Performance Engines - Tips Prior to Startup.
Before Start up double check
all connections, such as fuel system connections, electrical
connections, cooling connections, and vacuum connections.
We Recommend the use of 92 Octane fuel in all of our performance engines
except racing engines.
Use one of the following engine oils for break in: Joe Gibbs Racing
30wt, Brad Penn Racing 30wt, Valvoline Racing 30wt, Rotella T, Or use
1/2 qt of GM part number 88862586 E O S with regular 30wt engine oil.
If possible, fill the engine with coolant at the intake manifold with
the thermostat housing removed. This will aid in removing any air
pockets in the engine.
Always Prime engine prior to start up. There are many tools on the
market for priming many different types of engines. Most are reasonably
priced or you can make your own tool. What ever you choose to do, just
keep in mind that priming the engine is a MUST.
Set initial ignition timing at 10 deg and set max advance at no more
than 36 deg.
Once you fire the engine up, observe oil pressure, coolant temperature,
and listen for any odd noise. Also check for fuel, coolant, and vacuum
leaks.
The proper break in for a non Dyno tested Promar engine is as follows:
Run the engine initially for no less than 20 minute’s. Vary the RPM
between 1800 and 2300. Do not idle the engine during initial break in.
In the first 500 miles avoid excessive constant speed driving such as
highway driving. Fluctuating speed and RPM will give you the best break
in results.
Change the oil at 500 miles using same grade of oil as originally
recommended.
Normal highway driving is allowed after first oil change but you must
change oil again at 1000 miles and then every 3000 miles thereafter
using a high grade 10w 30.
For dyno tested engines skip cam break in as this was already performed
on the engine Dyno.
