cam and intake selection

[black71]

Hey i just picked up my motor and need to get a cam and intake... its a 70 440, 10.2:1, ported 906's w/ 2.14's & 1.81's.... i intend on street/strip use....also what you suggest for carbueration

[black71]

i was told that a 484 would do well for street strip...

I would also look at a Holley or Proform 850CFM carb. It would be your choice if you want a choke or not.

With 10.2 to 1 with iron heads I would run a little higher duration cam than the 284/484 mopar cam and more lift to help out the porting .... what piston are in there 

[71chally416]

The DC 509 is a good stick for dual purpose.  The best hydraulic I ever had in a BB was the old Cam Dynamics .525 lift. That is, if you think high 10's @124 in a steel RR body is good for a hyd cam that's totally EZ on the valvetrain. Crane bought them out and they can still make that grind if you ask for it. Comp attempted to copy it with their "Magnum" grind but they weren't the same. Attempted imitation is flattery, no?

Lots of Intakes work good on big blocks and there isn't really a whole lot of difference with the single planes. If you want brute TQ you can even use the old design ED Torker that you can pick up for dirt. Might not make the most HP but it will make the most TQ.  The old TM is a decent intake too. That and a 850 Holley and some good headers will give you a body twisting stoplight to stoplight TQ monster that needs minimal maintenance and looks old school.

right on thanks for the help.......and stroker its got factory pistons

I'd go Crane's H302-2 hydraulic and an RPM, with an 800 4150series Holley, or 770 Street avenger VS. Easy, simple, but powerful. Another good choice is the Comp Magnum 292. I think the MP 292 is too much, and the 484 just isnt my favorite because of MP's quality control.

do you want a soild or hyd cam ,
 either way I would be looking at the more modern Engle & Lunati VooDoo grinds , you can get equal to small roller profiles using solid lifters & 1.6 rockers with minimal duration to keep up vacuum for power brakes & drivability

[71chally416]

I have such a setup on mine. Small solid cam with 1.6 rockers.  I don't know if I'd recommend that to someone with limited knowledge though. I've run plenty of Mopes with cams and stock rocker gear. If you break one (I never did, for whatever reason) they're cheap to replace. With adjustable rockers you have alot more expense, many parts that need to be fitted and of course maintenance. And not everybody likes the sewing machine tapping noise from the lifters.

That being said, a solid cam will always outperform a hydraulic. How much do you want to spend, how fast do you want to go and how often do you want to work on the valvetrain? 

[nivvy]

He has stock pistons so lift will be in consideration... 

[71chally416]

I have no such knowledge of the newer hydraulic grinds, but I'm sure they work great. Maybe a call to them would clarify what works with stock clearances?

[Chryco Psycho]

most pistons will take .525 lift unless the heads or block are severly decked

[black71]

I was plannain on runnin hydraulic and i do have power brakes.... have you heard anything about 440source's roller rockers, had a buddy buy a set but he hasn't put them on yet. As for maintenance this aint gonna be a daily driver so as long as i can learn to do what needs to be done a spring/fall tune up or what not wouldn't bother me. Thanks again for your help guys
 

[nivvy]

I really think the only thing right now 440source gets bashed for is there heads.... I had 2 sets off 440 source rockers with no issue...   

some people dont like needle bearings but i do.... 

[black71]

right on... i'll have to get me some lol as long as they aint the purple ones  even though ya can't see them....so if a person were to run a big cam with power brakes, do the vacuum canisters/tanks that companies like summit/jegs really work?
