yea so today i revved my car to 3 grand for a sec just to hear it pur after a new head and headgasket job that was done about a week ago. my dad heard it and flipped his shit, talking about how he spent money on it and i'm screwing the car up. He wasn't kidding either he was pissed to say the least. Can barely revving it while in park hurt?

Oh, brother, you don't even want to know, if you've got a 4hp22, then hell yeah, you could potentially ruin your transmission.

:eek: guess i wont do that anymore.. i mean its not like i do it all the time.. very seldom.. but i wont at all now.

It's just generally a bad idea to do it. Nobody wants to be that douche at a stoplight that keeps revving his engine to look cool. You've got a big boy toy now, drive it like a big boy. First things first, go tell your dad he was right, this will allow him to remain Alpha Male of the house.
