I have a 97 that the has been built to basically be an LT4...Has the hot cam, intake and so on...Other than that the car is stock. It hasnt seen the road other than a tootle around the block to keep it running. She still runs good i must add. I want to take it in and get all the fluids changed but need some advice. What kind of oil, trans fluid and its a 6 speed if that helps, and anything else that i might need to check...thanks and cant wait to get back out there and let her shine...

 

Follow the recommendations of your Owner's manual. If you don't have a manual look for Shoebox's website. He has a link to Owner's Manual downloads.

5W-30 oil, conventional or synthetic. Dexron III ATF for the T56 6-speed.

Why not change the fluids youself? Save money and learn more about your car? Don't forget the coolant, rear axle lube, and brake fluid.

Has it been tuned for the HOT cam?

 

The motor is bored 30 over...355 now....balanced the whole 9 yards...Harry's hotrods did it here in dallas about 5 years ago....still runs like it should. i was just looking for adivce and to see if there was something new out there

 

Since it's not "stock", what oil did the engine builder recommend? He would know how he put it together.
