New car, gonna play with the timing tomorrow, opinions?

[mac16]

Ive only had the car 2 weeks and I love it, but I know there is tons of power left in it. Right now the timing is the standard 10 BTDC, I was thinking about advancing it to like 14? Ive already been running the car on 92 octane so that part isnt a problem. What do you guys think, will it be worth it? Noticable power gain?

My setup is: 331, Edelbrock Performer RPM Heads, Performer RPM Intake (Both port matched), XE274, 70mm TB, 80mm Pro-M Maf, 30#'ers, 190 pump. I dont really know what else to list I think thats the most important information.

Thanks guys

My Eddy heads seem to like 14deg..nice place to start, You also need to experiment with the fuel pressure as well...test runs with minor changes of the two and see which ones you like( and the car likes) best.

You should feel a pretty big difference.

it is ~10.2:1 compression also.

not sure how far your going to be able to bump timing. never experimented.

sweet setup though - pics??

im running 18* initial on my stock 302 with just full exhaust and 93 octane car loves it.....

Now how would you know that, unless...........

Yes it is 281pony's old car. Would the compression actually pose a potential risk? If so I dont really want to take it, its just something I wanted to try, would setting it to say 12 make a difference even? I really dont want to take any chances. It will eventually get a dyno tune next spring when it comes out of the garage after the winter.

Compression ratio is absolutely a big factor.

There are no magic numbers out there. You can choose a grade of gasoline you plan to stick with and then up the timing by a degree or two at a time until you get pinging. Then back it down a couple degrees from there.

FWIW, I personally am not a fan of the timing bump game, but that is just me.

Good luck.

i would wait until you go have it dyno tuned to mess with timing/fuel pressure personally.

sounds like a plan . It was just an idea as we recently aquired a timing gun, and I started reading that most people have success with 14 so I though Id give it a shot, but looks like it will probably stay the same until it gets tuned.
