1970 Dodge Dart 318 upgrades

The Dual energy makes no sense for a mopar- I did say the XE was the better of less desirable choices the 268 is an old Harold Berkshire lobe ca 1977
".842 lifters can handle very aggressive ramp rates"- but the same ramp rate gives more acceleration with a .904 lifter- that's what comp says
the Comp Purple Plus has the same ramps as the .842 Nostalgia Plus series and the XE-HL Mopar grinds are very similar to the .842 HFI
but on the mopar lifter you can get more area or you can run one size shorter for increased Dynamic compression
"Never give a sucker an even break" applies to chevies
Actually on low compression motors a mopar makes the most sense- high rpm can hide a chevy cam
I do not like to leave torque on the table in a "low performance" build- that's wehre it's needed the most
