This is for Peter Jardine, since you are working on that big dog 430 hotted up boat motor, thought you would enjoy seeing some of the tips and technology put into this one. I tried to send this as a PM but the PM is turned off for Peter, so hey, hope you see this.

This is a true torque motor. It makes 590 ft lb from 3300 to 4400 rpm

Oh yeah. Thanks Paul. I have been playing with the idea of getting a cam reground..... I do want to blueprint the intake manifold and make that match as good as possible.... and exhaust too. Generally these engines didn't breathe too badly anyway, but frankly I can't really figure out what the cam should be. I thought that slightly more lift, and maybe just a tweak of duration would be a good compromise... any suggestions?

I am using a set of early tall port heads, since they match the original marauder intake.

I have talked to the folks at Oregon Cam Grinders, but not in detail. Any suggestions in that regard? Who has blanks... which would be really great. I should contact the same grinder as this thread suggests.

Re: 430 Lincoln carb spec

Hi Peter,

Got a question for you on the 430 version of the big MEL.
What carb did Chris-Craft use for their 430 Lincoln application (in runabouts)??

I would think it was the same Carter 625-cfm AFB they used for the 427 in 1966, but need to know specifically. Anyone out there know for sure ??

regards (thanks),

Paul

Re: 430 Lincoln CARB questions

Post by Paul P » Wed Mar 05, 2014 3:28 pm

From doing a little snooping around, it appears the Carter 3041S, 3041SA, 3204S, and 3314S are probbaly all essentially the same carb. There are numerous sources that list the rebuild kits for all of these numbers.

Anyone have any specific info on the Lincoln 430 standard issue Carter AFB carb? I am just wondering what (if anything other than the stocking number) may have changed with the 3 or 4 different carbs I find listed for this same engine.

Regards,

Paul

I found an old eBay listing that was for a 3314s and claimed to be the carb for the 430.

Carter AFB's had at least five different floats, and used a stepped metering rod, which could have two steps, three steps, and I think even four steps...... I suspect that is where the numbers are different, but I can't find a number chart that helps sort that out. The boats used Carters, the cars used Holley 1850 carbs in quite a lot of applications. Other than the AFB similiarities, I don't know where the archival info would be. Bottom line is that the numbers refer to a specific fuel requirement curve, and in the case of the marine engines, the load applications would be obviously different than the automotive. Carters were simple, but you couldn't just swap out metering rods without knowing how it affected the fuel delivery curve. One last thing I forgot: the idle jets are pressed in I believe, so they could be different too. I am really not an expert on carbs.

The Carter AVS and AFB are very similar and often seen as the same carb. I had a very in depth, almost too in depth, conversation with the guy from the carb shop in Iowa where he went into the intricate details and differences in the AVS and AFB's over the years. The 3 step rods were found on the AVS, but only those with domed piston cover plates, the flat ones have the two step rods. The AFB uses a counterweight to open the secondaries where the AVS is opened with air only. The marine versions have different venting than the automotive where the vents are contained under the spark arrestor vs on the outside of the carb. The numbers were different based on the particular applications. The numbers can indicate several things including GM, Chrysler, or Marine, as well as the CFM, choke style, etc. Here is a listing of some of the Federal Mogul part numbers which you may be able to cross reference to earlier Carter model numbers. Hopefully this will shed a little light on the situation.

The AVS isn't applicable on the 430 engine, since it came out after the engine was discontinued. The AVS was a total flop, even though Carter pursued it for a while. It was a minor carb compared to the AFB.

two step, three step, and four step (a few) were found on AFB's as well.

Be careful saying the AVS was a flop, especially around the Mopar crowds.
