Who would have thought that a torque plate could be pretty? That's one fine looking slab of aluminum!

Barry, thanks for the kind words. i have the same problem trying to get decent pictures of those things. i solved that problem by having some of them hard anodized in different colors. the black has been very popular here locally but red and blue also look great, especially after they're engraved. the hard anodizing makes clean up easier and helps to eliminate scratches too. sadly i don't have any pictures of those right now i could post. when i do i'll be sure to post them though. we'll be making runs of the bigblock, smallblock and gen 3 hemi's again very soon. we sold out of every one of those in very short order twice now. i've been getting a lot of requests locally for the GM LS motors and even a few from Mopar guys. it's always nice to get feedback, especially from the owner AND his machinist.

Are torque plates suppose to mimic a cylinder head. What I'm trying to ask is that the head bolts are of different length because of the thickness of the cylinder head. Do the torque plates need to mimic this.

I thought with bling like that only thing you could do with it is put it on a gold chain and hang it around you neck

Matt, the torque plate should mimic the distortion of the cylinder walls as closely as possible. the depth of the faster in the block does influence amount of distortion, that's the reason the bolt holes are countersunk into our torque plates.
i recently test a R-3 block to measure distortion and found .0016-.0017 near the top of the cylinder after bolting on a pair of edelbrock heads. i removed the heads and bolted the torque plate on and the distortion was again .0016-.0017
the use of a torque plate undoubtedly results in round cylinders during the honing process and results in much improved ring seal. better seal, more horsepower.
With the plate bolted on, do you hone with or without the same style head gasket to be used in final assembly? I've seen some manufacturers recommend "not" using a gasket for honing, which I can't imagine why, so I've always told my engine builders to use a gasket.

74-440Charger: Well, since you're in Florida, just try to see if you can have "Performance Only" do the machining  I'm sure you'll be happy. Ran

the gasket facilitates the plate and block to move independently from each other, so i highly recommend it's use. i do prefer to use the same bore size gasket as well as the same type that will be run whenever possible.
stacking washers under a bolt doesn't even come close to what a proper torque plate does. i've tested that theory on a number of blocks and it simply doesn't work. I'd probably look for a different shop if i were you.

Are the plates used in the boring,honing or both operations? "Machine shops" around here don't/won't use plates, not even if I buy it. They say all you need to do is "torque down the bolts under a stack of washers, if I want to go to the trouble". I am still looking for a machine shop!
and keep looking untill you find one that won't do it without the plate and Performance Only come's to my mind, since he seem's to be in your part of the country.

Just as a note way back in time (1992) my machinist (new to me then) talked me into going from .040 over to .060 over so we could smooth out my bores from not having a torque plate. He had one so I went in after the motor was bored and he showed me how nice and round the cylinders were. then he bolted on the torque plate and he showed me how much that pushed the cylinders out of round! Then showed me how they now honed out straight. he too wants the head gasket you will be using nice I went bigger bore head gasket two years ago so they are the ones 1105 I'll be using so I have used ones to use!
So the only change I made was the + 4 cubic inches and we went up .5 in compression 10 to 1s to 10.5 (or standard 10 to 1's to 10.5 six barrel pistons) same cam heads and all and it ran at least .55 better all the time so I was sold! So if you give .15 to .2 to the little raise in compression and cubes the .4 to .35 was from better sealing bores!!!
Since Dan's looked so pretty and I could not talk him into boring his plate out from 4.380 to the 4.5+ I need now I bit the bullet for a real nice piece!!
