I was wondering if this would be good for my 3/4 ton 454 chev truck with the smallest XE4X4 cam.

Dis # 1103433 LG14
weights 41 for both
breaker plate 37
vacuum advance AR35

What's my vacuum advance curve? start-hg/stop-hg/total

How much centrifugal will my breaker plate allow?

What do you think my centrifugal advance curve is?

Would it be better to use my new ZZ4 DIS??

Thanks!

Well, I can't tell you the specs on those parts, but even if I could it would still vary once you have it installed and running. The weights and springs and vacuum advance are all replaceable and you can tune your distributor to your motors liking.

A GM HEI is all that is needed for probably 98% of the vehicles that belong to the owners that belong to this site including my own.

Install it, see what you really have, and tune it from there..

..ditto what Tom said..

Sounds good guys, I'll give it a try!

Thanks!
