That is awesome making it into the 10s!!!

It sounds really strong. We went from 1-3/4" primaries going into a 3" collector, to 2" primaries going into a 3-1/2" collector. Then we sent them to Jet-Hot and had them ceramic coated. That really helped reduce engine compartment heat.

Yes that's right, we're running a 390 block, bored 40 and a Scat 4.250 stroked crank with Scat H beam rods. Heads are C4AE-G with 2.12 intake valves and 1.71 exhaust valves. The heads are mildly ported. Intake is an unported trick flow track heat. Pistons are RaceTec, right at 13.1 compression. The rockers, shafts and supports are all P.O.P. Thats the build, kinda of in a nut shell. The transmission is a C-6 with a 10" converter. The rear gear is a 9" with a 31 spline spool with 4.11.

Well we finally got the Mustang down to the track Saturday. Now the only big change, was we went from an 850 double pumper to a 1050 dominator. We really didn't no what to expect. So the first run we took it kinda of easy, and it ran an 11.67 @ 117mph. So the second run, we left off the 2 step and shifted at 6000 rpm. We ran 11.57 @ 117mph. The car just kept getting better every run. We got 5 runs in all together. Made 3 elimination rounds, with breaking out on the last run with a time of 11.501 @ 117mph. The track we race at is Bandimere, the track temperature the last run was 130 and corrected altitude was 9800. All in all it was a great day at the track. Saturday was a points race, but we have one more test and tune before All fun Ford. So hopfully we can dial her in a little better. The car was a solid 11.70s with the 850, now it seems like its a pretty solid 11.50s. So the 1050 seems to be worth 2 tenths, at least we're going in the right direction.

Hi everybody, I just thought I would give you a quick update on the Mustang. We haven't made it to the track yet, been just to busy here at the shop. But that's what pays for the racing. Last night we started getting the 1050 fitted to the intake, as you all know it's a little different set up then the old 850. Another piece we are changing is the thermostat housing. The top radiator hose came off the stock Ford thermostat housing last year in the trailer after we had made a run. Thank goodness it didn't come off during the run, that could have been very bad. I know we should have made sure the clamp was tight, but we had no indication we had a problem. The new thermostat is a Billet Specialties, its has a nice lip around it, way better then the stock housing. It's O-ringed sealed and you can adjust the angle. The one other update is we're replacing the stock steering colunm with a Motion Raceworks chromoly steering column. It should be here next week.
Well that's it for now.

I feel your pain, the same thing is happening with our little foxbody. Five years ago, my buddy called me up, and said the kids are grown up let's go racing. He had a 410 sitting in the shop doing nothing, and I had a car that needed a motor. So we agreed as long as we can get into the 12s we would be happy ( NOT ). Five years later were running 11.5, and were still looking for more. It's just the need for speed in all of us.

Will do, we're headed to the Tri-State Automotive swap meet this weekend. Hopefully will find some cool stuff for the Mustang. Seem's like we always come back with 9" spool. In the last 3 year's we've pick up 2 31 splines and 1 35 spline, all under $50.00 a piece.

Well it's time to get the Foxbody back in the shop to get it ready for this year's race season. We're not doing anything to big this year. We're changing carburation. We've been running holley 850 double pumper, but I picked up an older 1050 dominator, so that's getting installed. The only thing that sucks is we just got the 850 dialed in. We just want to see what the dominator will do, hopefully it will make us faster. Can't wait to get to the track and see what happens. The only other upgrade is, were going change the steering column to a Motion Race works chromoly light weight steering column. The biggest reason we're going to that, is so we can remove the steering wheel. That way I can fit my Oversized (you know what) pass the roll bar. Well that's it for now, I hope everybody having a good winter.

We are running those same heads on our 445. Just FYI we had to raise the stands 110 thousandth to get rocker geometry correct.

We use the Concept Design Engineer valve spring compressor for FEs, and it works perfectly.

Here's update on the 79 Foxbody. We had a good season with the Mustang. The down part of the season was we only got down to the track twice this year. The good news is the car is getting faster, but we only got 10 runs in. We spent $2000.00 and only went 3 tenth faster, but that racing.
So the changes were going do this winter is, new steering column so we can remove the steering wheel. Then I can get my fat butt in it, and race it myself. install a starter retard box, then we will lock out the distributor, and the last big change is install the 1050 dominator.
Well that it for now, let you know how she runs in the spring. Clint
P.S. Boy I love FEs.

We're launching at 3000 rpm off a foot brake. The 60' time's are not great. They around 1.65 with the best being 1.61. I think one of our next steps is a different converter.

 Yes he said it was still pulling hard when would shift. Everybody on the race team wants to bring the shift point up to 6500 rpm. I guess it's time to turn it up. The engine has been built to do it, so lets see what happens. Clint

Quick update. Took the Foxbody to the track last night, and just played with timing and main jets. Got three runs in. Went down to 87 in the front and 88 in the rears, ( because we didn't have 4 88s ) and set the timing at 38. First run it ran 11.71 @ 108 mph car got a little lose at the traps so my buddy let off. Pulled a plug and it look pretty good, maybe a little rich. Kept everything the same for the next run. It ran 12.01 @ 112 mph. Have no idea why so slow. Pulled a plug it looked real good. We have been shifting at 6000, I told my buddy to shift at 6300 this next run. It ran 11.53 @ 117 mph. That is the best run to date, at least we're going in the right direction. That's it for now.
