Spud Miller:
 Well, I'm not saying lots of luck hasn't been involved :)

 Also, I haven't been doing 6.80's for that many passes. The last 8 seasons have mostly been 6.90-7.20 runs at 198ish. That's one reason I'm going to do some proactive replacement this winter. It's just a matter of time before something fatigues and fails and that would wipe me out for quite a while. My rods and pistons are fancy stuff (BME and Ross) but that's it...the crank is a Scat.

 New crank, new roller lifters, have the rods resized, wrist-pins, rings, bearings...run it another 8 years, right?  :o

Spud, that's great to hear that the One Hot Chili Pepper Front Engine Dragster has been busy in action. I followed your write-up from the beginning since you started restoring the car in 2000. I kept reading it over and over, drooling while watching those small videos (GoPro was not dreamed yet). Superb job Spud!

Larry Gocha:
Spud what kind of compression do you run?

Spud Miller:

 Static compression ratio is 11.2:1.

I'm in awe Spud. What you have done with the OHCP is remarkable.
I've only done some 15 passes with my digger (half those were 1/2 track) and the engine has been rebuilt 4 times! Maybe I'm doing this all wrong lol.

Currently running a 468 donovan, 110 pump, your SM5 (8 amp), and 3.7 gears. 8000 RPM 

I've been thinking about your success........maybe a 2.90 gear to get the revs down further, and a bigger pump to make up for the lower pump speed (my 110 enderlie now has a blank main and 180 psi), and install a Supermag +.

I'm carrying an extra 200 lbs weight over your digger, but that shouldnt hurt too much.

Cheers mate
Graham
