You can get an expensive generic Holley rebuild kit, or you can get a specific kit from Drew at Air Fuel Spark.

Thanks.

This is great information. I was told that the carb was used on 390 engines in ford automobiles. If it is for a marine engine then I will not use it and toss it out.

I'm so sorry...I just gave you the total schpiel for a 6361. I apologize. I also have a 3796. I will delete prior post.

Incidentally, the same carb kit works for the 3796. 3-1184

Yes, the 3796 is a GT390 carb. Like the 6361, it has some strange behaviors. I had to install an adjustable pod to get the secondaries to open slow enough so as not to cause a lean hesitation. I put adjustable primary and secondary metering blocks so I could tune the power valve and idle feed restrictors.

That carb doesn't have a PCV port, so beware. The 390 used a tube that connected to opposite runners on the intake as opposed to a port in the main plenum. I tried one of those expensive 428 carb spacers (that has PCV port) and it won't seal on a typical intake or carb....there's a portion of the pcv port that's doesn't get covered and would result in severe vacuum leak.

Here's some factory tune info on the 3796. The PVCR and IAB sizes are for original metering blocks.

Basstrix,

Where did you get this info? I've been looking for this type of breakdown for some time, and the only thing I find is very expensive Holley books on eBay.

Most of it I measured myself with gauge pins but some of it is out there, as well. If you come across a comprehensive list, please let me know...and I'll do the same if I should find one.
