just wanted to update this thread. as you all know the block recracked and i was miffed. so i figured i had nothing to loose at this point and droped the oil pan and took my wirefeed welder to it. 16 tractor hours later and its still running. seeps a small amount of oil but i can live with that. i have to keep the rpms at 1000 to keep the oil light off but its working fine. would still be interested in seeing some pictures of a subframe on a tc30 so that when i do replace the block i might be able to up grade. in the mean time im working on the letter idea and have backed off any negitave comments for the time being. mike
