the motor only has 54k? give or take so im hoping to be ok on leaks... my budget has been killed... wanted to do LIM gaskets as well but cant right now... i have spent way too much money on this car in the past few months. i just hope everything goes as planned for tomorrow... completely furnished shop with lift, air, and every tool u can think of. its a 97 riviera motor goin in... any external parts that i need to swap off old motor? should i put in the 605's or exchange for 104's going to a 3.4 when i have extra money to spend... may be awhile before i do that.
