you dont just bore a 400 block to 427. you put in a stroker crank with a mild overbore( probably.030"). but honestly, if youre not going all out with the motor, id say just bore it .030" over, and keep it a 406. nothing wrong with that engine.
as far as winter plans, that all depends on how the rest of this year goes. im heading to the strip on Sept. 23rd. im going to have my NX kit on my car, so if the motor blows, i" be trying to build a new motor this winter.
id also like to get a bit more bodywork done, we'll see how that goes. something else id really like to do is clear as much wiring out of my engine bay as possible. without my heatercare under my dash, i have tons of room to mount all my wiring.
an interior would be nice too i guess....
