Blueprint vs ATK Engines
I'm looking at these two engines for my 64 stepside. Slight differences but one (ATK) has a 4 bolt mains and the other (Blueprint) has 2 bolt mains. Heads are a bit different. I am using an 11" brake booster and am concerned about vacuum so I am leaning toward ATK. Both have roller lifters, vortec heads, one piece rear mains and can use a mechanical fuel pump. Blueprint says they dyno theirs. ATK does not however. This could be an issue also, since now I'm reading feedback from other forums less favorable to ATK.
Whats your take? 1. http://www.high-performance-engines....0hp-p/hp32.htm 2. https://blueprintengines.com/collect...lock-bp3503ct1
