I'm in the process of building the engine out of my T/A that I spun a few rod bearings. Fun fun, but I'm just wanting to share my experience as I build it. Doing a proper engine blueprint.
I've been working on it for about a year. Just buying the parts as I can afford. A picture of the rod bearing cap. You can tell that it got some heat into it. Here's a video of my buddy and I removing the engine from my car.
I was originally planning on using stock rods, but both sets I had were junk. As you can see in he pic below. So I decided to go with a set of eagle forged h-beam rods.
Started weighing the rotating assembly. Forgot to take pictures while I was
and hope to have the cam ordered Monday. Also measured the cylinder bores. Only a few other things to order!
Weighed rods and cylinder bore sizes.
Measured the bearing end on my rod set. All were within a tenth. Did the wrist pin bores and there was only 2-3 tenths of clearance. So I'm going to hone them out to 9 tenths to get the right oil clearance. Here's while I was measuring the bearing bores.
Started checking oil clearances for the rods, and they were a little larger than I was wanting. I could have ordered a few 1 under bearings to close the clearance up. But in the end I decided to order a new crank. Had to get a new reluctor wheel as the new one is a 58 tooth. For a few extra bucks and I get a little bit more piece of mind. The mains were going to be the same as well.
Got one cylinder bank most of the way done today! Had to hone 6 thousandths. Have to do a final pass to knock down the peaks from the initial pass. Got the deck height measured too. Was with in half a thousands.
Final hone is done!! All the cylinders are within two tenths and cylinder tapper as well. Got to give a big shout out to my buddy Jonathan for doing the work. I just helped where I could during. Spent about two hours cleaning once he was done.
*****! I was hoping to get away with not having to line hone the block, but I'm not so fortunate. Went through measuring the main bore housings and they were a little big. Changed the bolts since I was using the factory type TTA bolts thinking maybe they had streached. The measurements stayed the same.
