heres an old hot rodders trick to timing your 454 use a vacuum guage attach it to any non ported vacuum connection on the intake for an example disconnect the vacuum directly underneath the carb that goes to your vacuum assist power brakes then adjust your timing untill you have the maximum reading on your guage this may take several adjustments to allow for advance and retard once you have achieved maximum vacuum back it off about 5 inchs say...

POI Had a Banks powerpack on our 454, if you have the paperwork check for timing recomendations. If I remember correctly the timing is advanced 3-5 degrees over stock.

Is that a Classic or a Slabside?

Hi, you can set your timing the old fashion way. With a vacuum gauge connected to manifold vacumm, you want the highest reading at idle that you can get. The other way is to advance your distributor until you hear your engine gas ping under hard acceleration, then retard it just enough to stop the pinging. This method will work if you don't have a timing light or can't see the timing marks.

Not sure if I am in the right zone here..but I am new looking for insight into purchase of an Air Stream RV. Any insight into the power ratio of a 5,9 cummins on a 95 36Ft RV? I am wondering if this unit will be seriously underpowered. I check with Banks Power, and they claim they can up power a 5.9 to 259hsp, pulling a 6% grade in their test at 70mph. Any insight for the Air Stream Seach guy...cheerio..karl
