| + | Does anybody know if these heads are exactly the same as the 1993 and 1994 and higher 4.3l V6 "Vortec" heads? | ||
| + | |||
| + | All the parameters match. The valve sizes 1.94 I vs. 1.50 E, the "ski ramp" swirl on the roof of the intake, the eccentric location of the spark plug hole. | ||
| + | |||
| + | I still have to cc the chambers but it starts to look like these heads are the same. Must be a reason that these engines produce 300 NM torque at only 2'800 rpm in stock trim. | ||
| + | |||
| + | As I'm in the middle of a build it would be great to have that confirmed. | ||
