Numbers do seem low but if motor doesn't have any mechanical problems that intake I am sure is not optimal at all for 427 cubes. Even a ported intake would be worth Probably 15rwhp. Most guys running those big cubes need an aftermarket intake.
My buddy had a mild 408 ls2 and even with a ported ls3 it wasn't enough. He went with one of those high ram types... can't remember which one it was years ago in a 2000s goat and he jumped like 25rwhp. |

Remember end of the day the dyne is a tool, go to the track and get some numbers, your mph will tell you how much power you are making.

When I had my Dyno tune done ,they did the same thing handed me the sheet and just had the rwhp and no tq. I had him go back and in and print out with both.
I really don't get it ,tq is just as important or more than hp! When I'm paying for a Dyno tune I want both . I know of several well known professional racers that will tell you ,never trade peak tq for peak hp. At least for na anyway .So why would they give half a tune sheet is beyond me!

Ya honestly I'm not worried about the HP or torque. I'm worried about power drop off at 5900rpm which is the main issue, should be producing power to around 6500rpm. Spoke with TSP already, salesman is talking to some people and getting back to me.
