hi

how can you tell the difference between a high and low compression block just by looking at it pls, and is it worth trying to turbo a high comp engine?

side of the block inlet side near the sump theres a small flat machined on the side it will either say 25 6k or 25 6e
for the low comp one you want it to say 25 6k and yes you can turbo a high comp engine wont last 5 mins tho or might be good for about 4-5 psi and thats it
