Not max effort, but not low budget either. Pump gas 535
797hp
697 tq.
I would have liked to try my 1250 carb in place of the 1050, But, it broke a rocker arm before I made any real tuning changes.

On the street? Damn!!

We have plenty of 1000+hp cars on the street around here but they are all turbo or procharged. Very rarely do you come across a street driven pump gas NA car that even has 600hp, let alone 700 or 800.

I know this is street section but JC didn't really say what he's looking for. Just highest na is it. So I guess he needs to clarify his question

Ah, yeah you're right. My bad. Since it's the street section I figured he was looking for pump gas street driven stuff.

I could see a full tilt race motor with big compression getting there.

1250-1350..... Some guys are claiming a bit more but never seem to have a dyno sheet or a trip down the track, or an engine that stays together.

1298/914 with break in oil
7.54@181 at 2800 pounds with an auto trans
7.66@179 at 3010 pounds with a clutch last weekend in Indy
With the weight out (2800 pounds) with the clutch in the fall in east coast air, it will go 7.30’s on a small tire.

John,
Thank you.

I don't know what size your engine is these days, but that should put you pretty close to 1.6 lbft per ci. Very nice.

Stan
