Good morning everybody ! Hope everything is going good on your side. I currently own a 75' Electra with a 430 in it (The original 455 have had a problem and has been replaced with a 430 before I bought the car). For the story I bought the car last autumn and drove it +5h hours on the highway to bring it home. It drank two or three pints of oil (which is no good) but rode like a charm. To make it summer ready I changed the following things : - Swapped the stock intake manifold for a EDL Performer Intake - Cleaned the Qjet - Swapped points ignition for HEI + new sparkplug wires - Installed long tube Doug's headers (the car already had a 2.5 inches exhaust system with no X or H pipe with two cherry bomb) Up to now the engine STILL drinks oil, I am guessing both valves guides and piston rings are shut since I can see blue smoke at the start up (not at every start up) and every time the engine is under load, especially going up a hill. The engine is going to be pulled out this winter so the shop I work with can tear it apart. I have a few ideas on what to do to make it a good and reliable sleeper but since I am still learning how Buick engines work, I might be wrong with some stuff and that's the reason I need your help/opinion What I had in mind as far as mods/parts was : - Oiling mods for BBB - EDL Aluminium heads to match the current intake I have - New camshafts (don't know which one and which brand) + timing chains - Not sure if I am going to change pistons, that will depend if the block has to be bored over (we'll be fixed when we are going to tear it apart) (if so, should I buy notched pistons or not?) I know TA Performance got very good parts but I have to admit I order much of my stuff on Summit since the shipping cost is much more friendly considering I live in Quebec. My main questions are : is my current setup fairly good as far as performance and reliability ? Should I systemically buy new pistons instead and keep the iron heads instead of the EDL ? I have no HP goals whatsoever, but 500 is a fairly good number imo. Discuss !
