Don’t mind the tach, cuz it’s way off lol. Runs 75 mph around 2200-2300, and, oddly enough, the speedometer is spot on with 35s. Pulls the Skyway bridge in OD and can accelerate locked up in OD up that bridge no problem. Torque is handy! The old 350 couldn’t do that.

Is it me or does that thing look might dry? Mighty glad that you got her up and running and are happy with it.

Yeah it’s dry because that’s post brake cleaner haha. She’s running really well! A couple hiccups, but nothing terrible. Had the crank sensor go out today when the fiancé was driving. Matt went to the house and put the one in from the 350 and it worked. Got down the road from Largo, hit Bradenton, and that one stopped working too lmao. Hobbled over to Advanced and picked up a new one. Made the rest of the trip down to Fort Myers. It does have some bogging down issues at low speed and light throttle sometimes, but who uses light throttle anyways?
