My understanding is the misalignment of the lifter angle coming off the cam with the pushrod angle is a legacy of developing the LA smallblock as a quick-fix evolution of the original 318 Poly block so the V8 could be installed in the A-Body (1964) when industry intel told of the pending V8 Mustang. The late 80's/early 90's truck LA's introduced the factory hydraulic roller cam which aggravate the angle further due to the greater height of the lifter body (thus shorter pushrods). No problem in a street motor in my opinion. I'm building a 4" cranked 360 from a 1990 truck and keeping it cheap with 308 heads. Rick Ehrenberg was featuring a similar build using the TrickFlows, anticipating 500hp with cast iron exhaust manifolds. Anyone see the dyno results on that? I haven't received any Mopar Action issues since Covid. Regardless, we've all been living with the bent lifter/pushrod angle since 1964 so I'm not worried.
