well my 69 chevy truck is running, sound good. It has a 350 trans and when I brought the truck the engine was just sitting in there but nothing was hooked up. So I pulled to make shure it was OK. I checked the bottom end mains and rod bearings.the standard crank had,[in paint pen ] 10 over on rods and mains. Ever thing was good so i closed it up. I didn't pull the heads but I checked the bolts. The heads have 1.7 roller tip stamped rockers? Ok after that the carb that came with is a 7150, I think, and that woulb be 650 CFM. Now my question is this, it's a truck,I would rather have a gas sipper not a gas hog. What can I do to it to help this and keep most of what I have? I dont want to put $ into it, I have a better truck to fix. any advice will be apriceated.

Hey, I have a '82 s-10 with a 350 in it and I have an edelbrock performer intake and a edelbrock 600 cfm carb on her. She's really not bad on gas. A lot better the the Holley 650 double pumper I had on it. If you could get your hand on a Quadrajet, I think that would be the way to go. you can usually pick them up fairly cheap and you'll certainly notice a difference. Try this site. It will actually tell you the proper size carburetor you should be running for your engine. Carburetor Size Calculator

thanks for the reply, and I was wondering if I offed the 1.7 rockers and went to stock 1.5 would this help? Is there any way to disengage the secondaries,it seems like I have enough power on primaries,can you block off vacume to them? Thank's againe for coment
