Got my car dynoed, looking for more power. (dyno sheet insde)

I did 6 pulls, I don't know why I don't have the 1st pull on the sheet though

Anyways I just wanted to dial in my a/f ratio. I had to adjust the f/p after every pull, and it just went lower, which is good. I think I ended up around 12.0-12.8. Still a little leaner than I want, but I can bump the f/p a little more.

I think I did, OK, I guess. My guesstimate prior to the dyno was 320rwhp, and I was damn close I kinda want to get up to 350rwhp now. Which I "think" might be possible with a little here and there, but mostly in tuning.

My timing is at 10* (never touched it during the dyno, too busy with the a/f) with Autolite 23's @ .035", with 6psi.

So how did I do, any suggestions on some easy hp? I don't want to run any more boost, but IF I do, 8psi will be my max, until I get some rings for boost, then I'll be putting down some nice power

I have stock replacement TRW pistons, which are forged aluminum. The compression is stock, I did have the orginal rods reconditioned, put in a windage tray and I have a Crane 2030 cam.

I don't really want to change the heads, and if I did they would be some variation of GT40. I can't afford aluminum heads. I'd like to take out the motor and maybe put better rods in, and better rings for the boost so I can run more without worry. But it's fine for now. I happy with how the power feels.

Why not an FMU?
