Friend has basicly stock 502's with 250 B&M blowers ,single 1050 carbs . What sould max timing be ?

Also how should this carb be set up ? What jets and power valve if any ? THanks !

Thanks ,JOE

Now your talking my language.

Mine is a 502 with roller cam, ported heads, B&M 250 , 1050 Dominator.

The B&M manual says 28 deg max. When I had my motor dynoed last month, the operator said it liked 34*. I'm staying with 28-30 for comfort. I ran 28* last year and spunit at 5800 with no problem.

THanks us1 fountain ! THats what I thought but couldn't remeber . It is amazing how much you forget over a winter !

Do you run the V-6 module on the thunder bolt ? He doesn't have it yet and I wonder if the V-8 one will work . I think his initial timing will be way too low if he sets it at 28 degrees . What do you think ? My motors are a lot big then his and run 28 with the V6 module . But I don't know if his needs it or not . Thanks ,JOE

Hot Boat,
i would like to see the info you speak of, as would others i’m sure. if you can post it that would be great, if not able to, or too much info to post can you please email a copy to me?

Boot,

I'm running a V6 module. I've tried it with and without. the module gives a much smoother idle. I set the advance at 28 and let the base fall where ever the module put it. (I think around 12 - 14). Should work for your buddy.

Hot Boat,
Is the timing the same with or without an intercooler? I have coolers. Thanks

you guys should switch to an msd set up , if the thunder bolt fails the motor will stil run an you can say bye bye, if an msd fails the motor will stop

Huh???????


Boot,
Yes, I'm using the V6 module. Never tried it with my V8 module as I've read/ heard the same as you about the timing at idle.
