Speedomotive 500" short block, Indy EZ heads 76cc, (I could change these)Comp Cam HYD cam .525 lift,Victor 440 singe plain intake,Holley 770 cfm,TTI 2" headers. This will be in a mostley street driven e-body 4speed 3.91 geared ride. What would u change if u could he'd like to keep pump gas.

The 500" would really wake up with max wedge ports and a bigger cam.The combo you are currently working with would be great for a 440".The 500" needs more intake volume,bigger carb,cam.With a 4 speed you can run a large cam and adjust the power range with the centerline.

I like the Max wedge ports, solid or hyd roller cam, and @ least a 850cfm, We can easily make intake work.

The hydraulic cam you have listed is a horrible choice. I would use Comp Cams XR292R solid roller. It is listed as a street roller grind. Intake with 1.5 rockers .582/254 at .050 Exhaust .588/260. My brother has this cam on his 496 and he drives it all over Michigan. It makes great power for both the street and strip.

If you are going to drive on the Street a ton, I'd keep the port velocity high to make for a nice 4 speed drive at low rpms!

I can tell you the EZ head daily driver 448 in my Road Runner:

3.75 Crank
4.36 bore
EZ-1 W/MW port entrances, SDSS VJ & little hand blending
2D ICH intake
750 4779 DP carb
1 3/4 header
242/246 .580" Hyd roller on 108 LSA in @ 104

It idles @ 680-700 RPM in gear @ 10" vacuum & so far only 2 runs on it, (both 1/8 mile) 92 MPH in the 1/8 @ 3700 race weight (~116MPH 1/4 mile) With 3.23's. 3600' DA Will get some 1/4 mile passes on it this weekend.

500 Inches would make cam act even more tame & add around 60-70 ft lbs of TQ.

So, once you put good set of heads on, it really does'nt take alot to make it run decent. I would use the 2D intake instead of the single plane on a set of EZ's for street use.

BTT for working people.

This will be in a mostley street driven

IMHO stock size ports will be the best. They will keep up till 5,000 + rpm. Cam choice should also dictate a closing intake point no greater than about 45 degrees abdc to put the torque down low where a street stick car needs it.
Another point about the heads. With the stock window size, peak torque can be produced at 4100 rpm, peak hp at 5600 rpm if parts are chosen properly. Obviously, you can move this around a tad, but that is the "sweet spot" for a stock port window 500 cube deal. Go to a Max wedge port, and it will move up 1000 rpm. I have been there and done that. Car didn't go faster till I raised the rpm a bunch from where I ran it with the stock ported cast iron heads.
Edit; did the math on RYANJs cam. It has an intake close of 45 degrees!

First question Id ask is whats the comp. If the pistons are 0 Deck your looking at around 12.4 comp with those 76cc heads. That wont be compatible with Pump gas. mike

you got kind of a mish-mosh there but the EZ's can be opened to MW pretty easily,(later if you prefer) not the best choice for standard "906" port window power but will be good enough for what you're doing with a sharp VJ and try to wake up your .200-400 lift numbers a tad. If it were me I'd go with the old MW -1 (Regular Indy with the better exhaust port) and an Indy 440-2D, (A VERY UNDER-RATED INTAKE IMHO) I've built 8 500" B & RB motors and it's really the best AFFORDABLE combo for a dual purpose mid geared car. You'll want a D-DISH for about a 10.5 TO 10.8:1 STATIC CR with zero deck and .037 quench with a closed chamber. You can run more with the right build but this will get you close enough to optimum power without upset....provided you run a very good cooling system. there's a lot more power in the 2-D with some judicious porting, with a hydraulic cam you're not going to be spinning it high enough where a single plane is going to pay you back with more top end power to offeet the throttle response and upper bottom on up shove in the back.

Carb is too small...., I'd go 850 minimum and a 950 or 1000HP 4150 won't be too big.

my on the port size, I agree with ryan on the MW...to a point.....if you've got about 3800 stall or a 4 speed than it's a great/best way to go, with an Auto with less gear and tigher stall the best port window I've found is about 3.25" which is roughly 2.375" x 1.375" with an equivalently ported Street dominator intake that flows about 310-315 cfm, I'd be real tempted to get a set of Jeff's Modern Eddies for a typical 10:1 3.55 geared 500 motor. The port window I mentioned takes some work (you need to make your own gaskets cause the valley pan ports won't work that big.

Comp 305 is a very decent default cam for a street 500, no issues with it, if you're going to stay with a Hydraulic you could do a lot worse. I'd look at a Bullet/UD in the mid 255 range 108 split, ~104 ICL, but with about .040-.050 more lift. You can sactually put the cam in straight up with a standard port but with the bigger head the extra 4 degrees advance will make it a bit more responsive all around.

2" by 3 1/2" header

Are you hard sold on the Speed o motive? Not sure what bottom end components they use, I prefer to Cherry pick the parts.

On a 4 speed RB I think I'd go for a 7.100 rod for a little less side loading, actually to be honest in a 4 speed car I think I'd just build a 3.90 stroke 470 and have a few hundred more revs up top for the same combo and save the crank $$$ (offset grind vs a new crank) and put the $$$ I saved into the heads. My is a good 470 (especially a low deck) will go toe to toe with an equivalent 4.15 stroke 493, at least the way I like to build them anyway.

here's my latest:

This car has had so many BIG block motors (strokers, blowers and std 440's) in it I should use Clevis pins instead of bolts for the motor mounts! This one's THE ONE for me though, the next motor that goes in this one will be the ornginal 440 as a resto....but I can assure you that ain't gonna be any time soon!!!

Wise, I like your thoughts on port size, seems this combo is very close to the cross over point hence all the different opinions.

I wrote a whole book on this subject.

Greg,

Yeah I guess I'd like to know more about the bottom end....what I was saying about a 470 is that sometimes it's a good trade with a 4 speed to give away a little bottom end (keep you from overpowering the tires) and trade it for the same amount of power a bit higher inthe powerband....but a lot of that depends on the bottom end components and how free revving it is. I've seen a fair number of both heavy and light Bobweights in the 493 (4.15 stroke) range. The 'Old school' 493 4.15" stroke was chosen by Mopar based on being able to use a factory 400 piston with a 440 6.76" LY rod. It's an off the shelf combo and perfect for somebody who just wants a cheap torque mule but it's a bit heavy down below and (with cast slugs) not something you want to rev very high....then again you don't need to. I don't know what the speed-o-motive kit is based on, my preference in the RB is a 4.25" crank with the BBC journals, it's actually an easier build but maybe that's just me.

I'm slowly getting all the parts for the 4 speed to go back in my charger, My die-hard Ford buddy admittedto me this thing revs faster than a Boss 302. To wit I said,,,,,Duhh!!

Ryan,

I think that manifold is a big reason it's as responsive as it is with the MW...If you were to put an indy single on it at 448" with your CR and I'll bet it won't fall out of a tree below about 4000. I'd love to see you tweak on your 440-2D like I did on mine, the lower plenum especially. And I'm just a semi-edmacated hack, I can imagine what it'd do in your hands.

I agree.... after seeing this 2D manifold, though, I can't see why anyone would run anything else unless it is a motor that is going to have a 4000+ converter behind it & alot of cam.

If you're doing a 500" street motor with cam under 250 @ .050" on pump gas, I just can't see running a single plane.

Some guy made snide comment about the dual plane @ the track last week, & I just laughed & said, yeah I'm sure it is'nt hurting anything seeing how I have a Hydraulic cam & don't turn it harder than 6500.

Well good news Indy is upgrading us to MW heads maybe even a intake exchange I'll let u know. Thanks for all of ur opinions. Oh I did just recieve my copy of the BIG BLOCK book.
