Everything in it now is the best money can buy so it is a bargain.... the reserve price is less than what I have in the last engine build.

I've watched you and I understand. Enjoy the other cars and keep in touch.

It really depends on how much power the car is actually making. The short answer is 1400+ horsepower, over 4000 pounds and a lot of racing events. I drag raced it a lot for a while and was running consistent 10's with the clutch. I haven't checked the boards for a while but at one time it held the 60 ft record for drag radials and a manual transmission with a 1.49 60 foot time. I would take the engine to 6000 rpm and then dump the clutch then just after it launched I would put the clutch half way back in while holding throttle wide open and let it slip so it would not bog....good times but broke some transmissions and smoked some clutches....It has got a $6000 dollar clutch in it right now. The engines always let go either road racing or running the mile. I had a problem blowing the head gaskets with 1400+ horsepower and running the engine wide open at a racing events. A lot of the time, by the time I got the car shut down, what started as just a blown gasket turned into bent rods or worse once the water was in the block. It all happens pretty fast at 200 mph. The first block I had o-ringed the horsepower fractured the actual head...this was an expensive set of trickflow heads, destroyed the whole engine. Now it has some crazy custom stuff from LME, o-ringed and supposed to handle 2500hp. If you make really big horsepower and actually run the car at crazy speeds and not just zip it over the dyno it is really tough on the metallurgy. Even 1/4 mile racing for 10 seconds or less is pretty easy on engines, if you want to test a big power engine hold it wide open for a minute and see what happens....

Looks like the reserve has been met

Thank you for the rather complete response.

Sorry to hear this Jess but I understand. I’ve also been following your builds when they were up and down. Also received some great input from Andy at ADM.

Appreciate all the input you provided on this platform. We basically learned what not to do with your R&D. Thank you!

I still have my 2016 but it is much more tame than this 2013. I used to say there was no such thing as too much power but when I started going sideways at 150mph I started rethinking that a little. Always glad I could help on the boards. I'm planning on going back to road racing more and will probably keep a stock engine for a while just to prevent the big failures. I suspect I will crave the power and eventually make some upgrades.... time will tell.
