430HP? This must be with headers and a good exhaust system.

Yes...headers on the dyno...stock 4492 Holley, factory distributor, fresh rebuild and maybe a couple of extra cubes [img]<<GRAEMLIN_URL>>/rolleyes.gif[/img]

Like Tommy says headers, a curved distributor, some good Eric J. carb work and a good valve adjustment sure, why not!
That is what we did in the old days to run mid to low 12's in those L78 novas and camaros.
Add a 4.56 gear and some 7&quot; cheaters and you are golden.
Who cares what it dynos? Tha drag strip is your dyno!
