My guess would be 24-26 initial and 34-36 total. Probably close to needing the timing locked out at total timing.

I'm not arguing with you but isnt that high for initial timing? I have had the beast running a couple of weeks. It must be pretty damn close...but I have yet to put the timing light on it yet. Going to do it this weekend. It seems to run pretty good. I have noticed a little hesitation at first acceleration...and a little bump..bump..bump while idleing. Will I hear the ping under the hood or out of the exhaust? This thing is damn loud. 3 inch exhaust to 3 inch super 44's dumped at the rear end turned down. Thanks superbeetle.

You'll need the extra initial cause of the size of the cam you have. You'll be able to hear spark ping from under the hood. I know I could hear mine when I was tuning from under the hood and I just have straight dual exhaust to flowmaster series 40s. You'll have to readjust you distributors advance curve.

My engine has a 234º/234º @ .050 cam and it needed the initial 24-26 timing and 34-36º total. Although, I have mine installed 4º advanced. It doesn't bog what so ever when I mass the gas.

That's my understanding. I'm sure someone else will chime in.

BTW, spark ping will sound like a metal rattle or a jar of marbles rattling.

I should have said it hesitates normal street acceleration...It doesnt hesitate at all when I give it some foot. It must be pretty close. Thanks again dude.

Sounds good. Here's mine running with the timing specs I was telling you about. You'll notice the smooth throttle response as I give the car a little gas to get up the driveway.

I dont hear anything like that under the hood...but I hear a sound like that out of the exhaust everty few seconds..but they are flowmasters. I just didnt notice it before.

True. Might just need a little carb tuning. Put a timing light on it and see what you've got it set at initial and total, and play around with it some to see how she acts.

thats ******.

From the video it sounds a little choppy at idle. My 383 was similar until I went with 30' at idle (26' seems to be the preferred standard but I've had good results at 30' on mine). It keeps the plugs good, gives you a cleaner higher idle, less gas smelling exhaust, and better throttle response.

Theres a ton of posts regarding timing, but with 26 inital you'd have to limit the mechanical weights

You said 22' at 2500?? Youd need 36' at 2500 starting to increase from 1500 I think.

For comparison: my 383 stroker is 9.7:1 , 510/512, duration at 50/1000 236/246
