Well....as some of u know...my engine is making some funny noises now, but thinkin about it, i have 2 choices, tear apart my motor, buy new heads and a cam/lifter set, but it has 86k miles on it,(hard miles)......or..........i can get a brand new 502 crate motor for fairly cheap, i dont actually have all the money to buy the crate motor but if needed i can get it....the 502 would be nice but then what to do with the throttle body...can i make it work...i dunno, i really dont want a carb and cant afford aftermarket injection......what does everyone think ????
