I don't know if this the best place to ask this but....

I need the right timing curve for a 300 CID straig 6 engine, carby, the springs inside my distributor are lost and here in Venezuela is not so ease get timing kits so I had test with several springs but I need know the proper timing curve

Thanks all...

 

The distributor in my truck is marked as 20* at 3400rpm, which is the peak hp rpm for the 300-6. This is just the mechanical advance, and should be about right for your engine as well.

 

Ok I'll try that

Any extra comments guys??? Thanks
