Arao
Engineering Inc. is a company that
Truly believes in the saying “MORE
IS BETTER”.
For instance our 32valve B-2 s.b. Chevy
heads were put on a basic 350 cu.in. motor.
This motor consisted of: 10:1
compression, single plane street aluminum intake manifold, standard early
LT1 hydraulic roller cam, 750 cfm. Holley carb. .Which produced
475 horse power @ 6,000 RPM that’s 203horse power more than a stock iron
head, 159 horse power more than a very well known aluminum 2valve (CNC
ported) head . As far as torque is concerned we walked away again. With
producing 437 ft. lbs @4500 RPM leaving the aluminum 2valve 56 ft. lbs.
behind and the iron heads 82 ft. lbs. behind.
When the aluminum 2valve and iron heads
stopped making torque and started going backwards. Our heads kept going
(almost like the Energizer Bunny!) at 6,000 RPM still producing over 415
ft. lbs. of torque. Leaving the aluminum 2valve heads behind by 139 ft
lbs. of torque . the iron head was then behind by a pathetic 177ft.lbs. of
torque.
We then decided to play around with the
jetting and little bigger camshaft and produced just under 600 horse
power. Keep in mind this was all done with our B-2 series head .
Which is what we consider our baby head
due to the B-3 , C-2, C-3, Raised Runner, and HIGH Port, are 5 more levels
above the B-2 series. In turn a 1,000 Horse Power naturally
aspirated small block can be achieved with the right combination.
For those of you out there who
still want more!
You can add a BLOWER, TURBO, or
NITROUS !
Which are all
compatible with all of our 32valve head packages.
