I dunno Bern, that estimate sounds real shy on power for a whipple setup. Rob Stringer was making over 800 hp with Whipples on his 500EFI's with stock compression and an off-the-shelf 741cam. Also that's with steel heads. He even made 900 hp on one pull.

Bern, I found some more info.

If all they did was bolt a set of 2.3's onto the 500efi's it'll make 700 hp @ 6 lbs boost.

If they went with a bigger cam, ported heads or alunimum heads you're looking upwards of 800 hp.

The sit-down OL that had a setup like that made 900+ hp on Zul's dyno on pump gas!
