I like this change.

The chambers were opened up a bit around the valves, but then shaved back down for a net increase in compression from 10.3 to 10.6, plus I advanced the cam from 1* advanced (4* advance minus 3* of timing chain stretch) to 8* advance to bump dynamic compression up as well, and in theory bring the power band down some so at cruising rpm it may be a bit more efficient than before. Plus the new exhaust and I have a couple other tricks I want to try out.

I think I'd make out if we swapped gas card bills Randal

Anybody have the link to the complete 2013 rules?

**I'm also a couple of seconds slower than you.

After I install the 9" rear I'm crossing my fingers to dip into the 11's. I'm thinking 4.11s and a spool for the week?

Skip the spool, get a Tru-trac.

tru trac is a good way to go, I have a locker, it works ok too..

Buying into Neals' fantasy of no rain. Me too.

I don't really think you're seriuos... but what those guys said. Have you driven a go-kart with a live axle in the rain ? Damn thing steps a foot to the right when you let the clutch out. Drifting as a daily driving style can be interesting. Left turns are kind of fun, right turns sometimes just don't happen.

No Fantasy, looked at my Mayan calendar and it said no rain..

Wait, Oh shit.....

Truetrac!

I was thinking when I get the 9" I'll get ~3.23 with a normal positraction carrier, or tru-trac, but that ratio doesn't really do well for keeping the engine in the power band. Much like last year I was crossing the finish line at 4800 rpm and barely into 4th gear, but maybe a 3.55 gear will be a good compromise and get a tru-trac or locker. I was thinking of getting the 4.11 spool for a swap out set.

[squirrel]

you need to think Ford gear ratio numbers....3.25, 3.50, etc.

btw I ran 3.25 gears on DW in 2011, the whole time, worked ok. Not quite enough gear at the strip, a little too much on the road, but I don't have OD.

If I don't get a GV, I'll probably run 2.47 on the drive to BG and home, and 3.50 or 3.70 on DW.

edit: btw what was this thread about?

Consistency.

3.50's should be a bunch still available from trucks.

Randal likes playing with things at the track ... six months, get some seat time with a stopwatch and see what the 4.11's do for you?

3.89's, a spool, Bias Et Streets, no problem for 4 days. Add rain on Day 5...Big problem!! One guy with both handsfull of steering wheel, the other guy with both handsfull of roll cage!!
