Mech Fuel Pump Drag Racing 318

I would certainly try one. I think without a return it would be enough. Might be enough with one, never know till you try it.
There does come a time, but his stock block 318 with 302 heads, 625 carb and his cam isn't the time of demand. Certainly nothing wrong with upgrading it, but at his build he won't "need" it. I've had more motor and used the stock fuel pump with factory 5/16 fuel line without issue. Many times in fact.
