So the rebuild parts came in the other day and he was telling me of a few key parts. One is the new hypereutectic pistons with Teflon-coated skirts with a 0.020 oversize. Not really heard much about teflon coating the skirts, my honest thoughts are that the skirts see plenty of wear and tear and 70% will be torn off on first start. The rest probably won't make it 1000 miles but who knows www.mustangandfords.com
did a performance rebuild of a 302 and used those pistons, maybe they're not BAD. I really have nothing to go on thats just the picture I see in my head, maybe somewhere in the coating process they go down a few layers, dunno. Anyone know? So I also got fel-pro head bolts and am in the process of finding out which ARP rod bolts will work. These rod bolts are a little different in that they screw right into the rod cap. Usually you'll see a nut on the other end of it. Getting these in the right size is a bit of a challenge. Measuring them comes to about 1.6##" and the only ones ARP offers that may fit are 1.500 or 1.700". The obvious choice will be the 1.7'* since the ones in there are so close anyway but either way those are getting replaced, I don't care if I have to have some built for it. I got the junk scared out of me the other day when I heard about my friends rebuild. He did a simple rebuild of a little 6cyl in his truck. He reused the rod bolts which since my shop guy said he was doing I didn't think would be a bad idea. Nope, 119miles later the end cap blew off one of his pistons. His wife was driving Ms. Daisy when it happened too! Generally the rule of thumb is you can torque them 3 times before they're shot but pushing the design of this engine to (hopefully) twice its out-of-box specifications is going to need all the safety measures I can afford. The challenge now is getting a good rebuild on the trans and trying to stay semi-low on the cost. As I said before I got a deluxe rebuild kit from Trans-Go but the shop guy said he doesn't really like Trans-Go. So I told him I'd give the guy he knows that does transmissions the whole thing and he can use what he thinks is good and get what it doesn't have. He also told me he has access to higher performance parts for the trans and will put together a list and see where it leaves us. I'm trying for the $700 range but I won't be too scared going over $1200 for some decent performance in it. I know someone out there is thinking I'm crazy for going balls to the wall (some would say) with the engine and just "doing what I can" with the trans. Honestly I plan on replacing the whole damn thing with a fully built HD before it sees 50,000mi but that all depends. 50,000mi is just the cap I put on the transmission with the way I drive and the power it needs to handle. We'll see how that goes.
