Look at your harmonic balancer the 1 on the 350 is bigger than the 1 on the 327.
Set the motor to TDC, pull the #1 spark plug, put a small wooden dowl rod in the cylinder, rotate the engine and measure the stroke. 3.25" = 327, 3.48" = 350
If there is no sticker present, there is no way unless you take it apart
Very hard to tell without pulling a head and measuring the stroke, but there are some signs that might help. If the factory intake has an oil filler tube and there are no bolt holes in the ends of the heads, it's probably a 327.
Locate and copy the engine numbers on the machined pad on the front of the engine just below the passengers side cylinder head. Re-post your findings and we will tell you what you have.
BETWEEN a CHEVY 350 AND WHAT? Ask A question that makes sense !
no
How can I identify if my engine is a 350 or 327? Engine block casting # 3970010 Vin stamped code 18l611487 thnaks, Julio Zamago 3970010 shows up on both 1968 327's and 1969-79 350's could be either originally. without disassembly no way to really know for sure.
No such thing as a 350 big block.
easiest method is to pull the head and measuure the bore and check with the local machinist
327
yes just get head gaskets for the 350 not the 327
a 350 or 327 that is the question. A 350 or a 327
