1970 duster with electric cut outs?

ok! found it! your CAM numbers are similar to my Comp extreme energy cam: XR286HR-10! make me really interested to see how mine will run, if I ever get-er done! I ordered my u-joint conversion for drive shaft, 7260 to 7290 from Doctor Diff earlier today and also waiting for my header studs to come in! I am getting closer every day!
Is your cam this one?;20-813-9? --286/294/110+4,.050s of 236/242, and lifts of .544/.541
20-813-9 - Xtreme Energy™ Retro-Fit Hydraulic Roller Camshafts
If you have aluminum heads and cylinder pressure of 180psi or so, then hang on tight man!
That's actually about 1 cam size bigger than mine, plus it's a roller, so that might fatten it up a bit more. :)
But I tell you what; forget about fuel economy....... :(
