If you have a completely stock 2 ton Chevy truck you may already have a splasher 235 in it. We had a '47 and it came with a 235. Ours had a vacuum two speed rear end too with dual rear wheels. Ran like a top. Did ranch work and hauled hay from 300 miles away every year until 1968 when we sold it and bought another Chevy with a 292 in it. It is still working here and dependable as ever. Get a block number and go to www.inliners.org They have a block number chart that will tell you if yours is a 216 or a 235. The 235 splasher came out in 1941.
