Compression is around 10-6 to 1. Solid roller cam ,MSD 6AL. Already killed one starter,however it was only rated for 10 to 1 compression. And also sometimes while running it will pop really really loud out the exhaust. any help will be greatly appreciated! THX
If you know what you set your initial advance is with a timing light, stop the engine and rotate the engine by hand (plugs out is best) to line up on the timing mark that it is supposed to be (15 deg for example) and pop the distributor cap and see if the rotor is pointed at the terminal in the cap. If the rotor is pointing between posts or not within a few degrees of a post, the distributor is out of phase and the spark is jumping (sometimes) to the wrong cylinder. This is a common problem with magnetic pickup distributors and MSD's. Usually can be fixed by switching the wires on the distributor and re-timing the engine.
By the way, I don't care what "rating" your starter is, if the engine fires backwards with the starter gear engaged it will break something.
If you lend someone $20.00 and never see that person again, it was probably worth it.
