A non turbo block has 1/8 inch main oil galley ports. A turbo block has 1/4 inch ports. The non turbo 7.3 engines stamped serail numbers are 509,097 and go up to 1,116,330. Anything above that is a turbo 7.3 block but wait just a minute..... The only way you can actually determine if you have a turbo engine you have to know what exhaust valves are in it and if it has the larger wrist pins at 33mm compared to the non turbo pins at 28mm. Just to mess with everyone I have a turbo engine but its serial numbers tell anyone looking at them that its a non turbo block so it really can't be called a turbo 7.3... Even when you see a turbo on any 7.3 you really don't know if its a turbo engine. You have to know whats inside to know for sure. Reading my signiture tells most everything anyone wants to know about my engine. If asked a question I will answer anything. Now don't start asking me what the hp and torque is because I have not dynoed it. May never dyno it either. It runs.. Its powerful.. It gets the job done.. Numbers are ego in my oppinion. Honestly if I had numbers they would be posted here. I have never tried to hide anything I do. I have several viedos up for all to learn from and enjoy. I try to take away the mystic of these very simple engines. At this time I'm actually having brake issues. If I hit em hard in a panic stop the rears lock up but its only for about 1/2 a second. Then the truck continues to move forwards like I have no brakes. The peddle is hard too and not near the floor either. I'm thinking its in the rabs valve and about ready to remove it. So you see I do have some things that are not correct and would like to fix the issues...
