[ValerianMagnum]

A friend of mine just bought a hughes whiplash kit ,and hooker headers , 340 4bbl aluminium intake and 600 cfm holley double pumper , no idea of what this thing can show on a dyno : 300 hp ? 350 hp ? 350 torque ? Stock heads , gasket matched , 323 cubic inch , hv oil pump and hv gas pump , what do you guys think ?.......318 whiplash premium cam kit , HUG SMC1326AL-PK

 

[273]

Stock 318 heads is the cork here for hp 300 hp give or take 20 hp.

150 to 170 hp ?

 

[diymirage]

between 200 and 300, the more involved the owner of the dyno was in the build, the closer to 300 it will be

At least put some 360 1.88/1.60 valves and a good valve job in the heads or that is the biggest restriction. How far in the hole are those pistons?

I have a similar set up. ..74 318, Hughes Whiplash cam, Doug's D453 headers, 4 bbl...
Only difference is that I home ported the snot outta my heads...
I would really doubt that I hit the 300hp mark though...probably more like 275ish.....

For what it's worth, it runs GREAT!
