Re: swapping from a NBS 4.3 to a V8
update - the part that was wrong was a fuel-rail fitting, and it was from S&P, sister company to SPE. not a problem though, I have gone to all AN compression fittings and we've tested the system to 120 psi on both feed and return. we had to convert from the dead-head style fuel rail that came with the 01 LS1 we're using to a return-style to match the fuel system in the truck, with a new adjustable regulator for future engine upgrades. the engine is in and all the wiring finished, except for the fan setup and some modifications to the starter-kill (thanks a lot J ). I have to finish some cleanup with harness routing and get everything put back together, mount the fans, assemble the new WSM cai, finish the a/c lines and get it charged, build the dual exhaust, and then get it on the dyno ad make sure the computer is sorted out. the good news is, we fired it last night - after blowing out all the crap that has settled in it for over a year and burning in the headers, it settled into a nice easy idle with no hiccups. timing looks good, temp looks good, plugs look good - Ill offer some more once I get it completed, tuned, and street-tested
