Cam Spec.’s for GM’s new 1000 HP pump gas engine

[tjs44]

So the 1000HP should be 40 percent more?Tom

[bob460]

22-25k i would think.

For someone who has a pro street car..............this would be the ultimate engine.

[Rick!]

For reference, the Helephant 1000hp was $30K plus $2265 for the engine management kit, before Let's go Brandon.

No way thats 100k lol just a fill in number because they likely dont have the price out yet

10s of searching on Google confirmed this. That number is just a place holder and maybe purposely there to generate buzz.

[David Redszus]

1000 hp @ 7000 from 632 cuin is only a BMEP of 12.3 BAR.

Quite a few engines are capable of that level of performance.

[HDBD]

Wonder what lifters they are using?

[EDC]

Any cylinder head details other than the basic valvetrain?

Curious about the port layout and chamber configuration.

I would assume peak hp would be closer to 6000 rpm

[Roundybout]

I think it was closer to a BMEP of 14 BAR or so.

Torque 876 at 5600RPM
HP 1004 at 6600RPM

I’d love to see the dyno graph.

Roundybout the dyno graph is on Danobee's reply The GM link

I'm curious too! Googled the part number 19431810 and got the same info previously posted.

Wonder what lifters they are using?

I am guessing a .937” diameter body with a .850” wheel riding on needles ? Mark H .

No one make's a hydraulic roller lifter in .937........that i know of.

Must be a morel or johnson .904 lifter .810 wheel.........don't think std size lifters could handle .780 lift for too long.
