Im curious what the top speed of a SB 408 might be, forged internals with H beams, Air Gap, Solid Flat tappet 246/252@50 with 600 lift, Dana 60 3.54 gears
Cruise speed or trap speed? 105-110mph is about it for cruising with good stock suspension, I've been to 125-130mph a few times but thats only for 4-5 sec at most. You could probably go 115-120 with that cam and 3.54's.
