I recently purchased a used 302 to rebuild and put in my 88 GT, the seller told me it was out of a 89 GT, however I am having doubts as I look deeper into it. It is a Mass Air motor, the Casting Code on it (by starter) is 32
E7TE
CA

there is a partial VIN stamped on the back side of block above the flywheel: JX701769

Anyone have any insight on determining what year engine this is and if it is actually out of a Fox Body or a Truck? I didn't pay too much for it but its killing me not knowing, My car still has the stock 302/speed dens motor in it (106k) with zero perf mods to it, been sitting in my Garage since 04 when I deployed. finally have some $ saved to turn it into a decent street car, Id like to get down to low 13's as economical as possible, andy suggestions on proven set ups is greatly appreciated.

thanks guys
Ryan

In response to your first question - the E7TE block was used for every 5.0L engine made for several years. So, while roller-capable, it could be built in every version offered. Most versions were not roller. One of the exceptions was the HO in the Mustang, Lincoln MkVII and some rare T-Birds. There is no trustworthy way to externally tell which version it is - especially after 25 years of possible changes.

My suggestion is to remove a valve cover, and look down past a pushrod (or remove a rocker and pushrod to see better) to look for roller lifter retainers. If you can not see the tell-tale fingers of a 'dog bone' lifter retainer on each side of the lifter - it's not a roller.

On the other hand, one up-side to a 5.0 is that they are basically all the same with minor variations with the same rods, same crank, etc. So, if you have a truck flat-tappet engine, you can pull the flat cam and install a roller, etc. If you are looking to build-up your engine anyway, this will generally mean you have no big disadvantage if it's not an HO. Even if using high-stress nitrous to hit your 13's, cast non-HO pistons will take the abuse if set-up properly. If you were looking for 10's on laughing gas, that would be a different story. HTH
