7747 spd limit first, trip timers next?

[Mike Rolica]

Whach mean??  The problem I have is that the motor is flowing 460 cfm max
and that is at about at 3500rpm... stays at 460 until 5000rpm then it starts
to go backwards.  I'de like to try things in stages.  Ie go to 52 mm tb  by
honeing mine out and making bigger throttle plates.  Don't wanto change
torque cure too much either.. just bring everything up.

	Keep the sales receipt, and measure your performance BEFORE, and
AFTER, you
	might be surprised with what you find!!.

	Have saomething else in mind?  Heads flow better that excellent...so
restriction is between head and tb.
	Will need to do more work on bin though... had to do some last
couple of days.. changed from 2-1/4 dual exauhst to 3 inch with x pipe, dual
cats and  3" dump out valves.  Screwed everything up.  Had to add more fuel
from 2000 and up. Losa more power!  

	Problem I have is that when I put it in 4x4 it dies if it is
idleing.  Think it is related to the map cause front axle engages with
vacume actuator.. get real lean spike on diacom when I pull it in to 4x4....
Any suggestions?
	Course CSH, HQ has the equipment for doing said testing (wrenching
not
	included).
	  Hmm, nother road trip <g>...

	   For a higher then stock flowing base I've mentioned what GM did
to the
	cross fire for high RPM breathing.

	What was that??
