Something like this

Exactly what I had in mind

Sorry for clogging the thread with my bs. Glad you're getting the ac stuff sorted out.

How does the power feel compared to before the heads?

Oh man I genuinely didn’t expect this much of a power difference, with the old heads it was difficult to break the tires loose once rolling even in the rain. Now, in second gear at 45mph it will blitz the tires and start slinging sideways like it’s a drift truck. It starts to pull so hard above 6k it’s pretty savage I’m in love again. I actually re-raced a RCSB V6 non turbo f150 that I raced in the past and won with a decent gap. This time it was Yukon XL lengths on him and he had no hope to hold even from a dig or a roll.

The tune is definitely not even close to being finished and I think it wants a good bit more timing in the mid range, I’m hoping I can tune some mpg back into it because it’s been getting 11.5-12 so far. But the crazy rich idle and idle swings must play a big part in that.

I'm pumped to hear that! I'm was worried that it wasn't going to be worth the hassle. Gives me hope for when I finally get off my lazy ass and mess with mine. I'd love to find some more power because mines just a few clicks above stock lol

I wasn’t so sure if even feel the difference with the heads but it’s night and day. You need to tune your shit! If your AC is working and it drives like it should, it will be cake to tune all you have to do is play with fueling and spark non of the frustrating stuff.

380 is for girls. Ruger makes great stuff but I personally carry a Sig P365 and love it. 15+1 9mm, a light, and optic. I carry in a Trex arms sidecar apendix holster.

I can't hide that in my butt.

Barrel is only 3.1” long, must be the girth your concerned about.

It runs and drives fine. Just has the weird "whoooosh" at start up we're it takes a deep breath, exhales and then comes back to normal idle. It also hangs the throttle if I rev it after it's warm. Oh, and has a dead spot in the powerband from like 1800-23/2500 ish. Lol

I can attest to him consuming at least 3.1". Girth, that's a whole other conversation. Although, I do recall a "jar" incident that I found quite intriguing

Long and thin slides right on in. Short and thick makes it rip.

So, all around your cruising RPM range?

I totally would've guessed 3.768" at a minimum.
