well my car is a 89 lx but i have a carbed 308 in it , the boys in the 5.0 fourm mostley mess eith fuleinjection , so i thought yall might could help, what rvt seleant is the best for intake ?, i have the organ/red kid but its leaking oil

 

The RTV Blue is the best for the corners of the intake. I assume that is what you are asking, as your use of the English language leaves a lot to be desired. In addition, I don't know of a 308 engine that Ford produced in the 80's. Perhaps you mean a 302?

 

probabky something lie a .40 over 302 glen

 

I use the black high temp permatex and I don't use the supllied cork or rubber gaskets for the ends. Just run a 3/8 bead of silicone in place of the gaskets and you will have a lot better luck keeping it from leaking.

 

471? What heads are you running?
