Congrats on getting a 7 in a really heave car!

Looking forward to seeing the results once you get that converter figured out.

Couple major changes before next outing.

Yesterday was a busy and hurtful day on the body. Did R&R on trans for converter swap, and put as much of the top end back together as I could.

PTC put me into a new 10" converter, it will be much tighter than my 9.5". My only worry now is going to be how the car spools. With the 9.5" being as loose as it was, it spooled instantly.

The big question is, how much will the mph pick up and ET pick up.

2nd change are the heads, which has me excited, with a small amount of concern as well. I decided to leave the LS7 platform and went all in with the TFS 245 Hip'd heads that have proven themselves on many other combos out there. They say flow numbers don't tell the whole story, soooo here we go.

Since I have a solid roller combo, these have 1.55" springs, which makes me more comfortable, 7/16" threads for the shaft rocker setup, and the nitrous exhaust porting to a bit of increase CFM on the exhaust. They flow 33 cfm more on the exhaust than my Brodix heads. Of course, I take a 50 cfm hit on the intake. We put a killer set of Ferrea valves in them as well. I've never seen a set of valves with a mirror polish on the face. My expectations are a lot more reliability with this head, especially with the Hip'd option.

Right now I'm just waiting on my Crower shipment, any day, get a quick measurement for pushrods, and probably have it fired up by next weekend.

One more thing, I swapped out the front factory disc brakes for Strange brakes, and saved 44lbs off the front.

Very nice and nothing that would hurt streetability which I love!

I am a little jealous on the Hip'd 245's. I want a set of those in the worst way but needed to upgrade other things first and the Dart LS3 heads are working so far so hopefully next year. I hear they make a ton more power under the curve. Can't wait to see the new results!

When the cage was redone last month, it didn't get back on the scales I was at 3800 before, and I'm thinking the cage swap was a wash, front seats were worth 60lbs, and now brakes being 44lbs. So race weight is still on the heavy side around 3650-3700.

Going to hit the dyno again this Saturday to play it safe on the head swap, then make a couple test hits on Sunday.

Another shot of the interior with the new cage. Still retains the factory blinker tack.

Great day on the dyno fine tuning with the new heads and converter.

Tomorrow the track will tell the story.

Nice numbers! What boost level were you at and do you have a log of your old combo at the same boost? I am curious how the curve compares.

Burned up a plug wire on this pass and it shut down a little early. It probably killed off more mph than it did ET. This was not on the 1600rwhp tune, it was a few hundred hp less than the big tune, so it has promise.

I'm going to get some new tires on it in a couple weeks and head back to Seattle and see how well it runs out the back.

Ya, it shows promise, lol-its an animal-I gotta ask, how hard is it to change plugs.
With just a single I hate pulling #8 plug, lol.
