Winterization of an LT1 - Checklist

[mikeg205]

the LT1 is a roller engine

Cool - wasn't sure...was looking it up and found flat tapped on '94s - would still run VR1 Synthetic/Royal Purple

I had a hard time just finding 20W50. Only brand I could find was valvoline. I was hoping for a choice or two. Maybe Mobil1. This was just this past spring. Maybe this fall I will find a better selection.

i would run good 10w30 on an LT1 the bearing clearances do not warrant 50W oil

I would recommend VR1 Synthetic 20w50 or Royal Purple HPS 20w50. 1996 I believe still a flat tappet engine.

Well.. first time winterization of an LT1. I have read tons of posts and modified Eastie's (JimN?) checklist and supply list to be specific to the LT1. I have chosen antifreeze vs dry block as it seems a bit more fool proof for noobies. I have also re-orderd them a bit so you can go right down the list in order. So... have a look and let me know what you think.

Well.. first time winterization of an LT1. I have read tons of posts and modified Eastie's (JimN?) checklist and supply list to be specific to the LT1. I have chosen to drain the block, fill with antifreeze and dry block again as it seems a bit more fool proof for noobies and meets all concerns.
