If Mopar were to build something similar, what do you guys think it would look like?
Indy and Trick Flow heads might look out of place, even if I were to have the ends milled to get rid of the logo. Edelbrocks look closer to the MP head, but they'd have to be ported, adding to the cost.

After a lot of consideration given to what the car was supposed to be in the first place and a few non-negotiables, this is what I'm starting with:

BMP block, 4.500" x 4.250" (540)
Lunati solid FT; 259 / 267 @.050", .586 /.606; 110LC; in @106*
EDM lifters
A set of really cool valve covers
440 Source "Super Stock" aluminum alternator brackets
Hughes stainless valley tray
CNC Stealth heads, opened to MW. >> If I want/need more power later, this is an easy change.
Mod Man w dual 750's (I have the CID to make it work)
More money in polished stainless fasteners than I care to admit. It's not a race car. It's a street ca
r, and I like bling.



Nope...lol not a racer car. I have a few of those too. laugh

I also have a set of those bitchin blue anodized DC valve covers. My contention with placing them into service is the lack of a baffle. I had considered many different methods of attaching a baffle and more or less settled on JB Weld.

I am curious what your thoughts are there.

Also, will you being running this thing on a dyno? It will be interesting to see where it peaks hp/tq wise. With that tiny cam I assume it will peak well below 5500rpm @540" ?

I am betting on peak torque around 4800, hp about 6400. It will sound knarly, but pull like a frieght train!


I am planning on a dyno session, but it will be a while before this thing is put together. Meanwhile, I'll attempt to make some progress on the car itself.
The cam is listed on Lunati's website with a power range of 3000-7200 based on a 440. I think Greg is pretty close on the performance in the bigger engine. Something that is fun from 2500-6500ish is what I'm after.
This profile was picked because I didn't want to run more than .600" lift, and I felt the duration was about where it needed to be for how it would be used 90% of the time. That the lobe design was spec'd by UDHarold is a bonus.
