The MOPAR power myth?

Agreed. And i guess one has to determine what's fast........
Saw a guy that threw a cast iron 906 head 440 in his dart, 727, 8 3/4 3.55 rear pound 10.50's all day. Single 4bbl, solid cam, 9.5 compression. What, a 1500 dollar motor roll'n 10.5's? Pretty cheap to me, and reliable.

Same day a stroked 440 (big cube motor) Duster with 4.11's couldn't get out of 11's.

A lot of times going fast is knowing what you are doing...... just say'n.....

Yeah I used to build Mopars as cheap as possible - tons of stock parts and used speed parts. Only bought new parts when I couldn't find it used or it was a wear item like gaskets/hoses/bearings/etc. They still ran great and stomped a lot of "built" cars. Granted that was before the era of $300 5.3 LS motors and eBay turbos, but I know if I duplicated a couple of my old setups and added some extra nitrous and a controller it would still be somewhat competitive in local events.

If you're buying all new parts, expect it to be expensive - you're the first "sucker" in the equation!
