Did you use a dynomax bullet muffler?

900 rpm

was either a dynomax or blowmaster...either way its just a straight bullet

No worries...played with the VE table some today and got it idling at 900 rpm with 14.4:1 AFR

who says you can't use 160 lb injectors with a relatively small motor

Fuel pressure is down to 45 psi, that is as low as the regulator will let me go

That gives me hope with my 160's. WOT on the dyno was one thing, but in the car at idle was what I was worried about. My base pressure is at 30 psi.

though I think due to the overlap in the cam, I can get away with a longer pw at idle than it can at 1500-2000 rpm no load....I can't get it to back down off of 11.x AFR up at that rpm...

Got a little closer this weekend...

Driveshaft is on order...should've shipped Friday
Chiseled Performance Water tank with built-in water pump on order (should ship today)
brake lines are fabbed up (double flaring tube really sucks LOL)
measured what I need for flex brake lines and ordered those
parachute mount is powdercoated and reinstalled for the last time
Bought a 54 gal drum of race fuel...

Going back to PAF to finish up setting the suspension with everything in place...looks like I will be actually able to drive it into the shop for the first time in years

should be ready for tuning shortly after

3 weeks looks to be a good estimate to start shaking down...
