<<<Will,

Be careful there..... If you have cleaned up the heads and are using a
decent intake (M-1) 29 lb/hr injectors is all you
need (310 CC). That's what we are using. I hope you are not using the factory
rods (A-type or Magnums), you really
need to step up to either Eagle or Manley's. Factory rods are not up to
snuff. What pistons are you using????? If they
are Diamond's pistons, then you have a static C/R with the Magnum heads right
up around 12/1 (pumping compression) above 200 PSI unless you have a cam with
a hell of a lot of overlap. Even the soon to be released
KB pistons, static compression is up to 10/1. If you are actually going to
use a blower, use one of the after-market
injector plates and computer (Vortech, Paxton, etc). Smaller injectors (29
lb/hr) will give you a better spray pattern and
the plate will give you better fuel control under boost. Good luck with the
head gaskets.

Frank,
I am using MP connecting rods with MP pistons that have a shorter total
height. The cr is around 9.95:1 (was higher, but the head gaskets we are
using are thicker fel-pro's than normal and the pistons were given a slight
shave on top). The heads are the MP aluminum Magnum heads that were massaged
a little more along with crower 1.6:1 rockers and triple springs. The valves
have had the stem shaved down and the heads swirled. I am going to be
running a Comp Cam pn 20-604-8. It is a 264/274 adv 210/220@.050 duration
with .512/.512 lift with 1.5 rockers and 112 lobe sep. My machinist figures
that lift and duration will work well with the boost from the sc. I believe
it will also, esp with the head work and intake we've done. Oh yeah, we are
going to run the MPI intake. We were doing so cals on the puter and it spit
out 35 lb her injectors, but we figured 36 would be good. Oh yeah,
everything is forged (pistons, crank, rods, etc.....). I got lucky in the
stock market and decided not to skimp on anything. Anyway, which blower?
PowerDyne or Paxton? Novi 2000......sweet........
