SCR vs DCR

91? with that you prolly can run 87-89...I run 91 with 8.3-8.4

is this an iron head motor? just trying to keep apples to apples...

im going to finish this round of tricks and then get my roller rockers 1.6's (.540 lift)

re-tune and dyno it, track it...

then im gonna play with cam timing to see what might be hiding in there as far as cyl pressure and DCR...
