Signs of valve float or fuel starvation?
Doing some fine tuning on the 350.
I'm getting some light to med sputtering at high rpms, around 4800 and up.
Just wondering what some quick way to tell if I'm running the bowls dry or it I don't have enough valve spring pressure? When should this cam be done? Comp says 1500-5500.
Performer RPM non air gap
Holley 600 v.s. (1850)
Mech fuel pump- Z28 spec supposedly
Orig 327 2 bbl fuel lines.
ported 041 heads with 2.02/1.6
1 5/8 headers
Comp HE268, 218 @ .050 and .483 lift (1.6 rockers)
TH350 with 2000 stall t/conv (Hughes GM20)
I have a valvespring pressure checker, and have on eof those cheap vacuum/fuel pressure gauges I think I can plumb in and tape to the windshield and do a run while checking it I guess, but was hoping for what is more of telltale signs of either fuel or valvespring.
Hope I described what I'm trying to check out......
