especially since they are two stage carbs and you're running under half that (smaller primaries) most of the time. The smaller ones might be better though. To convert 2V to 4V equivalent divide 2V rating by 1.414. Edited by farna - May/03/2017 at 7:15am |
