Well, that's basically what they did with the ZR1 Snake Skinner

I think there are enough ZR-1s around not to make it a sin. Besides everything would probably be reversible anyway.

Ok. I will have to google what is the AIR system and see if it's something I might want to keep.

But what would be your guess of how many lbs it would shave if all you suggested above was done? Thanks.

AIR pump

This is the pump you also have plumbing and other related parts. If you live in an area that still has emissions testing you will have to keep it.

What video do you mean? Thanks.
Those are "TURN-KEY" prices - parts and labor on YOUR LT5 motor.

The video - no biggie, it just features a video showing my stock idle ~ 510 hp LT5. Smooth, no dual mass knock or trans rattle (single mass aluminum FW + sprung hub disc).

Oh, ok. So where do I see the prices for the parts alone, for those who want to do it themselves?

I don't think I saw the video you are talking about.

Is there any thing behind the name change from ZR-1 to ZR1? Does ZR-1 even mean something actually? Thanks.

It was originally ZR1 back in 1970.
