Can you give me the specifics about your build? Also, any results like dyno numbers or 1/4 numbers? How is the idle quality? Also, do you have to do anything special to install a retrofit hydraulic roller cam.
I have not taken car to track or chassis dyno'ed it because I jumped right into another project after engine was installed ('88 Mustang 2.3 Turbo) .
Idle is rough due to 108 lobe separation angle. When picking cam pay attention to the lobe separation angle because it has a big impact on idle quality. I have a 2500 stall and with timing locked at 33 degrees it is very streetable. While the idle is rough the off idle response is instant. I don't drive the car daily so rough idle is ok with me.
I had to grind a small amount off the lifter valley ribs on the block to clear the link bars. Very minor grinding and the lifters dropped right in. With the small base circle cam nothing else needed to be done. I did need to run a bronze distributor gear which was not cheap.
