The overhaul manual for the T170 trans. calls for "Full Synthetic Manual Transmission Fluid". Ford sells it under the Motorcraft brand and I get it at the local Ford dealership. However I know several folks use 90 wt. fluid and it seem to work ok, I have noted that the trans. that I have...

I agree with the above comments. However on simple non turbocharged aircraft engines a lot of engines are equipped with a single EGT probe for one cylinder. Certainly not as good as a system that has probes for all cylinders but much better than nothing. Lean the mixture until you are at max...

I can see where an air fuel gauge would be beneficial for tuning an engine. Would an exhaust temperature gauge accomplish the same thing? I happen to have an EGT in my shop that I removed from an aircraft engine.

Thanks for the responses. After thinking about it more I guess I will just stay with the 4” stroke Mercury crank, 3-5/16” bore and mill the heads for an increase in compression. This engine will be in a 41 coupe used as a daily driver. I will stay with a single carb. so the engine will have a...

I am thinking of building an 8BA with a 4-1/8” stroke crank. I have a 4” mercury crank to offset grind and a complete 21A engine that I can pull the rods out of. The rods will use floating bearings and the mains will be inserts. The question is, what pistons do I use? A local old timer told...

Re: Id this 4spd trans in model a? It's a Tremec T170RTS. Used in some ford F150's 1984-87. The ones that I use are 26% overdrive in forth gear. They were also made with other overdrive ratios but the 26% works well for me. I put one in my Model A (stock 4 cyl.) and also my 1933 pickup...

Anyone know hot to contact Bubba's Ignitions? Been trying to order a distributor for a week via email & telephone and can't get a response.

I have a T170 that I want to use but the overdrive is 41%. I have been trying to find a 26% cluster gear and overdrive gear for some time now with no success. Do any of you know where I might find these parts?
