Woo-hoo!! Another cam-choice thread!!
I'm still dithering on the cam choice for my 390 build. To reiterate, it's a 0.030 over 390, Probe flat-tops; Ed #60069 heads (10.25/1); port-matched to a Streetmaster with the plenum mod; 750 QuickFuel 'Slayer'; POP adjustable rockers; Duraspark distributor that Faron's re-worked; MSD streetfire box; C-6 with 2500 or 3000 (depending on which cam I end up with) TQ; 3.89/1 gears; 31x12.50-15's; in a 3,500# F100 shortbed (currently in a state of disassembly -
http://fepower.net/simplemachinesforum/index.php?topic=2151.0 ); it has power brakes, but I can use a vacuum pump if I need it; for shows/cruising.
I'm going to use a mechanical cam, and I'd like something with some nastiness at idle, while still being decently streetable. Neither 1/4 mile performance nor MPG is a concern, but something that sounds nasty is. I'm 60, and should know better, but..
I already have a Comp 282S, but am wondering if it's going to be TOO much nastiness. Mebbe keep it and advance it a couple degrees?
Alternatives I'm kicking around:
Comp 270S 270 270 224 224 .540 .540 110° .022 .022; 1800-5800 (they say "mild rough idle", but how mild is it?)
Howards 252342-10 - 265 265 230 230 .560 .560 110 106 .022 .022; 1800-5800
Lunati 30330511 .569"/.580" 238/248 272/282 112/106 .022"/.022"; 2000-6400
Reason for the dithering? I have another custom pickup, an '83 F150 stepside shortbed, with a super-trick 347 that has a pretty nasty Crower hydraulic roller (specs are only 222/226; .540/.555; 108, but it idles like a funny car - so much for thinking we can look at cam numbers and know how it'll act..), and, while it certainly turns heads, it's a bit too much, so I'm thinking I should go a trifle more conservative this time...
Thanks!!
