i have a 81 k10 4x4 when i leave from a stop sign or a sop light i hear a rattle like noise until i hit about 5mph or so, it doesnt make the noise when im in neutral or park while reving up the truck.
any thoughts on what it could be?
Ok so I have a 1980 c35 with a 454. I'm not getting but a mile per gallon.
My fuel tank is a 5 gallon gas jug at the moment. My fuel returns arnt getting any gas threw them and I have my number 3 spark plug gas fouled.
I'm looking around for a new carb. I have a 80 c35 7.4l. At the moment I have a 700cfm quadra junk ( I know it's to small). I'm thinking a holly 800 or 850 cfm. What do y'all think?
