Finishing up the assembly this coming week, then I'll schedule some time on the dyno.

Anyone care to take a guess at what she'll make?

*4.030" x 3.500"
*10.5:1 SCR
*4V quench heads, little port work done, not by me...
*Customer supplied camshaft, Comp hydraulic roller, 230/236, .650/.660", 110 LSA, 105 ICL
*Blue Thunder dual plane intake
*Holley 850 Carb

This was an engine that came to me in pieces...customer already had most of the parts, just wanted me to assemble. Should be a very nice stock stroke build.

515 if you do tuning sweeps, jets, timing

hold that. 110* on 105*... will hold down rpm which in turn will limit calculated HP

i'm going with 410 ft/lb

there'll be phantoms, there'll be fires on the road... and the white man dancing

The heads have been hit pretty good, but the bowls and valve guides haven't been touched.

Desktop Dyno is saying about 450, but it's usually a little high compared to the dyno.

Dynomation predicts anywhere from 420 to 490 HP, depending upon which set
of head flow numbers I use (ported or unported) and how good the Blue Thunder
dual plane is. In our testing, the unported Blue Thunder had problems with
4 runners being much worse than the other 4. The unported Blue Thunder was
down some 31 HP to a ported Ford aluminum dual plane (Boss 351 with Holley
carb pattern). A Holley Strip Dominator made another 15 HP. That was on
a 5500 RPM peak 408C. Later testing showed an Edelbrock RPM Air Gap was
better than an unported Blue Thunder but the ported Blue Thunder bested it
and matched the power of the Strip Dominator with better average torque.
If the engine doesn't make the expected numbers, sse if you can borrow an
Edelbrock RPM Air Gap and/or a Strip Dominator. A Holley 950HP would
likely work better, too.

With an unported Blue Thunder and ported heads, I'll guess 440 HP.

If I guess closest, will you grind me a cam for free?
I'm ready to have a cam ground.

My guess is 437.4 hp.
