I understand thanks! I guess the question I keep wondering is: is the anything I should keep in mind that might be different because the original engine looks like it was a 225, and the 360 appears to be a late seventies engine with some obvious changes. I'm on vacation this week so I'm going to be pulling more numbers off the parts to zero in on what I actually have. I understand that the casting numbers are located in a couple different locations (driver side front of the block, driver side bottom of the block) I pulled both of those already and am going to look on the oil filter side for the others. The numbers under the driver side head were hard to read and didn't make sense when I looked in the front of my year one catalog! The number below verified an LA 360 but only narrowed it down between 75-92. Also want to pull the numbers off the Holly 4bbl, not sure what the cfm is on it. It has a Weiand I take manifold (not sure what version yet). Also has exhaust manifolds off 340. No headers, but it has H pipe dual exhaust with turn downs. I like the muscle car sound of the H pipe over the crossover exhaust I'll be out in my garage all day today lol! Have a good one and thanks for all your help and advice
