That way all of our pulls are compared under the same conditions. Other shops may post their numbers on heat-soaked motors for which heat-soak can account for a 20-30 rw hp difference.

how long do you let the motor warm up before making a run?

probably ~$60.00 or so for parts. dont know yet. but for just about every other GM v-8 they run around 30 bucks or so each. as for install... a case of beer, a pair of jack stands and chocks, a good set of tools and a jack, plus a few hours to swap them out.
a shop would probably charge around $150-400.00 to do it. and thats exaggerated on both ends as I do most of my work myself.
