318 LA build log
Alright, part two.
My experience with engine performance is mostly for stock factory engines, so I pretty much just fix stuff that is not performing like it normally should in a normal factory daily driver. I've done the some form of easy basic hotroding before to my own junk and some tweaking to my daily drivers. So I figured if I can hotrod a Ferd, then I can hotrod a Mopar. Lol, we will see about that in the future.
While the block was still at the machine shop, I got the heads back and ready to port. My porting experience is not much, really just porting an intake manifold a little bit in the past is my experience. It was time to study. I've read multiple articles, watched multiple videos and read posts on the forums all for the diy head porting. I'm not doing anything crazy, but I need to work with what I got, which are stock 675 casting heads with 3 angle cut seats.
I took my time, just doing a simple clean up first removing any imperfections, then took care of the other inefficiencies, did a lot of blending and gasket matched the intake port. I did not do any polishing on the exhaust, just a rough cut and I think it should be fine as it is better than before because these stock ports are terrible with casting slag and weird sharp, jagged, ugly molding imperfections.
These photos were taken early, since then I have done a little more work to the heads.
Assembling the bottom end, and I was tempted to flip the pistons backwards, but I did not. I checked the ring gaps and positioned them in the positions stated by the manual. Also, I put the rings on by hand with a small pick. So no, I did not buy the stupid piston ring tool to put the rings on, although it might be nice to have.
That timing chain you see in the photo was not going to work because the cankshaft had been moved up when the block was align honed, so I had to buy a timing set for a .0010 crank offset. Cloyes is the brand I bought and it fits perfect.
