thanks trueblue,,you have to look inside to be sure what engine your looking at if you really want to be sure,,you might buy a 302 car and later find its a 351!or visa versa,,the 351 had both two and four barrels,the 302 mostly two barrel, i think the 69/70 "xw"302 gt had four?holley came on the gt four barrel,motorcraft and thermoquad on the others?not really up on old ford stuff,i should be though,a factory hurst shifter came on the first "xr"gt with 289 in 67,along with stuart warner guages in the dash,i like the xr model,cept for the single circuit brakes that can be easily swapped out though.
