Patrick - Thanks for the info - I really do appreciate input like this. I've been messing with these LTs for about six years now and startred off with an early LT1, and basically built up to a reasonable LT4 street set up, a little here and there at a time. I see you're in SW Minnesnowta - are you in the Pipestone area? I actually grew up about an hour south of Minneapolis, been here in Texas for twenty years now. I am going to look into the 210s closely. I wasn't expecting to able to get the lift and flow numbers, so I went a little light on my cam lift to stay out of coil bind running 1.6s, figuring .600 would be about it. Anyway, I now know that 1.7 is possible and may well be likely. I will let you know what I find out as I go - Thanks again for your input! Frank
