Magnum 408, EQ heads with 2.02 intakes,flow is 272 cfm at .600. Cam is a Comp MuthrThumper,hyd roller 235/249/107 in at 105, Airgap dual plane, Quick fuel 850 Q carb, 10.1/1 compression, .039 quench, 17/8 dyno headers to start, will tune then switch to TTI 1 5/8 to 1 3/4 with 18 inch x 3 collectors. What do you think it will make?

my guess 530hp/500tq.

488 hp

479

480

My 410 just put down 401 rwhp. Indy 360-1 heads but they only flow 270@500 & 287@600. Comp cams 236/242@50.compression is supposed to be 11.3:1 runs 94 Oct pump, TTI w2 1 7/8 headers, straight thru mufflers from magnaflow. Hutch 727 trans, probably too big of steel driveshaft I'll change to alum later, and runs thru a strange engineering ford 9 inch 35 spline axles with a spool and 390 gears. 275/65 et radias on weld 15x10 wheels. Qft 750 carb 1 inch spacer.

I was hoping for Alot more..but it is what it is. Heads down flow enough and the cam chosen was too small.

500+hp...............

I'm guessing 419.8
Oh wait...It's that dyno? 485

My bad it's this Dyno. 520

Building an EFI 408 as we speak. Zero deck, RHS 2.02 heads, 10.7 cr, 236/242 cam @ 108 lsa, single plane intake, Scat rotating assembly. My builder says it should do 500 hp/525 tq. So that's my guess to the OP. Film @ 11:00

Over 400 and under 651.

"Bob, I bet $1" seriously I guess 490hp

My Magnum 408 that has 2.02 R/T Heads, .242/ .249 @ .050 .600 lift Ultradyne cam,10.3 to 1 comp. Air Gap intake, HP 750 carb. 727 with a 4600 converter made 420 rwhp and has been a best of 11.09 @ 120 mph @ 3520 lbs. Its mild enough to drive and Im pretty happy with it.

Greg my guess is .....enough to make the other Dart fun to drive

Greg, what is it going in?
If a 63/66 dart, those tti step headers were a stinker to get in. Torsion bars, everything has to come out. And the oil filter adapter bolt has to be machined smaller. Passenger header has to come off to get that bolt tight. Real stinkers, but once installed...... nice

1965 dart, but I am using a coilover setup, no torsion bars. I checked the fit on the engine stand, and no problems once I ground off one middle motor mount. Maybe they moved a tube for the adapter?
This Dart has no heater, radio, etc, light weight buckets, Wilwood brakes, and rack and pinion/coilover conversion. 904 trans, 8.8 rear with Ford disc brakes. Any guesses on curb weight?

477hp

Without the DA, numbers mean nothing.

The torsion bars go right through the tubes. Good you have a rack and coilovers.

495 HP / 505 TQ?

Fearless Prediction:

At standard temp and atmospheric pressure my guess-top dyno says 554hp.
