Well it sure took awhile (our fault) but the first Development Warhawk was built and tested by the crew at E/T Performance in Walled Lake, Mi.
As reported by Eric at E/T, all went well in this preliminary stage of testing.
The numbers; 440 cubic inches-4.185 x 4.000. 16.0-1 compression. A cam over .900 lift. Of course a great pair of E/T heads flowing 430 near max lift. Normally aspirated. Seven pulls, 860 HP @ 7500 RPM.
Eric reports that at 4.185 there is .065-.070 sleeve left which is what C5R comes with at 4.125. Engine had nominal temps and pressures at this power level. E/T intends to test to at least the 1200 HP level after PRI.
You can see this engine at E/T's display at PRI or contact E/T for more data. A big THANK YOU to the E/T gang.

16.0:1 compression is not going to run with 93 octane fuel........well it may run, but it'll detonate like a ***** fu#ker!
I want to see a big bore (500+ ci) LSX motor (or warhawk block) built to run on pump gas and see how well it performs.
You know they'll make one with a$$loads of tourque.
And torque my freinds wins races.

Now that is the direction I am going with this ulitmate bad boy GM PERFORMANCE LSX indestrucable iron block. Figure a perfectly square motor with 4.25 overbore and 4.25 stroke makes for a beatiful 482 cubes and with some killer LS7 heads and a great street/strip cam, making a pump gas friendly 11:25 to 1 compression, 650 rwhp NATURALLY ASPIRATED, should be no problem. COuld you imagie that TORQUE!!

You forgot to add a Kenne on it!
If 447ci is good, 482ci must be better!

16:1 and 0.900 lift. Truly remarkable. The geometry of the cam, rockers, rocker ratio, rod length, etc., must have been especially challenging. What can you share with us about cam timing, LSA, etc., and especially cam duration at 0.050 lift?

you know at some point you should just run the engine to a propeller in the front, add wings and never worry about traffic jams again....
machine guns are optional and those of you with navigations systems will find them perfectly useless.
