Tunnel ram cam?!

LOL. The cam is the number ONE killer of TR performance. If the cam is correct for a single 4 it damn sure isn’t even close for a TR.

I guess I must just be lucky then..... because when I did the back to back test on the dyno, about a dozen times, the TR always made more power.
And not once was the cam made “specifically” for the TR.

I’ll just keep doing what I’ve been doing.

Most of these “mid-level” TR’s, like what the OP is showing pics of....... actually peak at a lower rpm than the typical “race” style single plane.
