I've been looking at different cams lately, and found that a lot of the parts sources I have list the same cam for the car and the truck engine.

Is the increased lift due to using the 1.6 rocker arms only?

Can I retro-fit my rocker shafts with the higher ratio rockers, or would I need to make other changes?

I've got a 1bbl 74 Valiant, that my Brother and I are converting to the GM Batch fuel injection. (For background)

I'd like to get a header that will fit my High Starter 225. What single piece headers would work on this car? No A/C

I'm toying with building my own intake runner/air box to optimize for the MAF, and Midrange. Who knows how that will work out...
