Just saying Hi, and that I am new to this site. I daily drive a stroke but my toy is a 79 Ford F-350 that I put a cummins in. Running a 4R100 in it with a 3 disk suncoast, trasgo shift kit. 370 injectors 4k gov spring, 16cm housing on hx35, #4 all the way ahead, motor has the 160 pump, 191 dv. I shimmed up the over flow so I could hold my fuel pressure better, and un-hooked my lift pump and put my stock superduty pump on it. Seems to hold fuel pressure better, 40 psi idle, pulls down to 20 psi wot. My goal is the 500 mark, and I am at 338 right now (dont know if poss with 160 pump). So I am looking for some advice, on how to get there. Thanks you guys have a nice site.
