| I can find out today if he still has it but my friend has a Sunset 615 9 degree engine for 22500. It should easily do what you’re looking for.

Rusty, I understand what point your trying to make! But unless your gonna build an all out TD/TS type motor with dual carbs etc , etc, (not your typical bracket motor) you will not see any difference on the time slip between these two combos due to the weight differences. In addition, the newer 20 degree stuff now has 2.45" intake valves which will further close the gap in power between the too. Comparing the two motors, the 20 degree motor is 25 lbs lighter, has a better valve train and is cheaper to build. We do not race these combo's on the dyno. |

| So the 20* heads have better rocker geometry and pushrod angles than the Big Cheif. How do they compare to standard 23* heads on valve train geometry? https://postimg.cc/gallery/np3zpruo/"Dunning-Kruger Effect" -a type of Cognitive bias where people with little expertise or ability assume they have superior expertise or ability. This overestimation occurs as a result of the fact that they do not have enough knowledge to know they don't have enough knowledge. Before you argue with someone ask yourself, "Is this person mentally mature enough to grasp the concept of a different perspective?" If not there is no point to argue. 4X NE2 CHAMPION. 2020 TDRA NE2 Champion |

point taken but my thought was on a new build add some cubes,and if doing that then the sr 20 may not be best option.just an opinion for something to think about.
