340 actual horsepower

I bought my 340 Swinger new, and with it, the Mopar "Hustle Catalog", which recommended hi-po stuff for all the engines.

For the 340, the immediate recommendation was Holley 3310/780, Edelbrock LD 340 dual plane manifold, and Hooker under chassis headers.

I did it all including 12.5 pistons, got it down to 13.29, back then... lol
