alright guys i put a new wiseco piston in with the stock compression specs, it also has a new timing chain, but now it wont start, it turns over perfect and has a brand new plug in it an is gettin fuel, it'll pop every once in a while but nothing more. could this be the timing off?

 

Yes, that's what it sounds like - cam timing is off, a common mishap whenever R&R the cam chain.
