Chris Ramey, 441???

441 is nice! The electric pump is a good idea, but also make sure your mechanical pump is a good one... Also, don't use "too much" of an electric secondary pump...for obvious reasons. Yes- THAT mountain in Tennessee, foes up and down in "steps".

Just pulled the head, burnt intake valve, prob from unleaded fuel.

Chris,

I am planning to install an electric pump at the tank. Probably will help, sounds like it did for you.

I know that mountain in TN, that 's where I stalled! Restarted quickly. Yes we just crawled up the hill. I usually do not drive interstates, 55 is usually tops. Interstate begs faster speeds, but mileage drops off QUICKLY.

Going to FL from Atlanta on highway 441 all the way!

Surry eye caint spayell. My phone is actin' up!

Hey Dave... Thus also comes to mind. When we had the oldcstyle ignition and the headers weren't yet wrapped, we DID have higher temps when running. We also had a ThermoQuad on the engine, the gas would sometimes boil... But that may have had something to do with the carb being worn out... The phenolic bases are finicky. Anyhow, after the AFB and header wrap, no mote heat problems!

Np, never did... And we take that sucker through mountains and way down through lowlands without ever touching the carb! Of course, I never go much over 55-60 mph... I guess the only real trouble we ever had was climbing a mountain somewhere in Tenn. Last summer... The mechanical fuel pump deep sixed on the way up. Thankfully there's an electric pump also in the line as a helper! We made it up the mountain, but c-r-a-w-l-i-n-g.... I learned a long time ago, to carry spares and SECOND spares ! Cheers, Chris

Chris,

The AFB is a great carb, BUT do you ever have stalling due to heat build up and subsequent vapor lock?

Jack,

I just looked at your Fuel Injection photos.

This would eliminate the vapor lock issues I have on a hot summer day in the mountains!

My 360 is almost identical, have an Endlebrock 4 bbl manifold and Holley 4150 carb.

I played with with the EFI idea for a minute,but my 70 year old, ASE mechanic dad convinced me to stick with the AFB and keep it clean.. Convinced me that the small hp/mpg gain wouldn't matter much compared to initiaI cost. One thing I'd like to really research would be if Rockwell ever really llbuilt a 2speed CARRIER ASSEMBLY for the rear axle and what part number it is... Legend has it that Dodge offered a 2speed rear end on motorhome chassis. THAT would really help out with fuel economy and revs at speed!
