Not sure how the aftermarket Duraspark distributors are.... Most on here complain about the later ones with the TFI moduleI would actually very much like to try DUI but their wait time is 8 to 12 weeks.
How did the quality of the LMR distributor seem? Did it seem to have proper endplay and most importantly, was the installed distributor gear height within spec?I Purchased what you need from lMR... My car project is not done yet so the engine has not been started or run yet.... No recommendations as of yet..
While looking through the Summit catalog remembered one of the ;problems with an HEI or Pertronix was stock Air cleaner clearance....
Here is the distributor...
No idea.. If you give me the specs I will check it..How did the quality of the LMR distributor seem? Did it seem to have proper endplay and most importantly, was the installed distributor gear height within spec?
I always thought it was measured to the flat machined pad on the bottom of the gear. This is the surface that rides on the corresponding machined pad down inside the engine block. Its my understanding that the two surfaces ride on an oil film. The helix angle of the gear in rotation pulls the distributer shaft with the gear attached down to ride on the that surface in the block. If the gear is too low on the shaft, tightening the hold down clamp will smash the two surfaces together and cause damage to the gear and block. If the gear is too high, their is too much gap between the surfaces and the distributor itself might be damaged. The end play in the shaft, dictated by the collar pinned above the gear, is there for wiggle room/manufacturing tolerances and to allow the cam rotation to pull down on the shaft and gear during rotation, if that makes sense. At least that's how I've read it in my research. I think there's some Youtube videos on this too as well as other articles on the net.2. the pictures show measuring to the bottom of the teeth of the drive gear, NOT the flat area at the bottom of the drive gear.. Do I have that right? Big difference here...... There is a small flat area on the teeth, also a bevel.. so it makes this interesting....
