Just out of interest, Im getting a 3.9 EA rebuilt with extensive mods; stronger valve springs, bronze guides, larger valves and major port work. [Gulp!] After the change over the other head is for sale...... every part 8000 kms old.
Then found this bloke who designed a cam with a slightly shorter duration and a bit more lift than the Crow stage 2 cam. The theory being that the valve opens and closes quicker, and the duration is not so long as to give a rough idle or trouble the computor. Anyway, I think Im his second guinie pig.
Anyone have any opinions on the Crow cam as the news Ive heard isnt too flash.
