ok so today i reinstalled the steering and filled the transmission with the gear oil, and took it for a test drive it ran nice engine is strong but its not throwing me back in the seat like i expected from this v8. i feel as if my infiniti g35 sedan has more ass then this does. at least i feel the power more from my G. inside the mustang is a decent size cam im gonna say its mild, and im sure the gears are stock, i only say this cause during the burn outs today only one wheel was spinning. during that event the drive belt went out on it and then it started leaking from the over flow tank on the radiator. the fluid in that is a rusty color i plan to change this fluid. but this v8 was weak i thought it was gonna be like balls to the wall. its a carb set up and its a edlbroch and a whaylin or however its spelled intake. i really would say that my timing is off and that the carb is not tweaked right i live in the hagerstown area. if anyone knows where i can take it to for a good price to get properly tuned. but i think its just a weak motor and has no power. the later models put more power out. i know this so if i were to find just the later block would that be a simple bolt up? and i can use mainly most of my current set up for hitting the 400 hp numbers? 650 edlbroch carb and 8mm wires. i would like some imput is all thank you!
