    Can the crank still be fine after wearing through babbitt layer?

    Not sure if these guys did that or not but I'll have the second shop verify it. I've called around to a bunch of different machine shops in the houston area and they were all unanimous in the opinion that it'd be HIGHLY unlikely for the crank to be fine still after 250k+ miles. Even the...

    Can the crank still be fine after wearing through babbitt layer?

    Yeah I got the E458k plasma rings to go with my L2488 forged pistons. I have a 400 grit flex-a-hone the kind with the little balls all over it that I used on a previous 351w build. I've been told by a lot of people that I should have a 400 grit finish but the guy at the machine shop insists a...

    Can the crank still be fine after wearing through babbitt layer?

    Can the crank still be fine after wearing through babbitt layer?

    Thought .003" sounded like a lot I think up to .0006" is probably the right maximum OOR allowed. .0006" would be less than the thickness of the oil film any higher and it might penetrate through. That website says I want a oil clearance of .0004"-.0015" on the rods and mains which sounds a...

    Can the crank still be fine after wearing through babbitt layer?

    That's what I was afraid of I saw a youtube video of a guy demonstrating that. He had a triangular shaped oblong-looking shaft and it measured the same no matter where he put the mic. Leaves me to wonder how you would even measure for out of round? Seen rebuild manuals that say to measure on...

    Can the crank still be fine after wearing through babbitt layer?

    Not yet they were in the middle of boring the block with torque plates when I called the other day. I'll get everything back this upcoming friday and it'll be a week or two before I can take it to the other shop. The other shop is a little more expensive but screw it they have a much nicer...

    Can the crank still be fine after wearing through babbitt layer?

    I'm not sure if he polished the crank or not I'm assuming he didn't because he gave me a list showing the costs of the various things he had to do and it wasn't on there. The wear pattern was completely through to the copper backing and was about 1/2"-3/4" wide and only over about 1/2 the width...

    Can the crank still be fine after wearing through babbitt layer?

    Also would I be able to check for out of round with just a outside mic?

    ARP 1/2" head bolt torque spec with 10w-30???

    Since I'm gonna wait should I loosen the main cap/rod bolts that I tightened up with oil and use the arp ultra torque? I'm gonna get the big bottle so I'll have enough. If I do that would I torque it to the same stock torque rating?

    ARP 1/2" head bolt torque spec with 10w-30???

    Yeah I might wait then so I don't have any doubt about the lube I'm using. I really wanted to put it together this weekend but I guess I'll wait another week. Been rebuilding this car for 2 yrs what's another week;)

    ARP 1/2" head bolt torque spec with 10w-30???

    Well I talked to my step-brother last night and he deals a lot with 4.6's and he says regular moly assembly lube should be good enough. He says it's really no different from the arp stuff and to just rub some into the threads of the bolt and tighten to 110ft/lbs. I have some crc black...

    ARP 1/2" head bolt torque spec with 10w-30???

    The 5 steps they speak of is not about the torquing of the bolt in stages, but rather they say to torque it down and then loosen it all the way and repeat 5 times. Something about the bolts needing to be put through 5 cylces to mate the threads of the the bolt and bolt hole. I just thought...

    ARP 1/2" head bolt torque spec with 10w-30???

    Hello again, I was wondering if anyone knew the torque spec for arp head bolts for a 351w? I'm using 10w-30 motor oil instead of their lube and these are the 6 point/170,000 psi hp head bolts. I searched for hours on the web but can only turn up info on the 7/16" bolts. On arps site they say...

    Summit brand piston rings top gap totally off coming in at .028!!!

    And yes I would like to thank their customer service department but whoever is charge of shipping these rings should be more attentive in a situation like this. I spent a month playing musical packages with them trying to get a matching piston ring set to no avail. I have a piston ring filer...

    Summit brand piston rings top gap totally off coming in at .028!!!

    Yeah I see that now that they are hastings rings my only beef with summit is that they didn't even bother checking the replacement sets out before sending them back to me. I can't get a pic clear enough to show it but the top hastings ring is visibly smaller than the top speed pro ring. Even...

    Summit brand piston rings top gap totally off coming in at .028!!!

    First off I didn't mangle the rings up dude I'm not a idiot. I carefully slipped it in and shoved it down gently with the piston. After I pulled the ring out and wiped it off there was no sign it had ever been installed. And secondly this is just a stock rebuild on this 351w I'm putting in my...

    pin connector cleaning help

    You mean that DeOxit stuff they have right? I bought some DeOxit d100 cleaner and DeOxit Shield on amazon but I'm going over every connector on my 95 gt. I've replaced a lot of broken factory connectors that I could find replacements for. Some of my busted main wiring harness connectors...

    pin connector cleaning help

    Just get some of this stuff from oreilly's or autozone Amazon.com: CRC QD Electrical Contact Cleaner Aerosol: Automotive. It's flammable coming straight out of the can but evaporates quickly and leaves no residue at all that could possibly ignite. Just make sure you disconnect the neg. battery...
