Bad batch of Edelbrock baseplates
Does anyone know about when the supposed batch of bad Edelbrock baseplates (3860) were produced? I've been reading of recent problems with the base such as leaking and holes being drilled too deep etc. and I'm trying to figure out if the one I have is one of them. I bought it unused from a member here about 3+ years ago and now am concerned it may be one of those defective ones. Thanks in advance.

There was another one recently on the General Engine/Tech board.

Eddy may be able to tell you
Take a flat edge to it see if you can mock it up on someones motor if thats possible. Holes easy to correct.
Sometimes the molds get old. Ive worked on a # of their new BBC intakes and the ports need a good deal of correcting. Easily done but still
Nothings bolt on lol
Good luck!
