Single planes like a little tighter LSA on the cam...but those aren't terrible numbers for a stalled auto...get it to the track and see what it does. That will give you the real story for this setup...stalled autos are most definitely not dyno queens.

Small cammed automatic with big stall and 4.10 gears? Yeah that looks about right.

On a manual you would be over 400 which again seems fine for a small cam on those heads.

More efficient drivetrains tend to do that, which is all it is...big numbers on a piece of paper. Bet you're lowly 370rwhp car would spank a 400rwhp manual, especially at a track.
