No! The 70 series direction injection heads have an EXTRA bolt that hold the heads to the block. The 1270 direct injection engine is the way to go. It will require a little sheet metal work since the 70 series engines have cross flow heads. Far greater horsepower potential from 70 series.

Heres what I got Rodger. I have a 1030 that just sits in our shed and never gets used. I have access to a 451 out of a 1270 or a 504 out of a 2670. Both these blocks would be legal in the club I would like to pull, but one class has a 466 limit and the other has a 650 cubic inch limit. I don't want to bore and stroke, so would I be better off going 451 for the 466 class, or running a 504 in the 650 class. I am leaning towards the 451, but don't know which to do. I can run P pump, and TO4 or 3lm turbo. What do you think?? I have seen you have some experience by reading back in the archives.

 70 series 451 would be my choice in reply to casepuller22, 11-27-2007 17:55:47  
It really depends on your budget. A stroker crank in a 504 can be expensive to get close to the 650 CID class limit. The 451 is right at the top of the 466 CID class limit already. There is little to do beyond the injection pump, bigger fuel injection lines, bigger injectors, and some turbo work. My son pulls a 1090 Case pro-stock very successfully. If you want more details, I'll pick his brain for you.
