Bought the XB3 (B303 cam) from Ford, $2900 delivered to the door. Demon 650 on an Edelbrock Performer RPM, MSD ign., and love it. Fires off before it goes 1/2 revolution, happy on 91 octane, sounds better than any 302 has a right to, and will get you wide-eyed thru the first 3 gears.
Oil pressure steady 40 psi when hot, never been over 190 degrees even in traffic.
Still have some tuning to do; total timing still at 30 degrees and Ford recommends 36. Still - very happy with how this has turned out. Rev limiter set at 6200 per Ford, will pull to limiter in every gear - but havent tried it in 5th yet.
No doubt the 351 is a better showoff....from a 1st gear roll there is no wheelspin, just squats and hauls a$$. Very impressive for a 9:1 motor. Change the
oil and turn the key - this is great.
