Re: flathead engine temps?

Even if you rotated the pump pulleys the reverse direction they would still pull water from the center of the pump (bottom of the radiator) and push it out the top of the heads.

The problem here...

Re: Holly 94 issues

Difficulty starting after a few days is symptomatic of no fuel in the float bowl, requiring extended cranking to get enough gas to the carb. The 94 is notorious for power valves not seating properly...

Re: Lowering 46 Ford 4 door

I thought I was going to get a 2+ inch drop with the new reversed eye spring in the front of my '41 coupe. What I really got was less than an inch. That is because I was replacing a tired, work...

Re: flathead engine temps?

Don't shoot the hoses. Shoot the radiator right under where the top hoses connect, and at the radiator just above the hose connection. That should show a temp drop af maybe 20 degrees.

Re: Lowering 46 Ford 4 door

Lowering shackles were very common in early hot rod days; they are cheap and effective in getting the lower look. But they really degrade handling qualities.

And if you lower more that an two...

Re: Lowering 46 Ford 4 door

Plan A, cheapest. Remove 2nd and 4th spring leaves front and back. That should get you almost an inch at each end, and not adversely affect the ride and handling too much. You may occasionally hit...

Re: Steering Wheel Covers

Ditto on that vendor. The cover I got for my '41 went on perfectly and feels great. No slipping on those sweaty palm days.

Re: A-team performance distributor issues

That is a complicated distributor, with both mechanical and vacuum advance, plus an array of springs and bushings to tailor the advance curve. It needs to be set up by an expert on a machine, with...

Re: Replacing points on 39 Ford

Re: Which Oil Sending Unit Should I Use?

Just do a test of your existing gauge to determine what actual water temperature corresponds to the markings on your gauge. Use a heat gun on the radiator right under where the passenger side top...

Re: My '34 Won't Turnover

Clean the battery terminal connections, all connections to ground, from ground to engine, and to the starter. If that does not fix it, suspect the starter switch. I presume you have the one on the...

Re: Chapter 2. Missing at part throttle.

Did two fixes on separate (I think) issues. Fixed the primary carb float level from almost 3/4" to very close to 1/2 inch. Road tested to full throttle in low and second. Wound right up to 5,000...

Re: Chapter 2. Missing at part throttle.

I run an electric fuel pump through the mechanical pump. I have the cheapo fuel pressure regulator which has worked very well so far. The pressure is set a shade under 3 psi.

First, I am going...

Re: Chapter 2. Missing at part throttle.

My rebuilt distributor came with the same calibration and vacuum brake adjustment, which I backed off to where the brake has a light drag with no vacuum.

So again, is spark advance a suspect in...

Chapter 2. Missing at part throttle.

I am going to get this old flathead purring like a kitten if it takes me a year! Which I am well into.

On my recent "Missing at full throttle" post, you helped me fix that problem. Turns out two...

Re: What’s a quick test for temp sending unit?

Swap it into a car with a working gauge and see if it registers the same as the working sender.

Can be done without losing more than a few tablespoons of coolant as you swap senders.

Re: Marvel Mystery Oil and Marvel Classic Motor Oil

It is probably a really good product for old flatheads, with increased zinc for our flat tappet cams, and detergents to prevent sludge build up. But at $9.00 per quart, plus shipping, it is a little...

Re: Autolite Spark Users Only

Wait, wait! Did these two plugs come out of the same engine at the same time? If so, the problem is not the carb.

Re: Missing at full throttle.

Cleaning the plug worked! Now firing on all 8. Smoother, faster idle and passed the throttle slam test in second gear. Almost. No missing, but started to lose power approaching 4,000 rpm. Then...

Turns out the distributor end of #2 plug wire was broken. Replaced the end and measured continuity okay with the Ohm meter. But that cylinder was still not firing at idle. Replaced the carboned up...

Re: Missing at full throttle.

Good call Bill OH. The spark plug wire for #2 cylinder with the black plug registered open circuit on my ohm meter. The others read about 4,000 Ohms per foot, which is correct for spiral wound...

Vacuum Brake on a Crab

Re: Missing at full throttle.

Good suggestion. I will test the secondaries, and if they are okay, change the distributor cap.
