I'm thinking of running an interceptor intake on my 64 292. Any one have any info I should know before I start work on it. I'm going more for look than performance.

I know marine carbs are set up a little different than street to take the vibrations and poundings of the waves, the floats and venting are different so they don't bounce around letting excess gas in when the boat rocks and then splashing it out the venting creating a fire hazard. I don't know the specifics and I know it is not good to use a streat carb on a boat but the other way around shouldn't be a big problem. I think jetting is very fat on marine carbs so you may have to do some jetting work.

They must use some type of marine carb on those off road race buggies to take all the jumps, I'm not sure what they use.

Side draft or down draft manifold?

Its the dual carb side draft

I'm new to Y blocks and knew nothing about them until last year, but now own a beautiful 312 in a boat with a down draft set up and a 256 with a side draft set up that I will be parting out in the spring.  My understanding is the side drafts run well if set up correctly.  Apparently they have a tendancy to puke gas out if not set up right creating a fire hazzard in a boat.  At some point Interceptor started using valley pans that were recessed to allow the gas to collect in the pan rather than running into the bilge.  They used them for the low profile they had, allowing the boats to have a lower motor box.  Many engines have been converted to downdrafts because of the difficulty in getting them to run right, however, a person I know has them in his boat and says if you're somewhat manchanically inclined and understand carbs they are not hard to set up and keep running good.  They are cool looking.

They used the same basic carbs on the scrubvette blue flame six in 53/54. So I think they would work. Not a lot of CFM but definitely different. I believe the deep valley pan was to allow for the low set manifold and linkage rather than a gas collector. You need that pan plus the connectors for the water passages that fit on the front of the manifold. Chuck in NH

Howdy,





I am going to try a "marine" carb too. It's a Holley 4160 that I removed from my previous OMC 460 King Cobra stern drive after I "parted it out"





I will be rejetting it...... it also has vacuum secondaries so I don't really expect many problems with it.





the Interceptor setup could be a problem in a non-marine application only because of possible vapor lock due to the carbs being much closer to the heat source (in the "valley") and the fact that the engine will be running "hotter" than a marine application. Most marine engines use a 140* t-stat and use an unlimited "heat sink" (the lake)



Your Y should probably use a 180* 'stat which will make the under hood and "up close and personal " temps much higher.



I like that manifold and carbs too. I think they look at least as cool as the 3x2 set up.









Cheers,





Rick

I was under the impression marine equipment was always better than street machines.

Thanks for all the info guys. do any of you know the cfm of the sidedraft compared to the factory 2bbl the 292 comes with?
