Only the drive back from your shop and then to the track, which wasn't enough to know for certain. When I get it running again I'll be able to do some actual mileage testing (I'll take a roadtrip. :)...

Well, it wasn't the end of the weekend I had hoped for either. ;) But the car performed great while it lasted. I had other gremlins that kept me from getting the most from the weekend, but they were...

I autocross as well as do the track days, but there is no comparison on the fun level. The 30 minute track sessions blow away the 45-60 second auto cross runs. :) Of course there is a price to be...

Me too... On both statements. And turns out it's the first that Tony knows of as well.

The car was running great! TOW is a handful on the track compared to the Porsches, BMWs, McLarens, Ferraris,...

I've owned them for about 2 years. They have been running in the car for about a year. I've put perhaps 500 - 600 miles on them. I ran a 2-day HPDE in February, driven a good number of street miles...

Correct, although my engine builder did double check everything during assembly as well.

I have spoken to Tony, and it seems that I'm the first person to have one of these new-generation YT...

I can do that... I expect that the aluminum rocker arm would have let go before the pushrod would have bent if there were a piston/valve collision, but a better check that rolling it on a surface...

I pulled the valve cover back off and removed the rocker assembly. I found the broken chunk with the adjuster. The rocker is too beaten up to determine how much is 'missing' at this point, but I only...

Haven't pulled the pushrod yet, may do so tonight. After I saw the brake I snapped the picture and put the valve cover back on to prep for the trailer ride home. After two days in the Texas heat over...

Not a clearance issue... The broken one does appear to be touching, but that's because it's been elongated now I believe. The others do have plenty of clearance. They will move away from the rail as...

I did not. The car had been sitting for about an hour before I took that picture though, and the oil was hot when it let go.

I hope as well... I'll remove a few things and see if the pushrod is still there, then do a leakdown test on the cylinder before I pull anything apart. Spring and valve are still there, so I hope the...

It's been a really long weekend (two days at a driving event at COTA), and it unfortunately ended on a bad note. I'm way too tired to go into all of the details now, but the following picture pretty...

Thanx Scott. It was good to finally get the numbers and know that all of the effort and cost brought me a worthwhile gain.

Hopefully both the car and I will survive the heat this weekend at COTA!

Thanx. The other things I didn't mention were the T56 Magnum and Ford 9" which eat some power, but really this was all about the improvements vs. the absolute number for me. I'm very happy how it...

I'm curious, can you tell us which intake that is? I dynoed my 434ci with 2 single-plane intakes, and I'd like to know which was used here for comparison. It honestly doesn't look like either of the...

I can offer one LS3 data point. I've posted my dyno results here before for a couple of combos now. My LS3-based setup was a 434ci, LLSR from Cam Motion, and TFS GenX castings which had a semi-custom...

FWIW, when Tony was developing his MMS 265 heads, he originally started down the path of using the Brodix castings instead of the TFS. If I recall our conversation correctly, he switched to the TFS...

Probably more accurate to say that it started life as the TFS GenX LS7 porter casting. I believe the 260 would be TFS's ported version of the head. I'm pretty sure that Tony starts the port from...

Did you decide on a cam? Who did you go with, and what specs if you're willing to share? From what I've ready, you're sticking with the MMS heads and Tony-ported MSD intake, correct?

No I didn't. The pads on the intake where you will bolt the brackets to, at least on my intake, are at an angle to the plane of the fuel rail. So I installed the injectors into the rail, seated them,...
