Had a great time today. Very nice to meet you, Greg. Thanks again for snapping some pictures for me. They turned out really well.

Those are some impressive times Greg. I know you are running a roush 427 but can you tell me more about your setup. Gearing, Hp, tires etc...?

The Roush 427R is the basic deal with single plane intake. I got rid of much of the goofy stuff that robs power and some other stuff that might break, so now the motor can put out close to what it should at the wheels with reasonable reliability. It's about 475 HP at the wheels now. The performance and reliablity things I changed to from how the car was delivered are:
1000 cfm Pro-Systems carburetor
S&B taller oval air cleaner
8AN (1/2) fuel line from tank pick up to carb
Aeromotive 100 micron fuel filter
Upgraded half shafts from The Drive Shaft Shop
Detroit Tru-track rear installed inside the Ford 8.8
2 inch primary headers
Buckshot Racefab stainless side pipes
McLeod light weight flywheel
SPEC stage 3 clutch
SWI engine mounts

I have a set of 275/60 15 Mickey Thompson ET street drag radials. I drive around town with about 21 psi and also the same at the strip I've found works well for the casual starts. Just start from idle and nail it. That's about it. It has the stock Superformance IRS design and the basic TKO 600 with a 3.73 rear gear. The tires are 28" tall.

As someone who drag races a lot I wanted ask your opinion of how much time you think you would loose with a 3:27 rear end. That is currently what I am running. It sticks very well but I have been toying with stepping up to a 3.55 or a 3.73. Obviously faster is better but I dont want it breaking loose every time I get on it either.

I've only had this particular car to the drag strip a few times with club events, but as I understand trap speed should be pretty much relative to the power the car has on the particular pass and very consistent. As long as you're not running out of gear on the top end the rear gear ratio shouldn't make much difference for the trap speed. For the time it improves or worsens greatly as 60ft time changes. Harder launch and gear ratio to improve on the initial start would improve time. Every .1 second give or take for the 60ft = about .2 at the end.

I think the 275/60 15s Mickey Thompson ET street drag radials would hold quite a bit more power than I have. It just comes down to the track conditions for the day. On the street they're incredible.
