Hughes Whiplash Camshaft

volaredon said

I would have to jump over to teh /6 site to get specifics, but I was looking at going with Oregon's #819. I was also looking into possibly one of a couple of "Howard's" cams I discovered on Ebay.
I thought the #2106 was a hydraulic grind? I am staying with solid lifters.

Ok found it:

Oregon's grind #819
219/219 @ .050", 264/264 adv, .437"/.437" lift, 110 sep

The 2106 is very close to the RV10 and is what Ken at Oregon recommended when I talked to him.
210/214 @ .050”, 254/254 adv, .434”/.444” lift, 108 sep

Basically the same grind. The 110 sep will give you a bit more at high end (if the rest of the build is not choking it off there) and the 108 will give you a bit more low end. You can see that in the model results below.

Dart Build in the graph is as follows:

• 8.8: 1 compression
• Oversized Valves
• Dutra Duals
• Collector behind the cross member for the 2 banks (BIG BANG FOR THE BUCK OVER HEADERS for low end torque)
• Offy Dual Carb (just modeled total CFM so a 4 barrel with the same CFM would model the same).
• Low restriction exhaust (second order effect)
• OC 2106 or OC 819

I can't get a good image to upload right... So the closely spaced lines are the OC 2106 vs the OC 819... little difference. The single low line is a stock 1968 225. The next better pair are the Super 6 with the 2 different camshafts and the highest lines are my Dart build.
