Its alive - 427 ZR1 edition

[Klaus]

My built 427 finally made its way into my ZR1. Here is the start up. Now getting some street miles before it gets dialed in and tuned.

I need an LS car. Sounds great!

 

[IA Shelby]

That would be fun. What kind of tires are running?

345x18 inch mickey ET streets in the back and 19 inch pilot sports up front.

 

[GTSpartan]

Those cars sound great.

 

[JPKII]

Damn. That is straight nasty. I love that chop. Congratulations.

Sounds really good. How much power are expecting after it gets dialed in and tuned?

Thanks mein. A build similar to mine but with 2650 and frankenstein heads did 1320. I have a ported 2300 and ported LS9 heads which should hold its own with the other set up. LS9 heads flow like a mofo.

But: I am tired limited and I do not want to switch to 15s. This would mean ripping out my carbon rotors which I do not want to do.

So, long story short, I plan on keeping it between 1000 and 1100.

This is the benchmark if you are interested

Wow. Very nice @Klaus
Bad ass man.

Keep us posted.

Is this still the same block or?

Can’t recall specifics, but I recall reading that the LS7 ran into problems with boost because of the long stroke or cylinder wall thickness issues.

Where did the cubes come from @ stroke and bore increase?

Yeah, the LS7s are trouble given thin walls.

You do not want to go over 427 with boost because the stroke is too long.

I am running a sleeved LSA block which should be indestructible.

Nice car, that color is tits

Very nice!
Can’t wait to hear it sing on the dyno. Initial chop is stout.
If you can run 17s those ET Street Rs will hold 1100rwhp pretty well.

The carbon rotors are 15.5. 1 piece 18s are the smallest I can get on. Too tight even for 2 piece 18s (ask me how I know LOL)
