**600hp sbm block limit? Or is it bs!!**

nope looks like the same girdle Hugh's sells i have one in my 426 small block ??? i have a question for mad dart is your engine race only or street engine .????

Mine will be street/strip. Drive to the track, nock off an 8.50 at 160mph then drive it home at 1800rpm with my 2.76 or 2.94 gears in the rear :D

That Girdle MRL is selling looks noting like the hughes girdle...........The contact area on the Caps is probably less than 1/2 on the hughes part.
