I had a 305E in a '65 3/4 ton,and with the combination of a 4:11 rear end,and a 2-speed hydra-Matic,I got top speed of 50 M.P.H.,and about 6 miles to the gallon. that was with tall 16.5's ! They are powerhouses,though,but if you're looking for a rebuild kit,GOOD LUCK!! I just looked in my "Kanter" catalog,and they only carry parts /complete kits,for the 1960-'72 351,and 401's,and the 1960-'74 305E's Here's a break-down of the 401.(4-7/8 Bore): Piston:$82.50,Ring Set:$580.00,Piston Pin bushing:$11.00,Main Bearing Set,(LIMITED STOCK):$175.00,Rod Bearing(std,.010-.030:$10.50,Cam Bearing Set:$65.00,Cam Gear:$40.00,Crank Gear:$35.00,Camshaft:$225.00,Push rod:$5.00,Rocker arm:$15.75,Rocker Shaft,(2 Required),$50.00,Rocker Shaft Assembly (Each,2 required),:$85.00,Valve Lifter:$11.85,Valve Spring:$4.12. You'll need to contact the company for a price on their gasket set.www.kanter.com Quite expensive ,but these engines are dependable,and will last a long time,if rebuilt correctly. Here's a '65 400 in action,during harvest. Round-trip of 200-miles,for a week or so. WELL-MAINTAINED!! Check-out the A.D. 2-ton,pulling an empty trailer), Passing while shifting into overdrive!
