2 weeks after engine masters shoot out we put the engine in my buddys street car (nice 1972 dart).
3018lbs with him in car. The engine in roller cam 394 CI 10.9to1 CR small block mopar.
Old engine was 13.5to1 W5 416 I fixed up last year. best pass for old engine was.
1.37 60'
6.35 1/8 mi at 108 MPH
9.94 1/4 mi at 135 MPH
I would like to see what you guys think the pump gas engine ran today we did run it with and without exhaust today....

Can you give us the run down on what the new engine made?

628 HP at engine masters
534 TQ at engine masters
here is the link to the build

10.28 @ 129.5

9.99 at 131mph...please don't make us wait till tomorrow...

What did it make on Riders dyno?


Steve

Not much time for you to guess but I hate that game LOL I made one pass in it today and I can tell you this is one mean street / pump gas engine the car will not hook at all now look at the 60' time...... car has lots more in it yet hope to go to fast track next weekend if weather holds out. oh its car 9980

GEEZ! That thing is flat out flying! 138mph! Nicely done

-Kenny

yes good MPH that slip was open headers I dont have slip to scan in with the mufflers but the best pass with the exhaust was 9.97 at 137.30

very well done ,awesome street car

What was the head you used? from the pictures on the other thread it looks like a 360-2....

Are you going to try it with a different carb next weekend? Bring it on down to MIR on Saturday, you will be sure to hook there!

That's funny how it ran the same ET number as the car number. Next time I hit the track I'm gonna request that same car number so I can run a 9 second pass!

That's flying for a mild small block.

Wow it is pulling hard, was it spinning the tires. Congrats.

what converter stall , Tyre size,gearing it all works well together

Brett called me from the track so, chassis and track conditions
are based on recollection.

I believe the Dart has 28" tire and 4.10 gear. Converter is a
3500 stall nitrous unit built for the previous engine so, hardly
optimum for a N/A all-out drag car.

Track was crap. 900 ft. of actual elevation with D.A. in the
1200-1500 ft. range most of the day.

Engine was built on a "do or die" basis. Components were selected
and used, Period. One camshaft, heads and intake ported and bolted
on. 18 hits on Rider's dyno before the competition. That's it.

The cam was a little too big for the competition but, big enough
to pull double-duty in a bracket car. Drop-in roller lifters
were supplied by Brian Hafliger @ IMM Engines and they performed
flawlessly. Mid-range torque is absolutely wicked for a 10.9:1
street engine on pump swill. IIRC, it made 457 ft/lbs @ 3000 RPM.
138 MPH @ over 3000 lbs. is a testiment to it's overall potential.

Brett labored over the cylinder head and intake porting intently,
while I could only supply some of the hard parts I had on hand.
Billet 3.792" crank I sent to ShaftTech to cut to SBC 2.100"
rods and re-heat treated. Jim Mikel @ Performance Technology did
the beautiful "no-hole" balance on the crank. Callies Compstar
6.250" SBC rods, Calico coated Clevites and custom JE domed
pistons round out the rotating assembly.

INDY 360-2 CNC 230cc cylinder heads were reused from last year,
with some radical changes in valve job and port work. (Hi 330's)
Ferrea 5/16" stem valves in 2.08" x 1.60" size.

INDY 360-3R obviously got several hours of attention, as the plenum
was opened to 4500 flange while employing a semi-permanent, cut-down,
tapered Wilson spacer, along with extensive porting in the runners.

A Pro Systems custom 1050 Dominator from last year was again reused.
It proved to be a good match with air/fuel ratios in the mid 12s
throughout the entire pull.

1 7/8" Sprint car headers with Magnaflow mufflers were used on the dyno.

Weber belt-drive and antiquated Milodon S/S pan were reused from last year's 344" as well.

Updated INDY 360-2

JE/Compstar package.

Wow... I'm impressed by the results, both on the dyno and the track. /

BTW, I hope you're not using today's ethanol-enhanced pump gas w/ that engine just because it's only 10.9 cr. All that epoxy WILL come out after exposure to the alcohol, just as I found out the hard way earlier this year.

WOW! Thats some insane MPH for that combo. Very impressive. Is your cam selection top secret? Its obvious you guys did some extensive work to the ports and im sure the rest of the heads, but how is that cam profiled if you dont mind me asking?? I know alot of people claim that there is a way to make an engine win a dyno contest and then there is a way to build an engine that gets down the track fastest....well its definitely fast down the track. Im not sure how you guys did in the dyno challenge , but im sure it was good. If not; who cares that thing runs fantastic!!!!

I would not tell the cam specs but, Brett posted them on the original EM post.

It's a roller ground @ Predator

255º/266º @ .050" 108º LSA installed @ 102º
.704"/.704" w/1.65 rocker arms.

Intake lobe is 28º difference @ .020" so, it's pretty snappy.
