Numbers are SAE. How is the graph looking? Are the dyno numbers where they should be or is there some power on the table? I'm also guessing the 103F temperatures didn't help things

I would have expected it to make more.

Looks good for the mods and all dynos vary so its tough to compare.. Since those are SAE numbers the temp in the shop doesnt matter since its corrected. What exhaust do you have? cut out?

Same that's what I felt. What's holding me back?

I have a 3" ORY into a Borlamouth (SLP Loudmouth) with no cut out. I just thought it would have been around 440-450 for what I have.

Who ported the heads. Numbers seem good to me

Looks right on the numbers as far as realistic numbers to me. Sure someone else may make more but stock cubes and castings only get you so far.

My V made 440/390 with a v3 and tsp stage 2.5 heads with a ported 92/90.

Yeah thats a good free flowing exhaust and a cut out would prob just make it louder inside the car. Id be happy with your numbers for sure. 450 with that setup would pretty generous.

Bought them off a buddy who had a guy from Manley hand port them.

Cool, just seeing what usually this set up pulls.

Would I benefit by stepping up to 1 7/8 headers? I'll be looking to get cut outs over the winter since it can always be louder . Just trying to chase down those last couple improvements before I would need to step up to a bigger cam and aftermarket heads.

By the way, guys with the Torquer V3, how often are you changing valve springs? I know these LSK lobes are rough on valve springs...

Yes you would benifit from the headers upgrade

Its a hit or miss. When my pacesetters rust out ill give the 1 7/8 headers a try.
