head, cam, and intake combo

[sbh126]

I just pulled a 440 out of my 77 new yorker and I'm now making plans on how to build it up for my duster. I found some cheap aluminum heads on 440source.com for $900 assembled. PN 200-1055. Are these any good or junk? What would be a good cam and intake to match up to these heads? This will be mostly a street car with the occaisional trip to the track.
I need to increase compression but would rater not change pistons. If I put this 80cc head on what will this bump my compression to?
Will the original oil pan and mounts fit in the duster? If not where can I get ones that will? Any help is appreciated.

I would save up for some different heads...maybe eddys..around a 530 to 540 lift cam and a eddy Performer RPM intake...would have to know what pistons you have to comment on the CR...oil pan if center hump should work...motor mount unknown...they would both have to be spool type but I believe you will have to go with Scumachers Creative motor mounts if you are putting it in your small block Duster...

I looked at the Edelbrock 60929 Performer RPM Heads but the flow numbers are about the same and it has a bigger chambere. is there a different set I should be looking at?
How do I figure out what pistons and cr i have?

Theres 2 big block Edelbrock heads. The 440 source heads have a good rep. Both need work OOTB, basic check and re-preping/correcting is very possible and for best performance.

To figure out your compresion ratio, you need to know a few things about the engine. How far down the piston is in the cylinder. (Or if you rebuild it, which I highly recomend you do for a high performance engine since a low compression engine won't "Get It" ) Or simply, where it sits below, above or even (Zero deck) in the cylinder. Head cc amount, gasket bore and thickness, actual bore size. There are on line calc's for this. Also, how to rebuild/HotRod books will have the math to show you and figure out.

If your 440 is a stock 77, it shouldn't be to hard to figure the pistons are OE just by looking at them. Post a picture, chances are somebody will know by site.

This is the biggest question. What combo. While your description is common, it is very vauge. What gear ratio do you want to run? Will you change a converter? Run headers? How fast do you want it to run? Will it be used everyday? Should it be able to?

I have Hensley Racing's BLue printed and ported eddy heads with the indy dual plane and a purple shaft mechanical 242@.050 and .557 lift with 1.6 rockers.

I would recomend the victor jr. intake.

You need to find why what happened to you happened 1st before shooting down the stealth heads.

I would go with the Edlebrock package, with the RPM heads, 800 cfm carb, RPM intake and RPM cam. With 9.5 compression it should make 484 HP at least 500 ft lbs. of torque. Edlebrock test result. I got 10.5 compression, made 500.9 HP at 535 ft lbs. on the dyno.

Any new heads should be checked by a competant performance shop. With the Stealths gasket choice seems to be fairly critical. I havent used them but since day two there were posts on various sites about that. On a '77 440 with no other changes I'd think they will raise the compression to about 8.5:1. Factory assemblies are closer to 7.5:1 than any published specs. Run a small cam, something under 225°@.050, and I'd run the RPM or Street Dominator with either a Holley Street Avenger 670 or an Edelbrock Thunder AVS 800.

I'm not sure what the @ .050 specs are on a stock cam. The advertised was something like 255 and the HP version had a litler bigger cam than that.

225@ .050 is tiny for a big block. also of honorable mention is the advertised and installed centerline and overlap.

The cam in my 440 is a 242@.050 with 60 degrees of overlap and 112 advertised centerline installed at 110 idles really mild. I was almost a little dissapointed how smooth it idled. I initially ran it with a stock convertor, 3:91 gear w 28" rubber.

sounds like the MP .528 cam, broad power band.

 

[roccodart440]

That's the one except I have .557 lift due to the 1:6 ratio rockers. Very broad powerband indeed as the dyno resutls showed.
