x2 100% the 318 whiplash roller cam isa killer street cam in lopo SB also.

I have 400$ invested in the 440 whiplash cam/springs/lifters/timing gears to go in my stock 78 440 from a 1.25 ton chassis motor home.

in the 88 swb truck the stock motor is a beast with nothing more than rpm intake/q-jet/center dump manifolds/stock low stall TC-727 turning 3.91sg and a 29x15x15 M/T tire.

pulling 13 mpg as a daily driver turning 3.23 gears/29x15x15

adding headers/fresh 452 heads/whiplash cam/stock high stall TC in the 727 TF-2 shift kit.

if it does what it did for my roller cam 318 in the 85 stepside, I will be more than pleased with it.

I hope to have the whiplash 318 in the stepside back on the road soon with the nv4500 5 speed conversion in it. whiplash + 5 speed + 85 stepside =

I have 2 whiplash roller cams and a 440 whiplash flat tappet going in soon.like they said... idles like a funny car and smooths right out around 1800 rpm for daily street duty redlight to redlight action.

found myself having to play with the whiplash SB roller cam stuff first..the cam break-in on the 440 has me a little...
