| Eww.. nasty hard dirt inside the engine. Try to blow all that crap out without getting it down in the pan if you can. Once you have that clean pour a few gallons of diesel through and drain it. .Trying to rinse out any garbage that might have made it into the pan. |

| No.. i think only vettes got roller rockers in any of their motors. Not sure bout LS stuff. Roller motor just means roller lifters.. the most important part. |

ok so when i lift up my motor with a hoist i use an engine leveler that bolts to where the intake manifold bolts onto, should i wait until after the motor is in the car to install the manifold because i have to remove four of the bolts to put the leveler on? or should i just go ahead and put manifold on?
and should i find another place to mount my coil? considering everytime i need to adjust timing i have to unbolt the coil bracket which is bolted down with one of the intake manifold bolts
im just thinkin that its probably not a good idea to undo the bolts but who knows maybe the other 8 bolts are enough to keep it sealed while i get it in the car and adjust timing _________________

You can undo the 4 bolts from the intake to install the motor no problem. Just make sure you torque the intake down properly with all 12 first. Then use longer bolts for the leveler. I like to have the intake on if I can because it helps keep debris from entering the motor. My HSR however, I put on after the motor is in simply because of how tall it is and it's installed as a unit with the injectors already on.
You can move your coil anywhere you want. _________________ A redline a day keeps the carbon away! |

You can get some beveled washers from Tacoma Screw for ~$1.5/pc. I did that when I put my HSR on. You have newer heads and older manifold, correct? IIRC it's something like 15* bevel? It's off by a degree or two but I never had any issues in the few years I had my HSR on.
Or are you going the opposite direction? Old heads and newer manifold? I can never remember which had which. _________________

as paul said.. just elongate the center intake holes on your TPI manifold. with proper gasket and some teflon sealant around the intake bolts, should be no issue. _________________
