Well Mike, first of all, I have to say that ALL 41 chevys are seriously COOL. The first hot rod I have any memory of was my Dad's 41 chev coupe with a built to the hilt 270 jimmy, so the 41's hold a special place in my heart so to speak. If I had a 41 pick-up I'd go with a period correct hot rod. Bored and stroked full pressure 235, or else a 261 or one of the GMC inline sixes, fenton headers or a split manifold, 3 carbs, the whole bit, et. There are some good books on the subject, there is a wealth of good info here on the Bolt, and our good buddy Tom Langdon at Langdon's Stovebolt Motor Company can be very helpful at times. As mentioned above by Highlander, an absolutely correct restoration can be very expensive, and it would be tedious and time consuming. A period correct hot rod on the other hand gives you more room to roam with your imagination, will probably end up costing less, and in my opinion it's more fun and a whole lot cooler. Just my 29 cents worth.
