We are getting ready to build a 440 source 438 kit with stealth heads for a 1969 roadrunner with a four speed, 3.55 posi and a factory air grabbe, our questions are, what intake carb combo will work with the factory air grabber set up, what pistons, flat tops or dished should we run and which non comp camshaft would be a good selection with this combination ?? What exhaust manifolds/headers What heads? What kind of HP/TQ expectations do you have? Power brakes? What type of idle quality are you ok with?

With a 383 air cleaner base you can only use a stock height intake and a stock height carb, no spacers or adapters allowed. With a 440 air cleaner base you can use an intake that is maybe an 1" taller?
running up my post count some more .

Here's my 2-cents.
1. JohnRR is exactly correct. You need to run a stock height intake manifold. I'm not positive which ones are stock height. The 440-style (GTX) air cleaner gives you about 1" more clearance for a 1" taller intake vs. stock. Airgrabbers are SUPER tight for hood clearance.
2. Tempest idea of a drop base is good except it is not compatible with a 69 airgrabber air cleaner....unless you cut up an airgrabber base and graft it in. (69's are big oval air cleaners, even the 4bbl ones).
3. Your cam sound reasonable...."maybe" one step larger, but for good drivability it sounds about right. You will get 100 opinions on the cam. Some people on here are much more knowledgeable than I am on cams.
4. I would suggest a Holley 750 vacuum secondary (WAY better gas mileage), but for a track car, a double pumper with the 4spd would be good. You might look at some of the performance Holley-style carburetors too if you plan to race.

Personally I have never like comp Cams as I see more of the go flat hands down than all others combined. Comp Cams has been the major player in the after market cam business for a lot of years, when you sell the most of any products you will have at least as many failures as every one else but who remembers the failures of the other companies that couldn't keep up with the leader in volume A lot of cam failures are the engine assemblers fault regardless of the brand due to not getting the motor started right away and breaking in the cam and lifters properly

I'm curious, Why not use a 400 block?

Just got mine on the street for its initial test after a year
Numbers Matching 383 Magnum / 440 Source 432 Stroker
Kit came with Icon Pistons - 10.3 Comp
Had my engine builder balance the crank
440 Source Billet steel main caps - Line bored
Edelbrock E Street Heads 75cc
Factory HP Exhaust Manifolds
Howards Cams Billet 9 way adjustable Timing gears/Chain
Comp Cams XE 275HL - After degree installed straight up or dot to dot
Brand new Weiand Dual Plane Intake
Factory 1971 440 HP Carter AVS 750cfm that I worked with Edelbrock Jets/Metering Rods / Springs and Covers
Numbers Auto Trans Rebuilt running a new Turbo Action Street Valve Body
Factory 3:91 Sure Grip
Right now running about 18 degrees initial with 18 degrees mechanical 36 Total
Starts and idle is awesome even cold with no choke
Only thing at times with that cam and lifters sounds like a overpowered sewing machine when cold , quites up better when hot
Valvoline VR1 Racing Oil Silver Bottle 10w30
Hot idle 25psi Hot cruise 75 psi oil pressure
Off idle 700 Rpms I can destroy/burn the 275/15" Cooper Tires from Green Bay to Chicago if I wanted
Now I have a real dilemma , TRACTION at stop lights
I wanted TORQUE off idle to say around 5600 5800 rpms for street use only
Will drive it for awhile before deciding on possibly a new carb and maybe maybe headers
Weather sucks in WI , snow tonight
