Man, no-one ever replies to a topic about timing. I've tried a number of times and they alwayse say "start at 8 and work your way up until you find the best improvement without detinating"
I could have figufred that out myself, right!??!
Anyway, I think 12 is about as much as you'd want to go. It may even be a little too high. Its hard to say cause those pistons are still fairly new on the market.
BTW... I would love to see your car. Since your in Richmond we should meet sometime.

you gotta use your ears, and eyes, and other senses to tune a car, not a book, it can merely give suggestions, an old motor head friend that has been there and done it before, can be alot of help,
personally my car has considerably more base timing than 12 , i can't remember what it is, nor can i check because its currently sitting on a stand

Hey IROC305 lets do it. Always ready to see a fellow F-body with new ideas. Hey what exhaust are you running? I asked in the AFPR post but I guess you didnt see it. I saw you leave Blockbuster and your car sounded sweet. I actually just met another guy with a 1991 white Z28 with a 305 5speed 1LE R7U. Yes the Players Challange and I even checked the RPO codes to make sure. Nice guy. His name is Darren I think and he even has the video showing his car being raced in the Players Challange series. I think he lives on Aquila road just behind McNair. Thanks to both you guys for the advice. Im just a little paranoid.

I've got Edelbrock headers, gutted cat, 3" headers back into a flowmaster muffler, and dressed up with the 95 Camaro tips!
I have no idea what sereis the muffler is cause I bout the car with it in already and the guy I bought it off of forgot too.
With the new motor I'll just be changing the headers over to the SLP (1 3/4" shorties). I would love to get the Long Tubes but my cars lowered and I really don't feel like listening to hte exhaust bottoming out over speed bumps.

Not necisarily (sp?)! You've got an extra 50 cubic inches and I'm sure you have more compression and a larger cam than I do.
I haven't heard yours yet but I'm guessing it would probably be a little louder and a faster paced rumble with a lower note. Mines kind of a slow rumble and a mid range note because of the lower compression and lack of a good cam. My exhaust really doesn't get too loud until about 2500 rpm and up!
I really can't wiat to hear what my new motor will sound like!

If it is carb, you can buy a knock unit thingy that will screw into your block and monitor the knocking of the engine and come out as a LED display. If it is modified, like mine, I set it to 6 deg and let the custom chip take over. We customed the chip by taking readings and sending it to www.fasterproms.com and they burnt a chip and we took more readings and burnt it again. Now on WOT, it will knock about 1 - 2 degrees throughout the run which is kinda normal.

Sorry I didn't reply sooner... kind of bad weekend, cought a cold. 
Anyway, yeah thast is Shawn's car... 383 LT1 with 15 lbs of boost out of an ATI DS1 blower.
Whens a good time for ya to meet? Give me a shout on my cell 778-772-9393. Just don't dial 604 cause 778 is the new area code for most new numbers. Its still local so long distance charges don't apply.
