Firecore distributor set up... Opinions

Hi all,

I just picked up one of Rich's distributors and am really excited to run it, but I thought I would get some opinions on set up for tuning it for my street/strip set up.

72 road runner with 9:1 comp 440 915 heads with comp valvejob, lunati 303 cam and a edelbrock rpm intake, 750 DP Holley, 1 7/8 headers, 727 with 4:10 gears

1)Looking for recommendation on initial and total timing

2) at which RPM level should I have total timing in by (3000, 2500, etc)

3) which springs to use


Thanks all

Mikey

why not just ask Rick?

I'd go with the lightest springs... I like to have my advance all in by 2000 at the latest. I'd shoot for 18-22 initial and somewhere around 38 total ( not including vac. advance). That's where my Satellite was when it was similar to your set-up. I run Ricks distributor and love it!!

initial: with "vacuum gauge method". total: 36-38. springs: any combo that puts you just under the pinging point at WOT up thru the gears on your hottest/driest day no matter where (RPM) that makes the springs max out at. IN ORDER & if the vac gauge method when done makes the starter cranky when hot then reduce the initial timing 1 degree (not the in hg vac #) & repeat as needed (reducing it another 1 degree of timing if need be). EDIT then plug in/adj vac adv if used

This is a good range for initial that should work as a starting point. Find the point the where the starter kicksback as your initial limit and start tuning it up.
