high performance 283
 
I have a 1950 chevy truck that I converted to 4x4 .I installed a rebuilt 1957 high performance 283 . To the best of my knowledge this motor is stock except for a set of new 305 heads that I installed as to have accesory holes and an aluminum intake with cast iron exaust manifolds and a holly 600 cfm carb that is still jetted for the 383 stroker that it came off of . I have yet to tune in this 283 . This little motor pulls my truck through the mud like a freight train . The local dealership can not tell me which version 283 that I have but I do know that there were several versions made ranging from 283 to 312 hp . Can anyone help me to identify which version of the 283 I have ? Please email me at stevedfarmer@juno.com

283s came with either flattop or poptop pistons when you had the heads off you should have noticed them and know which ones they are flattops will give aprox 9.0 and poptop are 11.0 with the stock heads(58cc) 305 heads vary from 58cc to 62cc depending which heads you have other things are different cams and intake systems there were hydro cams and solid cams there were 2bbls 4bbls dual 4bbls and fuel injection in 57 each in different combos to make all the performance variants so it's hard to say which engine you have and the being rebuilt is another factor but I can say the 283 is the most durable engine ever built and will probably handle anything you can do to it. we have one we are building now
