2G torque plate?

[TheFlashDSM]

im doing a 700-800hp build im bringing my block to my machine shop.

what should i have him torque the plate to when hes honing the block?

I would think to whatever your head fasteners are going to be tq'd to.

I would also recommend using a tq plate as close to the same thickness as the cylinder head as possible.

im aware that the plate torque has to match, what im asking is what should i make that torque to when im doing my 700-800+ build!

I guess I'm not understanding your question.
If you're wondering how much to torque the plate down to, id suggest the same amount you're going to use on whatever fasteners you use. So if you get arp fasteners that spec to 95 ft/lbs, tq the plate to 95 ft/lbs.

If you use a different amount on the tq plate when honing, the cylinders will distort differently when you actually clamp the head down . Best I can tell u at this point.

yea i know to match what arp says from the box im using arp l19 studs what im asking is should i go by specs in the box or is there a higher torque i should use for the plate.... ex. 800hp someone used what arp said 110lbs and had great luck or someone used 125lb and also had great luck.... i need to know what ft/lb i should use for a 700-800+ build

Like I said. If you tq the hardware to a higher value while honing than you plan to tq your actual cylinder head down to, then your cylinder wall distortion will be different between the two. Use the same specs for the tq plate as you will for your cylinder head.

Just a heads up, any reputable machine shop will be privy to this kind of technical info and should ask you what hardware you plan on running, as well as its associated specs...
