I am in need of the cam profile stats for the solid lifter, 283 c.i., 270 h.p. motor. I am building up a motor using a 283 block, to install in my 1961 Vette. Any help would be greatly appreciated.......Thx Phil

Re: 283 Duntov cam stats
The seat to seat timing specs are 35-72/76-31; gross lobe lift (includes the ramps) is .2625"/.2665".
I highly recommend the LT-1 cam for all mechanical lifter engine restorations. It will make more torque/power from off idle to redline than the Duntov and has very similar idle characteristics, so it is not detectable on PVs.
