Do a compression check first . that will tell you if your mechanical stuff is OK. Look for 120 to 150 PSI on all 8 cylinders. Then check the accelerator pump on the carb. It will give all those symptoms if it isn't working. If you get a good strong spray down the intake then go to the engine forum stickies and look for engine timing . That will give you a step by step guide to timing the engine. It may be listed under engine FAQS. I looked it up for you.....http://67-72chevytrucks.com/vboard/s...d.php?t=290498
