originally LA 318 4bbl Engine??

About 2/3rds as strong as a late 60's 2bbl 210HP truck motor.....................

I have driven/had/parted/swapped a couple of them..... They rev higher, but I think the older 2bbl would outrun it spinning 1000RPM less.

Just my opinion.


Now, change the cam some, give it a mill, maybe some piston, and then you got a cast iron runner.
