Is it a big deal to put ls6 oil pump on ls1? ive got it apart puttin cam in on stand and had someone tell me to upgrade, is it that much better?

 

It has been the same pump for quite a few years now.

 

When I did my cam I got a high flow pump and double roller timing chain while I was at it. Iff you have it apart already then upgrade. I did it because my car had 86k on it and the oil pump is a major part to keeping the car running good and did the timing chain cause it was $80 and always better to replace old stuff while you have the chance.
