Anyone running Mach 5 injectors? I need to clean up low end smoke (Extrude hone 175's) and was thinking maybe a F1 injector may be the way to go. I tried a set of DDP 150's, they were great for smoke control and Egt's...but the power wasn't there. Here is the combo

160 pump
4 Gsk
18* timing
191 Dv's
ported head
Bigstick cam
64/71/14
full fuel@25psi

Thanks guys
 
I'm using Mach 6's right now @ 22* timing. Anything over 22* and they haze pretty good at idle. At 22* they are sweet. I tried DDP 250's and they are too dirty for street driving for me.
 
My 250's are pretty smoky also and they seem to make the engine run louder with the high timing. Gonna try something different here shortly.
