The trap of the industrial / motorhome 318-3

caferacerx said

yup, I got one of them 318-3 premium engines in my 66 Barracuda, runs great bone stock 2 bbl,
a couple more things that are different about them are
1: the pistons are 1.658 compression height, instead of 1.741
2: the heads are only 57cc
3: they came stock with a double roller timing chain

57CC heads!!! Isn't that one of the lowest CCed heads on any small block Mopar?? My '69 318 Barracuda had 69CC heads....and that's pretty low. If you plug off the water jacket and used them on a 318 or 273 you'd have some pretty high compression, especially with the old high compression height pistons of the late 60s. My 318 was like 9.1:1 from the factory with 69 CC heads.
Very Interesting?????:steering:
