i red an article about a chevy 454 being turbocharged and i was wondering if anyone has done it to a buick 455? the 454 i guess had 1,150 bhpit looked pretty cool im shure it would be hard but at the same time it would be cool if some one has heard of it being done to a 455. thanks Luke :moonu:
1,150 horse? Out of a chevy 454? Man thats weak :laugh:, I believe some guy is running something close to that out of a twin turbo v6. Patrick
Search the old posts . There are many on this topic. However the 455 block is not strong enough to do too much. Perhaps the newly cast block will permit more.
I just bought a D1X procharger and I am going to push about 1050 with it. I would go more, but the block probably won't take it. Some things I am doing to the block is roller cam bearings, block girdle, and I am making my own "secondary girdle" to add to the block. Also nitriding the crank is a good recommendation, if using a stock one, and I am using a stock one.
Its been done. One of the members here has twin turbos on his 455. As long as its well built and tuned the stock 455 can handle some boost, but the aftermarket blocks will handle a helluva lot more.
If wyou had an engine like that in a 76 electra 4 door hardtop, :Brow: would you have to add a bunch of bracing to the structure to support the added torque? Since its got no b-pillar I would think the car would twist there.
