Are the Bolt Patterns on 350's the same? Did they change from year to year? I have an older block from the 70's and someone offerd to sell me Heads off a LS1 and I was just wondering if they would work?
NO!!!!!! LS-1 heads are completely different!!!!!! LT-1's are close but the heads set at a different angle..so you need to go with 92' and down heads....
