Help! I need to know what the size of my engine is Im an hoping it is a 350 but some of my freinds say its proboly a 305 If it helps it is a 84 gmc seirra classic 2wd
Well, on SOME engines the location of the oil dip stick will suggest engine size. If it's on the driver's side it would be a 350, on the passenger side would be a 305. However, the ony true way to tell is to get the casting number off the block, which is located on the driver's side of the block on the very end of the motor on the bell housing flange. Once you have the number you can look it up at www.mortec.com or another site that I found http://www.nastyz28.com/sbchevy/sblock.html Hope this helps. Robert 74 Chevy C/10 350 c.i.d
My 87 350 has the dipstick mounted on the passenger side, the easiest way to figure it out is to get your VIN number off your dashand look that up, for example: 1GCDC14DXBD100.001 is a generic number for trucks made from 1981-87. The second D denotes the engine type. In 1984, an H stood for 305 and an L stood for 350. Hope this helps.
