We are proud to announce the release our our new product line:
Archangel
"Sending Demons, Serpents and Hellish Felines back to whence they came"

This is a product line of Cylinder Heads, Camshafts and Engines
The Idea of this product line is to provide Punishing Horse Power and Torque while Retaining Production like Longevity with practically maintenance free Service.
We do this by Add of Hydraulic Camshafts (no high maintenance solid roller camshafts here), Non Adjustable Roller Rockers and other important Items like 45 degree Intake and Exhaust Seats (vs other competitors longevity sacrificing 50 degree exhaust seats).

Archangel Line uses only the Finest Components in conjunction with some of the finest machine work found anywhere in the Industry!
Archangel is a Higher Standard of Excellence

We have 3 Long Block Offerings in our Archangel Line:
434ci "Sleeved Angel"
434ci "Boosted Angel"
440ci "LS7 Angel"

Without Further Ado we present the first of our Archangel line offerings! Our 434ci 700HP " Sleeved Angel"
Exact Numbers as Tested with Single Plane intake and Holley Dominator Carb 693hp/585tq (We expect to see another 15-30hp with our Ported LS7 MSD intake & TB combo that we will be running on this particular build):

Is it more stroke and smaller slugs vs the punched out 434 (4.155/4.00).
Is 4.00 the stock LS7 stroke or 4.125 ?

Should be interesting.
