my 00 gt is knocking like crazy,so a friend of mine from a ford dealer gave me a motor from a f150. it was pulled due to carbon build up on the pistons and the owner went the cheaper route and got a junkyard motor rather paying the dealer labor rates for the original motor.Anyway all i have to do is clean the top of the pistons and put the heads back on to have a good motor.so he says.u can see where the valves hit the carbon lightly. OK my question is, can i use the comp cams from my windsor motor in this romeo?? whats the difference in the 2 motors other than the intakes? i also got another complete motor out of a crown vic that was said to be locked up,would it be worth it to tear down to maybe fix back as a spare? what will inner change between the windsors and romeos.....thanks alot guys
