About Jim Holsbeck Expertise I can answer most questions on Chevrolet vehicles up to 1996, or before the ODBII.
Experience I have been working on cars since I was eight, when I started handing my dad wrenches. I did my first complete rebuild at 14, and my first restoration at 16. When it comes to Chevy, if I don't know the answer off the top of my head, I can find it out fairly quickly. (My entire family is a bunch of gear heads.)

Question I have a 1975 malibu with a 350 2 barrel, I upgraded to headers , an edlebrock performer intake, a 650 holley, 488 lift 288 duration camshaft, new timing chain and gears. when I put in cam and timing chain I lined up the 2 dots on the gears.(cam at 6 oclock and crank at 12 oclock) put in distributor so when seated it lined up with #1. from tdc with #1 valves shut I set rockers e 1348 i1257 then went 180 out and sete2567 and i 3468 ( I set by tightening rocker until pushrod would not spin and then .25 turn more). when I crank motor I can hear it spitting back trough carb like it is 180 out. I have double checked everything even as far as to break motor back down to check timing chain gears. All is correct, but it still sounds 180 out. All wires are correct on dist. (18436572). What am I missing?
Answer Dave,
It's a problem I hear a bit now and then... The problem is when you adjusted your second set of valves, 2567 exhaust and 3468 intake, you only turned the motor 180 degrees. You need to do the first adjustment set then make a full turn - 360 degrees - to set the second set. I'd loosen everything and re start with the first set and do the 360 turn and set the second and I think everything will work out. Good Luck! If by some chance it doesn't work let me know and I'll dig into it a little deeper.
