I am Hannes from Austria/Europe and I am a BBBIIIGGG addict of american sheet metal.
I have an 68 Impala converible that is going to be an SS427 clone some day in the future and a less worthy Buck Electra Limited from 71´that is loaded to the top. Looks like it got everything you could order that year.
I spoke to a guy from a junkyard and sent him some pictures and he told me, he saw thousends, if not 10 000 of cars in his life but only once or twice an Electra with all that options.
It is not an collectors car but my Impala would rather leave the house then my beloved highway-yacht. I just love her to the death.
Unfortunately the conditions are not as perfect so I deciced to restore the Electra from the ground.
I would like to do a little to the engine and now you enter the game.
I have an 540BBC shortblock with Dart 320 aluminum heads that was dedicated to my SS427 Impala build, but want to go with an LS3/6l80e combo now as gas is very expensive in Austria and I drive the Imp more often, the Buick is too holy to wind up 1000 of miles. Plus, both are summer-cars and the summer is short in Austria, so I want to drive in the convertible as often as possible.
So I had the idea to put the stroker BBC in the Buick, but after some research I found out the Buick 455 is something better than the BBC. More light and very powerful.
I will resell the BBC and want you to ask what to do with the 455BBB?
My target is to build a little of an Pro Touring-ish Electra, I have a new front end kit and new shocks that adjust themself depending the way you drive (they are Monroe´s, they called it "intelligent shock absorbers without electronics" that time).
I want to install an airride and 22" disc-wheels, nothing irreversible, all easy to build back exept the airride but if it is on the right height it looks stock and will improve the ride once the car should look stock again.
No I was hoping that you guys could play with your creativity on the engine.
The 71 is what? 8,0:1......8,5:1? Quite less in any eyes.
My thoughts was towards stroking (seems not to be easy on a Buick-Engine as there are NO stroker kits and only a few cranks that are horrible expensive), or low-budget turbo charging or what ever.
For sure I will go with aluminum heads by your recommendations, TA or Edelbrock (some others too?)
The idea of a big single turbo is something very likeable to me, but mileage-wise maybe not that clever. At the stop and go traffic, which is most of the traffic the car sees in the town it will be unefficient due to the low compression. A higher static compression would be more wise if I want to have an eye on the efficiency, but tell me your sight please.
I would like to see at least 500hp but low end torque will be the more important factor and the key I think.
How much power can the 455 take and what is your concept on a 455 in an Electra and please, be precise.
Thanks for your time guys :)
