So, you remember this little guy here right? http://www.forabodiesonly.com/mopar/...d.php?t=230105

Well its hot off the dyno And Im VERY happy with the results! Here is the basic run down

440 4.350x4.250 = 505
Mahle flat top pistons
PEP 7.100 I beam rods
RPM heads w/2.19-1.81 valves
MRL Stage 3 porting
Victor intake, untouched right out of the box
Custom Solid Roller cam 255/263@.050" .625" lift ***LSA
MRL Performance Pro Sport lifters
Quick Fuel Black Diamond 830 carb w/choke
Melling HV oil pump
7qt oil pan w/ 3/8 pickup
Mallory 42 Series dist and coil
HV mech fuel pump


Power. You want power? How about torque? Do you like to have a torque Monster for the street? Yes and Yes you say? Well here you go!

How about 600+TQ from 3700-5700rpm and 640+TQ from 4000-5150rpm! This engine carries peak torque from 4250-4600rpm! FLAT and I Mean F-L-A-T!

And power, hows 600+hp from 4850rpm on up. This engine hit 500HP at 4000rpm and hit 600hp at 4850rpm!!!!

Now how about the A/F and BSFC. A/F was in the 12.7-12.9 range thru the entire run. BSFC was from .350-.410 the entire run. Waste not Want not! It was run Super efficiently and we were not wasting any fuel. Not to bad for a 10.9 to 1 engine running 93 Octane gas from the local Shell station!

This is a real Street Killer. Idles at 950rpm pulling 11-12inches of vacuum, Fires right up with no issues, just hit the key and fry some tires.


Plus all runs were at a Realistic 180* coolant temp and an Air Cleaner! Nothing Tricky, just a Hard Core Street Killer From MRL Performance, your Mopar Manic that can get it done!


All this for $11,500 complete Carb to Oil Pan, Dynoed and ready to run in your car. This one is heading out west, But I would Love to make YOU one too!

For those of you who are in the know about A/F vs BSFC, It DOES NOT GET ANY BETTER THAN THIS WITH A CARBED BBM. This engine was designed to run as efficiently as possible on the street with this much power. I dare you to find ANYONE who can do better!
