Re: 2v vs. 4v 4.6 engines?
Yeah, your sold, I'm gettin bought. My 2 valve chatters around 3K then settles down for the rest (tuned). Still, now I'm tinkin of hardening the heads, that means UPGRADE!!. My motor has 97K. I have built tremendous rear end torque according to SCT, but I'm not believin it though. MTF.
Good luck man. love it alltheway.
