Almost Done With The Engine
Well after 6 months, I am almost done building my engine. Now due to funds I am at a stand still again. ugh
Only things left are: Mount Harmonic Damper Bead blast / Paint (ugly rusty) All pulleys New or pressure wash/paint with bed liner old oil pan Bead blast and clear coat intake Rebuild/Adjust Carb Due to back firing at WOT (back fires until engine catches up) (Im guessing to much fuel on secondary's) After all this then I can mount it in the frame rails and break it in with some ZDDP.

Re: Almost Done With The Engine
Don't use anything except paint on the oil pan. You don't want to keep the heat in. You want it to dissapate.
Don't forget to set your oil pick up correctly with the oil pan. Put the pan on without gaskets and set the pick up at 1/4 inch clearance. Mark the pick up tube location on the pump, remove pump and tack weld the tube to the pump. Factory didn't do it but it's good insurance. |

Re: Almost Done With The Engine
Tack weld is best. JB will delaminate and get in the pickup screen.
On the pan, I'm old school. Maybe the bed liner is the bling bling thing to do today. What are you running for a carb? |

Re: Almost Done With The Engine
Cool, Welding it is
As for the paint, I wouldn't be surprised if the liner kept the heat in. Might do some more research on this. Just running the good ol stock Q-Jet

Re: Almost Done With The Engine
I just did some research. Some say the liner doesn't stick well due to the heat changes. Some say they use it but have an external oil cooler too. You need a way to cool the oil so paint should work.
Quadrajet rebuild, eh! Some links for you. http://www.vetteprojects.com/kstyer/quadrajet.htm http://www.digitalcorvettes.com/foru...ad.php?t=88376 http://www.crankshaftcoalition.com/w...#Trouble_spots http://www.carburetor-blog.com/free-...epair-manuals/ http://www.buickpartsdirectory.com/carbs.htm Backfiring at wot is usually timing related. Not enough timing that is. What's the cam specs? |

Re: Almost Done With The Engine
Cool, greatly appreciate your help on the subject. Just tells me that I will be painting the pan. And thank you for the links, I will be reading alot before the first bolt/screw gets removed.

Re: Almost Done With The Engine
When you rebuild the quad pay particular attention to how to hook the needle clip on the float arm as shown in the crankshaft coalition link.
And I'd still like to know the cam specs? |

CAM: http://www.summitracing.com/parts/sum-1103/overview/
I know I might have some issues at some point due to so much lift on the exhaust but due to budget I had to go with what I had on the shelf. However anything is better than what it had originally. OEM Cam. yuck.

Re: Almost Done With The Engine
Good choice though!
Slight lope. Good torque. Better than stock. If you want more lift on the intake you could use 1.6 rockers. You'll need to run 14-16 degrees initial timing, another 18 in the dizzy with 10 from vac advance. Good choices, good work! |

Re: Almost Done With The Engine
Thanks much sir. I thought about 1.6's however I didn't want to take unnecessary risks right now. Maybe after I get new heads (down the road).
