it should keep pulling past 6000 rpm, not sure what happened. Im going to get a new pump and valves springs. On the street with 3.23 gears im very rarely above 5000 rpm so I had no idea what it was doing
What intake are you running? Are you going to do an inline or an in tank pump? Still decent numbers for your fueling issue. I hope to have my 6.0 installed in a few weeks. I was going to do the turbo, but changed my mind and doing a 6.0 with l92 ported heads with holley hi ram intake which I hope will clear my cowl hood.
stock truck intake, just a single external 255 walbro, sucking from the stock feed line, might ty and rig up an intank. the 6.0 with l92 will be a good runner, thats what I had before this.
with the ls6 cam and 3.42 gears it ran 10.6 in the 1/4, now with the ls9 cam and 3.23 gears...??? feels faster. 3400 race weight, th350, 8" dot slick, stock suspension.
