They were certainly massive jugs, I seriously doubt whacking a Holley 750 on would increase top speed by much at all. Rev limited to 4,800 + calculating the diff ratio would give us the theoretical top speed.

dont forget they were rated SAE net, not gross like earlier models
there wasn't as much difference as you might believe, like someone else said we used to block the EGR valves with a plate, advance the timing, change the air cleaner or if were broke flip the lid and they were just as quick as XBGT's
