Back in our January issue, we built our own version of the L89 big-block 427 using all aftermarket components. Our rev-happy Rat combo used a Dart Big M block, Dart 275cc Pro 1 heads, Eagle crank and rods, JE pistons, Weiand dual-plane intake, Holley 750 HP carb, and a Comp valvetrain.Back in our January issue, we built our own version of the L89 big-block 427 using all aftermarket components.
