68 chevelle malibu
327 .40 over
670 holley vac secondaries
hooker headers
hei distributor
cast iron 68 heads gm with 2.02's ported and polished and deshrouding
stock 10 bolt highway gears I assuming, not sure on gearing
th350 trans with a 2000 stall converter
245 60 r 15 front tires
275 70 r15 rear tires

Will this camshaft work for my combination, I would like something with some good low end torque and a nice slight lopey sound, good idle quality with a good vaccum for brake booster for disc brakes.

or what would you guys recommend for this set up???

The cam will work fine for your purposes. The only thing I see wrong is you don`t know the gearing, the rear gears will dictate how your combo performs. If you gave it some 3.50:1 gears It would work nicely.
Make sure you match the valve springs to the cam.
I wouldn`t use this cam, but that`s just me, but it will work for what you want to do.

what would you use double vision if this was your set up?

Even so I don`t like to pick cams for others as I`m conservative, I will say that cams today such as the voodoo and extreme energy grinds are far better than the grinds of old. This cam I found on Lunati`s site in the Voodoo line looks good.

Thanks double vision, this cam does look good for my application. wonder how the idle quality is? and the vaccum for booster? maybe i will call tomorrow and talk with a tech at lunati, thanks again

It should have a fairly choppy idle. I`m sure it should have plenty enough vacuum for power brakes. However, contacting Lunati and asking is a good idea. Just call me DV, it`s easier.

For "Hiway gears" and a 2000 stall find a cam with 208 to 218 @.050 duration.

The cam you are looking at wants a bit of a converter and some gear to work best . Up to a 3000 stall and 4.10's for strong street performance.

For the gears and converter you got you'd be better off with a bit smaller duration cam. Like a Comp dual energy 265DEH-10 or similar.

211in -221ex @.050 .442-.465 110 LSA. Lunati and Howard have similar cams.

You cannot have a rough idle and good vacuum, pick one.

you can use manual brakes or hydro-assist if you don't have enough vacuum. Most engines I build end up requiring that- its no big deal.
