seen you were building a 370 with a d1sc, and you had the 823 heads. what was the out come i am debating wether to go with the 243 or the 823s. i already have the 243s hand ported and will git them reported and valve job if i go this route. but just wanted to know whats your opinion. intake recomendations would help aswell thanks. pistons are je 288005.
243s compression would be 9.5 to 1
823 would be 9 to 1

Hey Zippy,
Wife's: 2002 Tahoe 2wd, 408, 4L60E, 3.42, Gov-Lock, 862 heads milled .015 with 2" Ferrara stainless intake valves, Patriot Dual Gold springs, 224/228 113LSA, 160º thermostat, Pacesetter 1 3/4" headers Zippy Programming.
Whats the rwhp on this set up, and whats your opinion of Pacesetter LT's for an LS1 T/A, I see your a tuner here in the Valley, do you work for a shop?

No problem. Do you have tuning software or do we need to do this through sending a pcm? Feel free to call me if you want.

Hi Zippy,
You did a custom tune for me a couple yrs ago and my truck has remained as tuned since. Running Great! I would like to upgrade to a LS3 TB and 90mm J Tube with a Dr X link. Can you make the adjustments for this upgrade without doing a live tune?
TIA,
Mike

Well thats good. Glad everything is going good for you!

Not bad, but cold. lol Just working and gathering stuff to put my 5.3 in my 89.

Yep, moved to a new job in Arizona. It was a good opportunity for me and I really couldn't pass it up. How are things back home going?

You moved again? I see it says Arizona in your location.

Yea he is selling it now when its fixed. So if you know anyone that might be interested in it let me know.

Nice! Thats a good gain from headers on a cammed truck. What brand headers are they? That would be awesome with a 408.

Sucks to hear about your old truck. I am happy with the results from my truck with the headers. It picked up 35RWHP from that. It's a noticable gain everywhere in the powerband. More to go, but trying to get a 408 done by next year for it.

I hear you have long tubes now? Bout time! lol That thing has to scoot now!

In other news my old white truck lost number 7 last night. I helped him get it apart today. I'll have to send you a picture of it.
