Nice, we ended up splitting some HX's with H's to get the clearance and other straight HX's. Sounds like your getting close.

Using a torque plate to bore/hone the block, or to check ring gap?
Cuz I got the machine work done @ Rallispec who DEF know what they're doing. But I never heard, or even thought about using one to check ring gap. But it does make perfect sense cuz it'll twist/distort the block to simulate the heads bolted on.

We used the torque plate for everything, hone/checking ring gap.

Just checked a block done by my machine shop and the specs were off. They used a torque plate to hone and fit piston ring gap, we did not have a plate. Definately on the tool wish list for my next build.

Wait, I'm confused. You said they used a torque plate, but you don't have a plate?

Correct, they used a plate. I wanted to verify their specs prior to assembling the engine. But could not as I don't have a torque plate. 1st engine, 1st time, but in the future I will have a plate.

Gotcha, no idea WTF I was confused about, seemed like a pretty straight forward comment


So when checking main bearing clearance, is it better to use old used main studs? Or new ARP's, and risk stretching them?

Did Rallispec perform a align hone on your block with your ARP main studs?

Either way, I would use your ARP studs, they pull differently than the stockers (we received different readings than stockers at stock torque, I think my buddy said that was due to the ARP lube). We did not end up using stock torque, read below.

(I wrote this in Smitty's journal too as he is using ARP main studs as well for his build )Are you using stock torque specs or ARP specs. I can't quite remember the torque of the stock bolts as the final sequence is a angle turn sequence (quite a bit lower thougher).
When we did final assembly on my 08 last summer, ARP had 70 ft. lbs on the sheet and we knew this was going to be over kill without an align hone on my block. We actually went with 58 ft lbs. at the time and picked bearing halves to get the results we wanted. The new ARP main studs instructions are rated at 60 ft lbs.

With ARP studs do you use stock torque sequence at those settings to check clearance?
