DD2k = Desktop Dyno 2000. Basically it's a computer program that predicts the hp and torque of an engine.

On the heads, if you have the money definately go with the Edelbrock aluminum heads. Stock they flow as good as or possibly a little better than ported stock iron heads, not to mention porting heads is a major PITA. The edelbrocks can also be ported out quite a bit. Heads are where you really get your hp. I think the perfect set of heads for a 390 are the Keith Craft Stage 2 Edelbrocks, listed about halfway down the page. Of course they cost $3000.

Of course if you're going to do that, you may as well go with the roller cam, since this and those heads work really well together. With the above mentioned heads and the 521 roller cam, you're making 170hp more than the standard ported stock heads and 941 cam combo.

Yes, you can mix and match valvetrain components to a certain extent. However, you have to make sure you know exactly what you need.

 

I just got a Dynosim program with a cam data that has 3,760 cam profiles to play with. This is a "WOW" program. Still learning to use. Total cost at the door was $202. Carl.......o&o>............

 

let's see, 3760 Cam profiles.


that's about 2000 SBC, 1100 BBC, 200 SBF, 200 BBF, 60 Mopar, 98 misc and 2 FE cams :-)

 

What about intake??? What line should I go for what I mentoned previously??? basicly, which carb and manifold would work best??

 

I'd go with the Edelbrock Performer RPM in all cases. The only catch is, that if you use stock heads you have to open up the intake ports in the heads to match the intake manifold.

 

gtex, i must correct you, there are 142 cams listed just for the FE. The other 3,618 different cam profiles can be used also. If a Toyota cam, Dodge, Chebby or Olds cam profile works best for your engine combination use the specs and have a custom cam ground on a FE blank. Dodge cam in a FE, no fit, Dodge spec on a FE blank why not? Had to inform. Carl.....o&o>......

 

gtex, sorry but the breakdown you posted was 3,660 cams, were did you put the last 100 cams? Had to ask, is this that new "EMRON TEXAS MATH"?
Carl......o&o>.......

 

So if I used the heads I've mentioned, then it'd be a decent combonation?

are you talking the Stage 2s and roller cam???

What would be too big in the way of carburators?? I've got a 650 cfm Edelbrock four barrel.... or is larger needed???

Where can a person pick up a DD2k???

 

Well, I didn't post it for nothing!

I think a 750cfm carb would be about perfect for it. 650cfm would stil work, but you'd start losing top end hp.

If they sell it on this site, I'd go there first. Otherwise, do an MSN search for "Desktop Dyno." You'll get zillions....

 

Thanks, I just thought I'd make sure,

Do you have any recomendations for carbs in the way of makers???

Oh and off topic, I like your truck Rusty, looks great even w/o paint, and I like the old aluminum rims, I've got a pair of those but in chrome.

 

I was actually going for 3660....guess I'm getting lysdexic in my old age :-) Good to see they had a few FE grinds in there...

 

gtex, your still in my will. Carl.....o&o>..........

 

Thanks 1970custom. The paint will be coming after the engine goes in. I didn't take any pictures of the interior; there's a reason for that. The aluminum rims came with the truck. I wish I knew where to get them today.

I've heard of some problems with off-brand carb makers. I'd just stick with what works, and that's Holley.

 

What intake manifold would you recomend next to the Edelbrock performer???
I was looking through the Summit catalog and came across air gaps, dual and single plains, stealth, low, medium and high rise manifolds. Just wanting to know.

I'm guessing you'll sugest the Edelbrok but maybe not.

Also, what style of headers should I use?? Long or shorty.

And finally what torque #s would I expect from this motor if it were built for a reliable street/strip motor???

Thanks
Eric

 

Blue thunder is a nice alternative to the Edelbrocks. A little more price wise but not that much. Holman Moody still sells manifolds and is making the OEM grind cams from the 60's if you like the nostalga items. They are on the H/M website or the 04 FMS catalog. Carls ford parts and DSC are both blue thunder dealers and Carls has some pics and prices on his site. www.carlsfordparts.com I really like the Edelbrock Victor and Keith Craft is having a special on them for $425. Cheapest I've seen for the Victor has been a tick under $500. Pretty much a race item though as it's starts making power at 3-4000 rpms but know a few guys running them on street cars. G.
