So when i accelerate hard after like 3 grand rpms theres this rattle, my pops says its early ignition but im not thinking it is, anyone else have simmiliar problems, im sorry i dont have alot of information but its hard to get out and look at my engine when im doing 50 miles per hour

Does it sound like marbles rolling around in a coffee can? What's the timing set at and what octane are you using? What kinda shape are the plugs in?

I would say your timing is too advance...also do what pro said.

Yup,sound like timing,back the timing down a bit.
