Replace them with a 5.0.:iagree: Why waste the money on a 3.8L boat anchor, that could go into your 5.0L swap? :shakehead :screwy: If you have the motors in your garage, put it to use and throw it in that engine bay.

True, not like I need to be grenading my engine in my daily driver any way with high rpm's. Quote Selected
Valve float Reply #17 – March 22, 2006, 12:10:50 AM Valve float in my 83 T'Bird 3.8L felt just like a serious misfire and lack of acceleration. After modifying the AOD to shift at 5400RPM's, I found the limits of the valve springs, (about 5100). A call to ISKY Cams and a switch to them allowed me to rev to 6000+ RPM's, but the engine went flat beyond 4800 or so (stock 249degree cam). My car is carb'd so a change to a 500CFM Holley made a big difference, but I doubt the fuel system of a FI car could handle those RPM's. After a year of trying the impossible, I am currently installing a 5.0L H.O. engine. Good luck to you. By the way, I was told reving to 5000+ will kill the bottom end, but in my case no damage after 300 runs down the track!! Fred Quote Selected
Would my car have some sort of rev/speed limiter Reply #18 – March 22, 2006, 10:50:33 AM i used to get valve float in my 200 I6 Capri at about 4200 rpm (stupid log and worn valve springs) and it would feel like someone yanked the fuel line off my car, it would just go flat on its face. then when it came back down it would back fire like a mother cause of all that feul in the exaust.. was actaully kind of fun! hehehe Quote Selected

Would my car have some sort of rev/speed limiter Reply #20 – March 26, 2006, 03:40:23 PM I don't think Ford has rev limiters, though they do have speed limiters. My 04 Crown Vic police cruiser limits out at about 130 MPH, feels like some is trying to cut the engine off. This is done by computer chip though. I know that NC Highway Patrol has the speed limiter removed. Quote Selected
