5.7 GSIPEFS Timing??

[Lubak572]

Does this TBI motor have to be timed every time distributor is pulled out? Had heads reconditioned, I marked distributor when pulled. Put motor back in on #1 TDC can't get to run more than 30 seconds. It has to be close, loosened distributor bolt and have been turning dizzy a little. What a PITA! Any ideas? Thanks, shops are 5 weeks out trying to salvage season.

So what method to time it is used? I have seen both, using a rinda to put in base timing mode, on warmed up motor at 1000rpm or using the the timing shunt plugged i to the dizzy?

Was this 2 different things?
Marked Dizzy and pulled
Then rotated motor to TDC

Get a timing light. Turn engine over by hand til #1 cylinder on TDC on compression stroke. Put distributor in with rotor pointed toward number 1 cylinder. Make sure distributor is fully seated and engaging oil pump shaft. Put distributor cap on and replace plug wires in proper order starting with #1 at the spot where the rotor is pointing. Use the timing light when running to check timing

Got it running, turns out when I was installing motor my foot pushed in the retaining clip for the high pressure fuel pump when pushing that corner of motor back to clear deck. Started and runs fines, used rinda to put in base timing mode and locker it down.

Now just have to change impellor again before launching. Ran hot on muffs for about 30 seconds-set engine overheat telltale on. Im thinking from 100 foot garden hose- less than ideal water pressure???
