What is your opinion on the SE 585 cam with the new 117 bolt-in street kit? I have ordered one and it comes with 259e cams but I like the the low end torque I get with my 255 cams. Don't mind losing a little down low but don't want to be disappointed after the install with the 259e cam.
The SE 585 will be a torquer similar to the SE255 in the 110 but more due to the added displacement. In other words similar shape of the curve just higher everywhere. One other similarity now your peak HP without head work will be in the 4500 rpm range. At the stock 117" compression ratio which I figured at a nominal 9.8:1 this combo would be very octane friendly too.
The 259 is a late finisher but in a motor this big would have good torque down low better if the compression was raised. Even so to get the potential out of the 259 the heads will need to be ported, a larger TB and injectors. If I was going there I would use a different cam and target 130/130 and not dabble, and of course in the middle of this work the crank would be trussed up and trued and a clutch purchased.
One is the Ying build one is the Yang, choose your option.
