Ok all I haven't posted any updates on my Demon for a while, been too cold to do much. Here is what I am thinking of putting together for the engine combo and I wanted to get some input from members. The car is primarily being put together for street duty, with a trip to the strip once in a while just for the fun of it. 440 stock stroke .030 over running ross pistons. Block machined to give a true 10:1. Eddy 84cc heads not too exotic. Torker 2 or ??? on intake, Demon 800 or 850 vacuum secondary, forged crank, H beam rods with rotating assembly balanced. 727 tranny with torque converter and rear gears to match cam. Now the cam is the one I am tossing around. Wanna go roller. Hyd or mech lifters ? Here is the cam I am looking at. Want to know what you all think and what intake to go with it torker 2 or performer rpm? I have never run a mech cam and this one I think would achieve what I want. I plan on running schumacher tri y's. Please keep in mind I am NOT looking for all out performance but a good running street engine that'll open up when the loud pedal is mashed. I do not have any power accessories ie p/s or p/b. Of course matching valve springs etc will be used. Will it make good power and torque for what I am planning on? Lunati p/n 60331 rpm 2500-6600, lobe separation angle 110, adv duration 267 int 273 ex, duration @ .050 int 237 ex 243, intake lift .566 exhaust lift .578. What special requirements are needed to run the solids as far as block? I know I need a thrust button for the cam set up for the proper lash on the cam and a bronze oil pump drive. Will this combination give me the aggressive idle also? Past experience was a purple shaft 292 509 in a big block. I wanna do this right the first time and put together a reliable but fun combo. Thank you all for feed back in advance. Suggestions are welcome and appreciated.Sorry long winded but I wanted to give all the info I could Brent.
