No my last set-up ran on pump 93..... and race gas at the track....
Drove the car as a D/D for 9 months straight all thru last summer and winter here.
Did it because i had to.
The wife and I went to toal different directions for work.
45 miles round trip every day.
100+ miles on the weekends.
I would run about 14-15 psi on pump on the street.
Was a blast...... just drank fuel like it was going out of style LOL
Now the new motor....
It can be ran on pump gas to drive on the street..... like almost any of these cars could..... now im staying out of the Boost..... thats where ya get into trouble....
Prob wont do it much......
Its time to get a lil more serious

how much preparation is done to your block?,
gaskets?
my build is similar to yours engine wise, but im going tt
62-1 t4 tnetics, 370ci, part fill block,
6.0 h beams, stock crank, 1.425ch pistons 23cc dish
317 heads

lets put it this way IM paying 1200 for preperation and assembling the short block...Im going to pay more to balance the rods and pisstons and crank soon. the reason im going 8 to 1 is because I had the pistons and rods and crank from an old block.
As far as a cam goes I will be calling cam motion to spec me one out. Im assuming it will be rather small. reverse split 220s and 560s lift . I would like more lift then that though. my last cam was 218 214 564 546 on 115 and went 10.2 on 9 pounds
cam worked great haha with the motor

What size turbo are you stepping up to now? I should have it in my hands next week.
Its a new one im testing.
Swapping to an A2W set-up and going with BS3.
I hear ya about the driving....
I need more seat time for sure......
Since the last motor was crap..
They coated the piston skirts instead of ordering new pistons.... the pistoned moved in the bore to much..... stock crank was flexing.....
So a lil more cubes and some O-ringed heads with copper gaskets....
Id like to hit the Cage Cert.
Whats up with your BEAST

It will be a double O-Ring set-up with copper gaskets......
As of now we dont even have any results on how the 6 bolt stuff is doing under extreme Boost.

i'd push water boosting down the street with 15psi and 16*, but thats on 93 pump. i think i need to make a better overflow setup, but obviously thats not the cause of my problems.... my headgaskets were poop the past two teardowns
assuming you have an aftermarket overflow, is it a sealed setup, or is there a vent-hole/breather? my jaz had a pinhole last year, and when i'd beat on it, coolant would **** out of there... i sealed it this year (probably not a wise decision)... regardless, i was constantly down about 12oz, and it wasnt going into my oil. i WAS getting oil in my coolent

The bump in compression really helps out....
My new motor is going from 8.87:1 to 9.5:1 , but ill be on race gas all the time so im not worried about pump gas.
