still looking for something to build. im starting to shy away from my original bigblock idea after going thru some cost analysis. i still want something odd and badass. is there a program i can get that i can set up like a 400 block or 350 and go from there with pistons heads and induction. i had a desktopdyno program but i really hated it. id like 4-500 hp (dont we all) but not just strait up power. a nice curve in the powerband so i can be streetable yes slam corners and straits

Not sure which dyno program you had before, but here are the top 3

Build a 400 with AFR 195's, 9.5:1 compression, a hydraulic flat tappet (or hyd roller if you can afford it) and an Air Gap intake and 400+ HP is as easy as falling off a log, and it will be extremely reliable. Even a stock crank and rods with cast pistons would work at this level, and would be (relatively) cheap to build.

Are ther eany free online type software out there that does similar things as the ones listed in the links? Just curious....

rustbucket i like the idea. i really have been wanting to try out the edlebrock proflow efi system. basically the same as an airgap but with the fun and reliability of multiport fuel injection and a 1000cfm throttlebody. some of my friends keep throwing together combos that can make power but dont last more then a few runs, or run decent but are more dogs then a pack of pitbulls. ideally i like to ket the trottle out and have soem fun. if/when the car ever sees the track i need it to stay jusr a tenth over what is required for a cage:cool:

id also like to know if there are any free programs.
