well..the first like 50 miles the shop does..then i start driving it..and what i do is stress the motor..like 1st gear take it to 4k rpm then 3rd so it puts strain on the motor..heard it was a good way to break in the motor..and after like 300 miles i changed the oil and start going to like 5k..and eventually work the way up..last time i waited til 800miles before i beat on it..but thats ONLY cuz an 05 vette was fucking with me and talking shit..older guy..then i beat him and he apologized hahaha..i couldnt wipe the grin off my face for a week..going from a b16 to lsvtec and beating a 400hp 05 vette..

1500 lsvtec build blown by bad builder
1400 lsvtec rebuild by good builder
beating a shit talking guy drivin a new 05 vette...priceless..
