motor swap complete, now I could use advice on backfire.
I pulled a motor out of a 2007 crown vic with 39000 miles. Swapped it into my 2001 mustang gt (used mustang intake and throttle body and swapped to crown vic motor, yes I got new gaskets) started it up, idles fine but when you rev there is backfire. When I get it on the road it runs like a pig. Sluggish, feels like not enough gas. Can you swap those intakes with no problem? It bolted right up lol btw I know I'm getting a power loss by switching to cv motor but it's not much and there are plans for this car In the near future to gain all power back plus some.
