DeskTop Dyno
If i remember correctly (i bought the 2003 version), it cost me $45 at large book store (maybe Barnes & Noble ?). I assume the newer versions are even better (i read awhile back about one of the newer versions having a much larger database with large # of cam specs (cam cards) from multiple manufactures, etc)(this one still works perfect, even though it's been through Windows 95,Me & Xp). I also assume that all major book stores either stock it or could order it...check online. Maybe even the "Checker Auto" type stores might carry that kind of stuff now ?? It came with a very informative book,on the subject of dynos & engine effeciencies in general. Way worth it.
Looks like my new 454 (built for low-end grunt and fuel mileage) (LOL, fuel mileage on a 454, LOL) (9.5:1 flat tops, almost zero head space (good squish), pocket ported oval truck heads, heads angle decked to even up and get to 9.5:1 minus light relief around valve areas, (had to have intake manifold angle decked slightly to get everything to match perfectly) Edelbrock Performer intake (intake, heads & headers are all port matched)(head intake ports were not hogged out, but, smoothed up (same with intake manifold), then both ports lightly textured with small wire wheel (VERY light on the aluminum, lol), Comp Cams x4 254H-11 and matching springs,etc..(i ran a butt-load of different cams through the dyno program), the chambers & piston tops polished & a cleaned up "Carter" branded quadra-jet (780 cfm, i think ??)... gives about 520 lb/ft at 2200 rpm (at flywheel) (560 lb/ft at 3000 "max"). HP goes flat 4200 rpm and starts falling off after 4500 rpm..but there is still a lot there at 5000. I expect no worse mileage than my 400 sb with same carb, no headers and factory duel exhaust ????? but, a buttload more grunt... we'll see, LOL
