I have h/c/i with 24s I'll be getting rid of for Siemens deka 80lbers. I'm using quarterhorse/be I'm told I can tune them for near perfect driveability. I'll probably go with the tre 320 fuel pump as while my walbro 255 is just too loud for my taste. Overkill yes but I'll be adding boost soon and with modern tuning it shouldnt matter and I won't have to upgrade later.
