Changed the needles in my Edelbrock 750 and checked the complete truck over to drive 350 miles to the Saskatoon out door cruise weekend on Aug 23rd - 25th weekend. Will be a real cool time going with a few others from our area, they are trailering their cars, a 69 Charger, 69 Camaro SS and a recently finished 56 GM lowrider truck from our site (Dubie). Can't wait but will be some kind of gas bill with the big block.
