Pump timing?
 

I'm getting a rebuilt pump put in my truck and I was wondering what degree of timing would be the best? Thanks in advance.
1997 cummins with 62 over a 75 compounds 7X.14 injectors, 4gsk, .024 delivery valves, airdog 150, 5 inch exhaust, watermeth injection, ported and polished head, fire ringed and studded.

Depends if you plan to run it in winter or have winter where you live. Generally more timing more power and with a 62 im assuming 65 turbine? 14 or 12 cm housing your spool should be pretty good so again you'd be gaining from more timing. I've ran a truck at 21 in manitoba Canada which has very extreme winters. Although this year was a bit mild. I would suggest 18-21 depending your intended use. If it's a toy rip around truck Id go like 24 or so.

Hell, if it's a warm weather toy go 30. If you actually intend to use it though, you can easily get away with low twenties, if you plug it in.

Yes it is only a warm weather toy. So with your guys input I should put it 24-30 degrees timing? Thanks for your input!

what cone angle are your 7x.014's and I assume stock pistons?

To tell you the truth I don't really know what angle they are I bought them used and never was told. And yes they are stock Pistons.

cone angle is important in determining how much timing you can really run with stock pistons, with to much timing you will be spraying fuel out of the piston bowl, not a great thing. i would start about 23, and work my way up, see how your engine likes the higher timing, see how you like how it runs. you will loose some of the low end power the higher your timing gets. i prefer to run an adjustable timing gear, may be something you want to look into if you plan on playing with the rig.

Indeed, once you get out of the mid 20's there are... compromises.
