68 GT350 Engine Choice

[CalSpecial68]

Looks to have the heads and exhaust manifolds for an automatic (non-smog).

I will be picking up a 68 4spd J Code drivetrain (smog heads and exhaust manifolds) from a Metuchen built Mustang.  I have no need but couldn't let the parts go in the dumpster.  I will post what I get and make them available.   

Your a good man Joe.

Thank you all for the sound advice; what a great place to get answers. I have decided to compromise and go the date correct approach on drivetrain components. A reputable local Ford engine builder (JBA San Diego) claims easy 325-350 hp with a stroker kit, head massage and cam. Certainly enough power to have some fun with.

One last question, in searching for a block and top loader, how far back from the build date should I look?

My 68 was a late December '67 casting and a Valentine's Day Ford build. In my case, 5 to 6 weeks.

The transmission I never paid attention to.

Info for my GT350s

4 spd built 5/20 - engine casting 6 weeks earlier  - assembled ~2 weeks earlier
Automatic built 6/3 - engine casting 7+ weeks earlier - assembled ~3 weeks earlier

Cast date is the same for both but different assembly dates

Good hunting

Got it. Saw the post above with a listing, same one on eBay thats 12/30/67; guessing that's too early so I will keep looking.
