Putting together a new engine combo.
4.15 stroke,6.76 rod,4.32 bore 487 cu.in.
Heads flow 330 cfm at .700
6bbl. carbs. All three intakes to experiment with. Edelbrock,Weiand SS.and STR.
Compression 11.18.
Automatic 727 NO brake.
Two converters in hand 8"ATI 5,500
Dynamic 9" 5,000.
Gears 4.88 or 4.56
32.5" tire,,,,ladder bars-coil overs.
3,000lbs w/driver

Have a .590 best et. 9.87 3.75 stroke 440.

also have 620.MP. cam. I have never tried it.
Roller isn`t a good value for me,would rather go with a solid for now.
Maybe a couple years down the road.
So what cam is a good blend of performance and reasonable durability?

Id throw the 620 away from the dyno tests ive seen from it. The .620 has to tight a lobe center for a stroker like that. Id probably pick a hughes 268/272 630, lift on a 108 cl or their 272/276 650 lift on a 108 cl

Or you could go with a comp grind SQ lobe 7265/7265 witch is 271 @ .050 with 603 lift on whatever cl you want, for me a 108to110 or you could pick any other cam around the same perimeter IMO

What heads?
Std port window?
1.5 or 1.6 rockers?

Stage 6
STD.port window.
I have 1.5 and 1.6 rockers

Stroker usually gets narrower LSA: larger displacement (more inches, same breathing) + slower piston motion ABDC captures more charge at the same point of crank rotation.

Is this a drag race only build or a street and strip build?
If drag race only I would install the .620 and advance it so it is in from 3 to 6 degrees advanced on the ILC Big motors love big camshafts
Who ground that .620 cam and what LSA is it ground on ?

Race only.
It's an old,probably 15 years old Mopar Performance 324/620 solid.
I think the LSA is 106 not sure?

Put that rascal in there and degree it and check the valve to piston clearances and use it if it fits

Ok thanks.
This is my first stroker engine.
37 years of 440's in the Cuda .

Not trying to rotate the earth, just want it earn it's keep.

I built a pump gas low deck stroker six pack motor years ago with a Eddy low deck six pack intake, that motor made peak torque at 4500 RPM and peak HP at 5500 RPM just like I had heard before that every six pack motor did
At the track that stupid motor liked to be shifted above 7000 RPM to make it go as fast as it would
If I was you I would start out with the stock type Eddy six pack intake first and flog that combination on jetting, valve lash, timing and shift points first and then go from there
I had one of the Weiand SS two piece cross ram six pack intakes that I never used as I didn't build a pump gas 440 block stroker motor before selling my Duster with the low deck pump gas motor in it
I was really happy with the way that old low deck stroker six pack motor ran Best ET was 9.993 at 134.8 MPH through the full three inch exhaust system on Oregon pump swill with the air cleaner on using a set of Indy SR heads with M.W. ports and a Indy 400-3 single plane intake and a 1050 CFM Holley Dominator, that car weighed 3450 Lbs. with me in it with a full tank of fuel
Made a whole bunch of "real" racers mad at me with that car

I would do it!

The Edelbrock will be the 1st intake for sure. Been racing it since 1983,pretty much have scienced out.
Ran the SS manifold a few times, ran the same as the Edelbrock.
Might be different with more cubes and stroke.
Lots of things to tinker with.

Curious how it works out if you try it. I considered that cam but went with something else. I didn't have one on the shelf though . I like the fact that it seems to have gentle lobes, 324 advertised duration/.620 lift.

It is on a 106 LSA I saw a direct dyno comparison between the Mp .590 and the Mp .620 on a 440 around the same comp as your stroker. The .620 made Less power then the .590 until about 6200 RPM, even with that the .620 only made about 5hp more then the .590 but only for a few hundred rpm. from 6200 RPM and below the .590 was the clear winner.

Your stroker isn't That big and your comp is fairly low for a cam that size. Go ahead and try it since you have it, but it will be a dog with you combo IMO I still have the dyno sheets somewhere, if I can find them , I will post them for you. you wont see me Ever using that cam.

I just notice that your racing a stick shift car last night
I use to race a stick shift 1970 hemi Cuda (not a real hemi car, dang it ) in NHRA stock class that required a LOT of maintenance
You control the rpm range, correct? So that cam may be the hot ticket for you

You may turn out to be correct, I would`nt buy one now with all the cheaper better proven cams out there.
Came in a short block I bought in 2000.
However pretty much everything on the car is not what others would have chosen either.
6bbl-- never get it out of the 12`s
Stage 6 heads --junk 19 years without even a valve job.
4speed-- It`ll be a half second slower and you will never be consistent, Picked up 2 tenths and won the Mopar nationals twice in 4 attempts,semi finals the other 2 times.

So it`ll either run 10`-O`s or 9.50`s LOL

Jerico ain`t going back in with the new combo. Putting the auto back in,,,at least for now.
Would love to step up to a Liberty or G-Force down the road. See how long my back lets me play.......

awesome!

For that CI and Standard port window head I have run the Comp 290/650 solid and the Crane 280/670 roller. Both were within a 10th of each other, however the roller was more consistent and ran much better in the heat.

Have the 650 on the shelf if you want to give it a try.

Look forward to seeing the Cuda back in action!

Hi Dennis take Mike up on his offer you will like the comp 650. As for the Hughes cam, specifically the 268/272. My car really like that cam. My cuda ran a best of 10.18 with it at 3450 lbs. That was shifting at 6300. At your weight you should be well into the 9's. However I wouldn't run it again the down side with that Hughes cam was it was hard on springs. They were shot after 150 runs. I ran the springs that Hughes told me to run, maybe he had a bad batch but the ramps on his cams were aggressive for a mechanical and just beat the springs to death.
