Running a stang in mexico

Hmm...

Your photo looks great, front wheels up, nice 60 ft time, not a bad 1/4 mile time either. But 96mph in the quarter is really slow, that's about what a stock 5.0 will run.

Did you run that time in the 120 degree heat? That may account for the low top speed. I've watched a lot of dyno pulls and with those heads you may not be putting out more than 265/285 hp at sea level in cool air.

Do you have access to a chasis dyno down there? That should give you a good idea how your engine is performing, then you'll know if you should be looking at clutch trans etc. or engine.

Also compare speeds going down the track to others running a little faster than you. Maybe you can pinpoint where where your speed is dropping off.

By the way, I've seen charts which use the engine displacement and the RPM to calculate the CFM required for the engine. I think 750 cfm is way to much for 5.0 at 5300 rpm
