WyoRoadDog, Thanks for the link, I've been to that site many times before, I don't know how I could forget to check it
Jake, yes you sent me that link before but I couldn't find it, I found it just now, I tried the upgrade back in '03, bought the stromberg to holley adapter and the carb, put it on and got it running but the truck smoked like a freight train so I took it off and put the old carb back on and stashed the holley away, now I have to to upgrade, I may be going with a 351 intake now.
Thanks.
