OH YEAH??? ill take another look.......why is it a "good" head????

no ya know what ..i took a look just now ...the oil has dried up...i'm 120% sure its an 8.. its clear....

5.7 why is it that those are the good ones?
Im curioius because that is the casting of the heads that are now on my 76, "frankensine 355 engine" Ive heard that they are the good ones because they have the larger valves compared to the variety of 58cc heads and Ive heard that the are more ported compared to the other castings???? Any info would be great!

ahhhhhhhhhhh i looked at the bottom of my engine on the right side of the oil pan..and to my hororr seen a 305...stamped.............damn........

I thought you already knew it was a 305.

They are better than swirl port and smaller valve heads, that's all. They can be cleaned up for better flow, but probably still won't equal World 305's.

Also, 14014418 wasn't listed on Mortec. I'd suggest another good look - a "6" can look like an "8" in a casting number.

its not even close...its an 8....its clear as hell..on both heads...i did find one "classic truck" web page with that number..but..gave no information....

My pocket manual
says they are 86 305 only castings w 1.84/1.5 valves and 59cc chambers. No power ratings.

Has Mortec let us down? https://www.thirdgen.org/messgboard/frown.gif

There were a few casting numbers from old 350's that werent on mortec either. Better email them these numbers and let em know.
