so im getting ready to fire up my first LS engine build. I put in a 11.5 compression stroker kit along with some dart heads, my question is: since its a lot more compression than normal, can i fire it up like that or let the tunning shop start it for me? thanks for your answers....

 

Id say go for it, just watch oil pressure.

 

even though im still running the stock injectors?

 

yea...

If you went to bigger injectors and didnt change anything in your tune, I doubt it would start, or if it did it would idle/run like crap.

When i did my ~11.5.1 H/C/I I drove it over to the place to get it tuned on stock injectors then added the new ones in their shop.

 

ohh ok....sounds good.....so you also thinks its safe to break in the cam like that?

 

I would be very weary about doing any kind of WOT or hard pulls until you get it tuned.. Starting it up and checking oil pressure, leaks, etc it should be fine. If it runs decent then go take it for spin.

What size cam you go with? You running milled heads and smaller gasket?

 

ok ill do that then. thanks a lot waterbug your a big help

 

oil pressure is the big thing, the little o-ring by the pump can be a PITA to get right the 1st time.

 

the o-ring?.....its the one going to the pick up screen right?

 

tube to the pump..

 

yeah i remember that one....its on....
