    Hello all,

    I've always thought that a 70mm is about all you'll ever need for a street car. Any of you run a 90mm out there?

    An n/a 5.0 has no need for a 90mm TB. I think the box r's have 90s and the downs box may also but those are meant for skyhigh revving motors and boosted cars

    unless it has a power adder (supercharger or turbo) then it will be over kill.

    Might as well throw a 4" exhaust on there as well and throw all the low end torque out the motor.

    Unless it's a 408stroker with a big turbo making 1000 hp no need for it.

    ^ I'm just talking about 302s. Well aware that there are many N/A motors using much larger throttle bodies than what is considered "big" on 5.0 (ls1 is a good example)
