Climbing Hills

Post by dunoon » Wed Oct 09, 2019 1:11 pm

I took my 26 coupe out for a test drive this morn. It's still pretty stripped mainly just the body on the Chassis. But, running it in the garage it runs good so when I drove it on the road here in western Va. where all roads go either up or down I was surprised the it had a hard time climbing a 10% grade in high, low was fine. The engine was rebuilt in 1984 but, probably don't have 2hr on it. I tried retarding the spark and adjusting the carb but didn't make any difference. Any suggestions where to start to try to get more power? I also use 93 oct nonethanol gas.

Several things. You don’t need premium fuel
How old is the fuel now.
How is the timing.
Has the carb been rebuilt.
Coils good and properly adjusted.
Engine might still be tight from rebuilding.
Are you running on magneto.

Buy a Mustang.

Seriously, it is a T. Steep hills of any length are going to require low gear in a stock T. As far as performance, 93 octane is only draining your wallet. The lowest octane you can buy will burn just fine. That said, if your 93 octane is non-ethanol, that in my opinion is preferred for any car that will sit quite awhile. I didn't always hold that opinion, but something changed dramatically about 4 years ago (at least in FL) and all my cars with ethanol, that sat any length of time, developed significant trouble including corroded carburetors. It was a mess and time consuming to fix.

have the coils rebuilt or at least checked they likely need new capps. in them and new points. make sure the timer is good
take the hot air stove off of the carb and get some old champion x plugs. these things improved the speed and hill climbing
power on my car good luck. philip

1. I see you are at 1,000 ft elevation, that will cost a bit of power
2. The cam is very likely a worn original timed “straight up “. Lots of work done on cams in the last 40 years.
3. What axle ratio are you running. Probably stock, but ?
4. What the others have mentioned
