Subject: [Fot] Performance cam for a street TR4

From: Chuck Gee via Fot <[email-masked]>
Date: Wed, 19 Mar 2025 20:25:26 -0400

So it looks like I have to rebuild the motor on my street TR4.  The current motor is stock and could use a little more performance.  Does anyone have a better than stock cam they are willing to part with?  Preferably something I can use with stock valve springs, but that’s not a deal breaker.  

If you don’t have a cam for sale, do you have a good recommendation?

Thanks,

Chuck

Hi Chuck,
 I'm sure you=E2=80=99ll get plenty of recommendations, but honestly, if =
all you=E2=80=99re going to do is a stock rebuild, then a different cam =
won=E2=80=99t do much other than screw with your powerband. If you=E2=80=99=
re not going to change anything else, the only worthwhile change is =
displacement, and even that is of limited benefit.   =20
