I have found .025" and .050" flywheel shims for the 8BA engine. I assume they are used to make up the difference in flywheel height after the wheel is surfaced. Are these commonly used? If so, how do i measure to determine how much shim i need? What would be the correct dimension? Many...

I have 2 8BA blocks that were stored for about 3 years after being bored without being assembled. (I am the guilty one) I used steel wool and oil to remove as much rust as possible, but there are still some rust stains that resemble shadows. No pits that are big enough to feel with a pick or...

I'm preparing to install T5 5-speeds on two of my 8BA Flatheads to be used in F1 pickups. I can use the short pickup bellhousing and an adapter made by Speedy Bill (RIP), or Offenhauser. Another choice would be to use the Hogshead adapter from a large truck and an adapter. My questions are: Are...

I am curious. What do you guys think about re-seating the steel needle into the brass seat on these 94/2100 carbs so that the needle/seat could be reused? The ones i remove look just like the new ones i buy. 2-3 light taps with a small hammer and testing with vacuum or pressure is what i am...

My 8BA block has pits in the surfaces between the inlet and outlet holes of the water pumps. Should they be filled and leveled out before new pumps are installed, or should they be ignored? Thanks in advance, ...jack

I know nothing about Stromberg carbs. I recently read that a 81 flows 125 CFM, a 97 flows 155 CFM, and a 48 flows 170 CFM. Is this correct? If a 97 has a .97" venturi, does an 81 measure .81"? Then what are they measuring on the 48 to get 170 CFM? If the venturi on a 48 is not .48", then what...
