Need some help picking a cam for a low budget build. .040 over 440, Keith Black pistons, 6 pack rods. 10 to 1 compression. Street Dominator Intake, 800 Holley Double Pumper, 346 heads that are stock except being freshened. 2 inch headers. Car should weigh around 3800 lbs. I have a 9.5 inch converter that should flash close to 4 thousand RPMs. 3.55 or 4.10 gear. Im figuring the headers are probably a little big, but that is all I have at the moment. Due to a shortage of funds, Im stuck with an off the shelf grind. Looking for recommendations for both a solid and a hydraulic. If anybody has built a similar motor, ET, MPH and cam used would be great also!!! BTW, Im not interested in the VooDoo grinds, anything else is fine. Long story.

I run a voodoo cam, no problems. I would have suggested a voodoo 60304 would fit the bill nicely.

Since you said budget build, i'm guessing you may be using the stock rockers. If so, i've had good luck with the old Comp 292 Magnum hyd. .030 440 8.5 comp, 906s pocket ported when i was 20yo and didn't know what i was doing(still don't), Torker,750dp, 10 in GER stalled about 3800, 3.23s, 28 x9 slicks, 68 Satellite street car all steel except for 6 pak hood. 12.35 at 106, 1.69 60 ft. Cam has been in for about 25 years and hasn't gone flat yet in spite of me not always changing the oil as often as i should. Car sometimes sits for months and then might be driven almost every day for a while.

Ive actually got some 1.6 rockers.
What RPM do you shift that cam?
Thanks

Narrow down to solid or hydraulic first?
Lets say a solid.
Looks like the Comp 292 should work if I go with a hyd.
There are way better cams now then the old cc292. A buddy of mine built a very similar deal last year, had an old comp 280 (230@50) and went to the comp 284xe and gained around a half second. This was in a fully stock body '68 Bee, ended up going 11.6X .
I have had good luck with the.528 mp solid too, but there are better grinds now worth investigating.

Not sure on "way better" part......I laugh everytime a new grind is the shiznit, and the old stuff is junk. My junk runs decent (11.30s)with pretty old lobes (Comp TL lobes).....Thinkin about having Dwayne grind me a cam with the super duper new stuff for a comparison.

Well lets see... the XE284 grind has 10 more degrees on the intake side than the 280, 16 more on the exhaust..., not to mention the extra .25 ish more of lift. The XE grind has 13 more degrees at .200 than the 280. So yeah, it should be quicker. I dont think that is a good comparison.
The XE274 would be a better comparison. 3 degrees more at .200 than the 280. Same intake duration at .050.
The XE284 and 292Mag would be a much better comparison, for the larger grinds. I'll throw it out that in a heavy car the 292 takes the XE284......
Im not a fan of split duration cams, and after talking at length with Dwayne, I understand why.

All I was trying to get at is don't buy a sh!++% old cam. I subscribe to the theory that there is no such thing as too big of a cam/conv/gear. Of course this is the wrong forum for that, but I must explain where I come from.
I agree on the cam/conv/gear thing, but not that the 292 is a sh$$$ old cam. Ive known forphorty for a long time and his stuff runs hard...with hardly anything. Ask the all knowers if his stuff should run 12.30s with... gasp....3.23s...

The only reason I would disagree with that is there are better cams now. The lift on that is .501(?)...And with the bending and deflection of stuff, its under 500 lift. Don't get me wrong, I've seen those cams work too.

A lot of guys optimize those MP cams to run better times with the rest of the combo on the engine. It's a hit or miss game, what could be the cam holding power back could actually be tuning problems, wrong intake, exhaust restrictions, too heavy car for combo, etc. or visa-versa. EVERYTHING has to work together to produce good power!! And yes, not everybody wants to run an MP cam, there ARE many other choices.
