Ea81 Cam

[Crazyeights]

I have already done the EA81 performance build - pretty much every mod you can including LOTS of head and FI work. One tip I can offer about the cam. If you are having the cam reground - start with a Hydro cam as it has a larger base circle to work with, even if you are building a solid lifter engine. This will help reduce valve train noise. Once you re-grind a solid lifter cam the base circle is reduced enough that when combined a reface on the lifters, another .020" off the heads, .005" off the deck, ect you end up with incurable valve train geometry problems = NOISY!

 

When built and tuned correctly the little EA81 PULLS HARD up to over 4000 rpms and still produces pretty decent fuel mileage. I would recommend doing it again if you can find a core worth building. Good Luck and HAVE FUN!
