We've got a 1977 360 block running on the street with the Bloomer 4.125 kit. I like it.

Running a Super Victor single plane, 950 cfm 4150 and using some modified Indy LAX heads and running on 91 octane pump gas it makes 474 LB-FT @ 3,000 rpm, 574 LB-FT @ 5,100 rpm and 629 HP @ 6,400 rpm.

The owner is a little wild and the first time it left the shop it had an ignition box with no rev-limiter. It came back in 6 hours with bent exhaust valves. As it is making over 600 HP @ 5,800 rpm, we installed a MSD 6AL-2 and I set the rev-limiter @ 6,100 (619 HP). So now, damn it, he uses the rev-limiter as a shift light.....you know.....winds it until it hits the limiter and then shifts. If I set the limiter at 7,000 rpm he'd still do the same thing. It's just one of the many small reasons I've decided to not build anymore engines after I finish the ones already here.
