All 302's are Windsor block. The only hitch in your getalong is that it is not a roller engine and the power output is substantially lower than a 5.0 HO. 195, I believe.
I say go for it, Iam prety sure all you need is the accessory bracket kit and a intake. The 95 block is set up for the roller cam so you might want to go ahead and do the cam swap. just remember 2 things 1 if you do the cam swap be sure to change the dist gear (steel) and 2 the 351 is 28 oz unbalance (have to use 28oz flywheel and balancer) whoops I thought you had a 351 w truck motor.
Some of the trucks were roller cam and some weren't. The manual tranny trucks weren't. The automatics were. Mine is an auto, complete with 351 firing order and mass air.
