Mostly street engine. 11.5 400 stroked to 406" dynoed @ 610HP with 498 torque. Victor intake, Edelbrock heads, Bullet cam
Anything other info needed?

What carb did they dyno it with?

Don't know cause this was the 2011 Amsoil engine 3rd placer and difficult getting strait answers. It was built for dyno but I plan on 90% street use. Yes I know its not built for street but the price was in my budget.
BTW it also has the Harlan/Sharpe 1.6 rockers.

How many cubes? 406" or 496"

Its a 406" (4.375 bore 9.98 deck height) steel 383 crank (3.375 stroke 2.200 journals) ICON pistons (.033 over 1.480 comp height)
Isn't that Dominator a bit big for the street?

I put a Mallory HyFire VI AL ignition box, 32 series billet, magnetic p/u distributor and recommended coil on my race car many years ago and it's worked great. Only a little trouble with one of the connectors. I haven't messed with it besides changing cap, rotor & Accel 8.8 plug wires periodically. This is their low deck BB version at Summit:

Mallory 32 series distributor for low deck Mopar BB.


As for carbs, I only know how to work on Holley's and their Ultra series work well for me, at the track at least. Staying just a little on the conservative side with CFM could help drivability & tunability.

OK any opinions on this Holley 950 CFM with mechanical secondaries?

The motor came with the MSD 8545 Billet distributor and will need a box and harness, any ideas?
Appreciate all the help.

Never worked w/that particular one but again, there`s still some small tweeks that yield big results..........
