When it was my time to drive and him on the passenger seat, going from a Vette to a tiny Abarth was scary for him. The only thing I told him I was a Kart racer and he was like "Damn, is this how it feels like to drive a big Kart?" He didn't last 2 laps! He hated going airborne! 
He did tell me that I did a fantastic job on the driving but the clinic was about the student and my safety, a lot of psychology involved.

I taught driver training for 4 years so the in-car is easy, and I started in autocross almost 40 years ago and moved up from there. Yup, I'm one of those old guys. As to what I said to the other instructor to get him faster? "The tires are telling me things that I don't think you're hearing. Listen to them and join the conversation."

Just sent you a PM regarding your custom intake. I'd love to see what you came up with, as I'm considering doing something similar myself.
As for your new project La fiera, I'm really interested to see if you hit your goal. Your 250 hp build thread was an informative read that I thoroughly enjoyed. I'm looking forward to see how this one plays out as well!

Hello Irrarionable!!! Can't wait to meet you, you are my neighbor! I'm glad you enjoyed it , and got something out of it to move forward with your project. That is the reason I do what I do, to learn and pass on knowledge. Anything I can help you will be my pleasure! And if anybody needs some advice on anything, if I have an answer I'll pass it on, we are here to learn from each other. "There is more happiness in giving than receiving" the son of the Almighty was quoted by the apostle Paul in Acts 20:35. 3.4 DOHC have a LOT of potential, so you are on the right track!

Sorry for the lateness but you know how it is with projects! Got my rods and crank from the machine shop. Equally matched in weight!
If you go back to the 1st page the stock rods are 590+- grams. The Supernatural rods are 542 grams and the crankshaft had to be lightened 1/2 pound to match the lightening of the pistons, pins and rods. These rods are Shot Peened for strength!
The stock pistons are 488 grams and the Supernatural are 435 grams! The stock .906 pins are 142 grams, the Supernatural .912 are 106 grams!
I already have the camshaft profile (Attitude) made for it so the short block is pretty much finished. I'll use the top end from the 250WHP project with some improvements that will boost its VE. One thing I learned with the 250WHP project is that if you put limits on yourself (Iron heads), your creativity will increase to levels you will not believe!
Don't believe me?!! Look at F1!! The more restrictions they put the faster and powerful the cars get!
But for the fans I can't start on this one until I get that 250WHP Dyno sheet on paper and video. Stay tuned![This message has been edited by La fiera (edited 06-28-2018).]

I admire your engine building skills, but pulling 250HP from a 3.1L N/A build is setting a goal of nearly two horsepower per cubic inch. That is a very aggressive goal for an engine not known for its breathing. IMO, you will probably need a turbo so prove me wrong. Interesting thread. ------------------

Hey Dennis!
This specific project is over 3.5L with a goal of 300WHP using the same 3.4L block and iron heads. The 250WHP @ 6000rpm project is already finished and accomplished. But once I install the trans its going back to the Dyno so I can video it and have tangible proof that it can be done without a turbo or nitrous.
I personally like to use the "Heart breaker" of Dynos, the Mustang Dyno; so nobody can say I'm cheating the system. Sit tight and be patient, I will not dissapoint you.
Is there any way I can see The Paralyzer and The Colossus hp output? Did you make a build thread? Maybe there is something I can learn from your builds!

You still working on this? If so did you consider solid lifters? They have .842 lifter bores so you can use sbc/ls lifters, right?

Look at this thread. That's what I'm using now in the 3.4 250WHP Supernatural. SBC solid lifters.
The block is in machine shop getting the last bore correction to fit the pistons. The only difference between the 3.4 and 3.7 is the bore.
And of course, the entire rotating assembly is lighter. But to answer your question; yes, I'm working on it. I should have the the short block ready
in 2 weeks. I will not install it right away. I want to see how much more I can squeeze out of the 3.4 Supernatural and then the 3.7 will go in.
