hey, i have a 98 coupe with a 3.8 v6 and 5 spd tranny. i want to gut it and put in a carburated 400 small block with a 700r4. i was told to order the motor mounts and brackets from an lt1 model because the block was the same now im being told that they wont bolt on to my 400?? also wondering about the gauges, will i have to keep the computer to get them to work or buy some aftermarket gauges. i have everything else pretty much covered but if theres anything else i need to know please tell me. thanks.
