Some of you probably know i did a swap from an 88 stock 350 to a '77 heavily modified 355 strictly because of the high nickel content in the block and the amount of hp for the price- $1535.00 for 400+ hp and 425+ ft lbs on ebay. Got the swap done headers, intake, fuel system, and all efi components hooked up and running except the knock sensor. A '77 block has no knock sensor whole so I called the local chevy dealer and none of the techs know. Also called a few machine shops and got nothin. Where the hell can you put this thing on a '77?
