Aluminum heads... polishing and porosity...

pictures as always of every step in the process would be great
 
I am terrible about that but Ill try to snap as many as I can. the exciting bit the balancing will be done way out in tokyo so I wont even get to see that part.
 
What is the connecting Rod Center to Center Length of your Lotus engine ?
I am finding online its 4.800" or 4.826" .
Crank stroke is 3.000".
Bore size is 3.750".

Did the math and Rod To Stroke Ratio R/S is 1.60 :1.

Seeing fairly high cylinder wall side loading.
Pontiac 455 is 1.57:1.

Skimpy nothing pistons cut down will likely fail fast.

Now this is a headgasket.
 
Man that is Low Deck Height Engine the Lotus.

Reminds me of a Ford 302.
Ford 302 appears crap.
My Bud Ed has a Ford Motorsport 302 block rated for 2000 hp.
pushing 900-925 hp now.
 
3 piece motor... Mainbearing plate is cast aluminum. then the pan. I want to dry sump it as the bottom of the studs would be the bottom of the motor.
 
I forgot to get the sensors off the audi I think... Sucks because I know they are not cheap. today I am going in a totally new direction while I wait for the holiday to be over. Tomorrow thank god... Then this crank n stuff can go out. Fiberglass is all here so I am going to lay up the mold for my carbon rear hatch. Also I am thinking about making a new thread on that... I may just throw everything in the intro thread.
 
I did allot of research on composite parts. Are you going to vacuum bag or prepreg your carbon fiber. you could do pre preg but would need a huge oven to cure. I really wanted to get into that but not enough time in my day with the little guy around. Not old enough yet to have him help and understand the health consequence of not following the proper safety procedures.
 
I am going to bag it. I did a gastank with wet sand as a weight and it worked ok except I didnt use peel ply. This will be my first bagged part. I am terrified that I didnt do the gelcoat and parts of my layup right. All firsts as the previous times I thougth gelcoat was thickened resin with color. ... So I always did glass on glass. My parts sucked.... Well see how this goes in the morning my time. In 8 hours I am going to try to demold it. 12 hours with all the catalyst I put in plus the fact that when I checked it two hours ago it was half baked up. Also I am going to be using heat to help along the process. My resin will be about 100*F and I plan on enclosing the space around the part and using a heater trying to hit 140*F as thats what a booth hits I think. Resin is very similar to paint and the heat helps a ton. Best example is the mold I made for said gastank vs the carbonfiber dash parts I put in my oven to post cure at 160*C My mold ripped on parting of the carbon fiber but my carbonfiber dash got sat on and only spidered a bit with the same resin. only difference was the heat. Porosity is also cut down a lot with hot resin and a heat source. I made a fiber switch cover with just two layers and man that part is strong. Too bad it looks like crap. I didnt have a die grinder at the time so I had to cut everything at that magic time and its easy to drag a fiber away if the blade gets dull.

This post is long because I am about to go to bed. But my last thing is dude. It took me all day to mess up this hatch. I think itll still be the best part I made but prep and watching WJP004's channel helped me a lot! The guy is great at glass.
