410'

X3 on the heads. Take advantage of technology.

You should up the compression ratio to at least 10 to 1 but could do 10 to 1 and still run pump gas.

You can run a 3500 stall on the street anything less than that and it will fall on its face off the line. That is if you plan on spanking that snot nosed brat mustang driver next to you that just needs to be taught a lesson.:headbang: 3.91 gears are fine for the street.

I don't know about 500 but mid 400's and alot of torq.
