myself with all my daily driver trucks I like the Hughes whiplash line of cams flat tappet or roller cams.

I just installed my 5.2 roller whiplash/comp 901-16 springs into my 360 headed 318 added RPM Air-Gap intake/625cfm carter afb/1 5/8" headers 2.5 duels/2.5 in/out magnaflow muffs/727 CRT/TF-2 VB stock HS-TC-non lock up auto trans/3.23 gears.

I did add MrGasket mech advance springs to points dist so advance is all in by 1800rpm set timing full advance @32*

jetted carb 1 stage richer on primary and 3 stage richer on 2ndary

now the old 85 stepside gets to stepping in traffic. idles 500rpm in gear at the line with a slight bump, pulls right off with light throttle in traffic, and is really a nice daily driver.

now my 440 whiplash is another story. it is nasty sounding, very choppy idle and is a beast when getting on it BUT it really does daily drive in traffic rather well.

once I locked the dist mech advance to full advance and dialed the timing to 32*-34* it will idle 25mph 3rd gear through town sounding like a dragster and smooth's right out about 1800rpm and cruz 45-55mph and has a big passing gear

all with a stock MH 440 cam/spring swap and a stock 727 low stall truck TC 2.76 gear 29x15x15 M/Ts the 3.23 are sweet and the 3.91 are even better but the 4000lbs beast will cruz like a big old Chrysler 4-door with those 2.76 down the interstate with unlimited top end. but sounds like a dragster idling around town.. the 3" duels/muffs might have a lot to do about that sound being so nasty.

I vote for the whiplash line of cams. my 0.02$
