then in my Head..you just Validated using the 400 block...if your going PRO-STREET....the only problem you might have and this is a MIGHT ONLY,,is cooling the motor...if you only filled to bottom of freeze plugs you are probably ok...top of the water pump holes and its too much for circulating water on the street use...whom-ever filled your block knew these blocks were weak in the webbing......so if the machine work is done i would rock-and-roll with it.....the extra CI never hurt anyone..also the 400's (406) will give you the extra TQ the 350,355,383 will not give..


for the record my wife has a 406 in her 69 camaro..2 freeze plugs 4 bolt..and it made close to 500 hp on the dyno....in a 3300lb car, all street trim, DOT ET Streets 26x10's, thru the mufflers, footbraking, with a standard choke horn holley 750 carb,...the car runs 7.40's all day long in the 1/8...whats this..11.0's or high 10.90's in the QTR ??????...and she drives it !!!!.... 8) 8) 8)
