Why Are Edelbrock Cams Unpopular

Well, in package 5 he use's a Edelbrock cam. Though I like how it respons with a larger carb. I don't remeber what pistons he used in E-mailing back and forth with him, he just generalized 9.5-1 on the web page. IIRC, and don't bank on that, *I think* it was a set of Fedral-Mougal slugs for the 9.5-1 ratio.
The KB's would slip right in that build right nice with a .3 to .5 more compresion.
A few other tricks like zero gap rings and such would boot up the torque a bit right nice.
