Ok here's the deal. I have a set pf AFR's 190 and the comp cam XE 236/242. The first problem is that the rockers are extremely hard to adjust. When they are adjusted it pops(Back fires) at idle. I've torn the car down once a checked cam timing, then replaced the opti and tonight I put my stock rocker arms back on and still the same. It is even worse with the MSD hooked up. I've checked fuses, injectors, fuel lines,plugs, wires etc..Has anyone come across this problem? Do you think I need different length pushrods? PLEASE HELP ASAP. My car has been down for 45 days now, trying to resolve the issue, with no sucess. By the way it is a stock bottom end LT1.
