First pic is a 1969 L34 SS 396 out of a 69 El Camino, it made 475HP @6000rpm. I dropped it in to my first 72 LWB C/10 and "Nasty Sally" was born,
https://www.youtube.com/watch?v=_jXx...&index=1&t=10s 350TB 4:56 Posi 12-bolt, turned 13's in the 1/4. Second pic is the current pumped up 427 (.060" over 454 block) with the 396 crank, JE forged domes, 1969 closed chamber L34 heads w/stainless valves, Clay Smith springs and solid lifter cam. The 396 crank was balanced to .08gm (dead nuts) the dynamic CR came out to 12.5:1 so 110-112 octane only. Finally got her to the track before the season closed, she turned low 12's revealing she needs a bigger carb and a higher stall.
