Well I guess its a little early to guess dyno numbers, but it should be very close. This engine has all the options including Billet Main Caps. We stuck with our standard H-Beam Manley rods on this engine. Compression is a nice 11.5:1 so that should give away the power adder being used.

So, You're now doing 419's and 426's?

Whats the difference between the 419 and the 426?

Whats the difference between the 419 and the 426?

7 cubic inches.

7 cubic inches.

Why make 2 motors so close together?

7 cubic inches.

Oh snap! Ouch. :D

So Andy, is this going into a Jeep SRT8? What size shot is the owner going with?
.

Thats awesome, cant wait to see the final numbers.

419 just has thicker cylinder walls. I actually recomend that to everyone so that they have the option of rebuilding it later into a 423 and then again into a 426. Once you go 426, you cant really rebuild without extremely thin cylinder walls.

Not a Jeep. An LX. Nitrous will be between 250-500.

You and me both.

The differences are in the stroke and the size of the bore. The 426 would
use a 4.08 crank stroke and 4.08 bore. The 419 would use a 4.05 crank stroke with 4.05 bore. Is that right Andy?

Close.

426 can be made with both strokes.
4.05" stroke x 4.09" bore or 4.08" stroke x 4.08" bore

The 419 is a 4.05" stroke by 4.06" bore. This allows a 4.07" and 4.08" bore later for rebuilds. I have never taken an engine to 4.09"

I know someone who went to 4.10.

A guy on LXF went 4.10 also, doesnt mean its a good idea though :)

NICE! gonna be a beast!

Is it Koolaid injected?
