D&D should have the cut specs for said unit, my 87 received one when it was a 3.5. the original cam did not have much of the lobes so a new cam really did pep it up. now in the middle of much needed resto and upgrade will recive a 4.6 with a cam.
my 95 had a blown engine at time of aquisition so I installed a custom 4.6 with a crower cam... off a light I can chirp the wheels and it pull strong from 1200 rpm all the way to nearly 5800 rpm.
when the engine was dyoned it pulled close to 300hp at the fly wheel.
in reality I did not have basic numbers on which to begin, but the dyno operator seemed impressed by the resulting numbers.
you know how it is this side of the pond, if it isn't gm ford or chevy you cant find performance parts and when you can perform, the hardcore belivers have a hard time accepting.
one of the lro monthly magazines in the uk is advertising the jag engine into older rovers (D's, Classic and p38 Range and discos).
4.4 300hp normal or 4.2 500hp supercharged.
they have pictures and it looks clean... Im sure it will set you back a few bucks thou.
