90mm Lightning maf

not only is it one of the best choices out there, its one of the cheapest at around $80 and about $20 for the plug. I'm using it on my lil 302 and have zero complaints.

80mm will be plenty It flows much more than your engine can even breathe in, like your throttle body. But it won't hurt your straight line performance.

The LMAF is a great option, IF you are ready to custom tune the motor with a J3 chip.
This meter will provide great idle (assuming you have a good tuner), and enough airflow to split a stock 302 block.

However,
A custom tune is REQUIRED.
