Hot damn Archie! Great torque numbers. I would have guessed more hp by the way it runs on the street/track. Heads and cam combo should make for a real sweet boost.

Thanks Bill. I'll get that horsepower up there.

Stock these L31 engines put out around 190-200 RWHP/260-270 RWTQ. So I think its doing alright for being a stock longblock.

Congrats on the numbers!! That thing is making a lot of torque. Definately different than a Gen3/4 conbo where torque and hp are close. The huge rear end has to be robbing a bit of power as well.

You going to turn up the boost?

I'm going to leave the boost where its at right now, I'm going to look into getting some heads and a cam first.

Great job! Those are some big numbers for a stock motor. Looks good too.
