    Well, I might have been bitten by the V8 bug recently. Any issues with the 1985 302 from a Gt Mustang? Another Ford faithful I know has one sitting around. It might be nice to have Efi......

    The 85 blocks are lightweights. Enough so that Ford added another 4-6 pounds more iron into the 86-2001 blocks. Might be an issue if you decide to stroke it or rev repeatedly it over 6 grand. The heads are nothing to write home about either. Ford went off in anther direction with heads after 85.

    I'm definitely not building it up to race it or anything. I don't really forsee getting up in the 6k range either. What is the aftermarket selection like for these?

    85 motor is defenatly a little different animal with some nice goodies inside. Completely FLAT forged pistons. Great for compression with other heads than the E5 heads, bad for cams due to no valve relief pockets.

    Now even running mild cams and and say an E7 head your more than likely going to run into PTV clearance issues.

    There is plenty of room for valve reliefs in the piston, though if your plan on running different heads on it.

    The 85 motor does have valve reliefs. It was the 86 motors that didn't, due to their use with the E6SE heads.

    Isn't the 85 motor still a flat tappet cam?


    Never-mind, mustang got the roller first.

    The Automatic trans GT's had flat tappets in 85. Rollers in the Manual cars.

    It's nice that the 85 Roller motor still had the mechanical fuel pump :) So if you're not doing EFI it saves you some effort and money.

    I owned an 85 GT 5-Speed. Fast (For its day) and fun.
