Re: Run it or rebuild it?
Ah, I thought you were getting at verifying piston clearance. I will look into that though.
Here it is all disassembled. This is the third engine that I have had rebuilt/assembled by my local machine shop and all I can say is they apparently do good work. Everything has checked out really well so far. This will be the 3rd motor I have built from a bare block and the first two are still running strong (a log 2.2L TI and a 2.2L TIII). I must have done something right (thanks to you guys).

Re: Run it or rebuild it?
Anybody got the torque specs for ARP main studs handy? I talked to RPM machine shop in Sturgis and he needs the spec to line hone this block which I hope to drop off soon...
Re: Run it or rebuild it?
I haven't had any issues with the bores being out of round on the two engines I've put the main studs in. They weren't measured, though when checking the bearings on one of them later on they didn't show any unusual wear. YMMV
Re: Run it or rebuild it?
That is basically what I have heard as well Ray. It sounds as if the line hone is ideal but not absolutely necessary in most cases.
Right now I'm thinking I'll drop the Spirit R/T block off in Sturgis and then resume the Shelby Lancer project!
Tonight I'm verifying the ring gaps. According to the '91 FSM, the specs for the TIII for the "No. 1 Ring" and "No. 2 Ring" are .014"-.020". Oil control ring spec is .010"-.020".
Re: Run it or rebuild it?
I dropped the block off at RPM in Sturgis today but I'm still having trouble locating the torque spec for the ARP main studs. Anybody?
Also, do the main studs get the ARP assembly lube on both ends of the stud before installation (block side and nut side?) I'll definitely put a light coat of the stuff on the washers and nut bottoms, but I'm not sure about the block-side threads.

Installation instructions are in that link 80 ft lbs

I'm just wondering why you spend all this money to have machine shops assemble engines when you just take them apart and re-do everything anyway? :confused: lol

They were built/assembled by a local machine shop about 10 years ago before I knew how to do it myself. Plus it's just something I want to get better/faster at.
Re: Run it or rebuild it?
I picked up my TIII block this afternoon in Sturgis. The machinist (who I'm pretty sure is the owner) did it and seemed very knowledgeable and gave me some tips on installing the studs for the final time. He said he line bored the mains (not just honed) and took a little bit of material off the caps similar to resizing connecting rods. He also told me to forget the ARP instructions and install the nuts to 70 ft/lbs. I think I will follow his advice since he likely used that spec to finish it.
$200 for the main line bore, another $60 for the hot tank. A little more than I was imagining, but I'm happy that it's done. Very clean and ready for paint and assembly now.
Re: Run it or rebuild it?
Wow 70 instead of ARP recommended 80? Maybe ask more of the turbo dodge members about that one. What kind of gasket are you using, mls?
Re: Run it or rebuild it?
Last time I priced a line bore here it was $300, so you got out cheap :)

Yup, Cometic MLS headgasket (.051") with copper spray and ARP head studs and also Cometic manifold gaskets too.
Re: Run it or rebuild it?
They have the spec for a reason, we usually go higher not lower. Stick with the recommend value.
I'm with FFM, why spend all that money and redo it. I'd have run it as is, :p
Can you post pics of the piston tops please?
Do the rods have ARP's?
Only need to coat the top end of the studs, not the block side but it won't hurt.
Edit, I had these specs in the old FAQ's.

Mains studs are 65 ft/lbs
Rod bolts are 50 ft/lbs.

I dunno, I just didn't feel good about running it after sitting for 10 years being stored. I will at least feel better about it having some fresh assembly lube and the confidence that the specs are correct to the best of my ability.
I will get some pics of the tops of the Venolia and Wiseco 2.5L TIII pistons up soon. And yes, the stock TIII rods have be reconditioned with ARP rod bolts.
ARP says 80 ft/lbs; you say 65 ft/lb; the machinist says 70 ft/lbs......If the machinist finished the bore/hone with that main caps at 70, then wouldn't it be best for me to use that spec in the end?
Re: Run it or rebuild it?
Yes, if they were line honed at 70, use 70.
I got that spec in the ARP box with the main studs I bought. I've spun my TIII well up to 7500 and beaten the crap out of it as you know, never had an issue with the mains at 65.

We offer our 16-V pistons in two different dish sizes.
