World's First Blown 440 Small Block Mopar on E-85 and built by Muscle Motors (MI)
To my knowledge this is the world's first 671 supercharged 440 CI small
block Mopar that exceeded 1,000 HP with Edelbrock heads (ported and
polished) and "old school" custom Offy manifold. This was designed by me
but built by Muscle Motors in Michigan. The goal was 800 HP but the engine
Dyno'd at 1,020!!!!
This is going into my pro-street 1971 Dodge Demon. I have the Dyno sheet but Muscle motors
didn't show it on the video nor did they put in their name...need
marketing help in my opinion.
1973 Charger 318 390 Stroker on the dyno for a quick run
318 to 390 cubic Inch Stroker Specs:
ICON Forged Flattop pistons
Forged H beam Rods
Comp Cams Thumpr Cam
Heavily Ported 340 T/A Heads
1.5 Harland Sharp Offset roller rockers
Edelbrock Performer Airgap manifold
Holley 850 Avenger Carb
Headers with 3" Custom dual Exhaust
MSD DIstributor, Coil, and Ignition Box
TCI StreetFighter 904
8-1/4 LSD rear with 4.10 gears
The engine is running high 10's low 11's compression ratio and therfore
decided to run a blend of race fuel with an octane rating near 100. After
the Dyno run I
realized that the cam is doing nothing to help the engine make power and it
was evident in the numbers. Don't get me wrong it sounds great but its not
much in the power department, but thats the cams design I guess. The car
made 301 RWHP and 331 FT LBS of Torque.
We changed the carb to a 650 double pumper and were expecting better
results since the 850 is quite large for the engine but to no avail. The
carb change only produced 2 more rwhp and 1 more ft lbs of torque. Not
worth the expense of changing it especially for what ill be using it for.
I will be changing the manifold to a single plane and the cam will be
changed for something more aggresive like comp cams XR292HR-10. Hopefully
this will get a little more power out of the sucker.
Thanks for watching

Mopar R3 small block engine dyno
Big congrats to Jim aka HP Indy. This is his engine Dyno from May 9th at Aurora
Automotive. His R3 block is bored/stroked to 454ci & has Indy heads/intake
cnc ported/matched. This is an efi motor so should pick up about 30-40
hp/trq with the Accell 1350cfm throttle body, no spacer & the custom hdrs
instead of what was run on the Dyno
