I experienced great results with Advanced Plating, Nashville,TN.

Where's the "like" button?

 Facts made very apparent the last few days!

I did several OEM 427 blocks in the distant past. Although the material used was called a "machine grout" and was very similar to the Moroso product, mine actually contained particles of cast iron. I used tap water and did the mixing (50% of dry product/side) in a five gallon bucket and poured only one side of the block while permitting it to harden for 12 hours before proceeding with the remaining side. It seems critical to get the block deck level in both planes and it certainly helps to have some method of "vibrating" the side of the block you are working on to assure there are no air pockets. I used a automotive pneumatic hammer by fabricating an aluminum slug, approximately 3"dia x 2"thick center-drilled 1"deep, to receive a cut-down chisel shaft that fit the hammer receiver. I don't have an answer to your question re.cylinder rust: if you mean external to the cast cylinder, I don't know as I have never removed the grout from any block I've filled. I DO NOT agree that you can fill a block and be confident that everything will be round and true. The method I employed involved pouring one side, hammering out the air followed by immediately installing a head gasket plus torque plate and torque to spec.. I always allowed at least five days curing time before honing to desired finish and size; obviously, this method is best if you have access to two honing plates. You will need to have everything organized so that, once you begin the mixing process, you can proceed as expeditiously as possible; curing begins rather quickly, depending on ambient conditions. Good luck.

I installed a complete set on a Genesis (cast caps) in 2012. The only issue I had was after fitting the caps in the bulkheads, align boring and align honing when completing final assembly the rear main cap would not seat in the block. After much fiddling I determined the seal groove was not cut sufficiently deep. I called Program Engr. and they advised me to return the cap. Two weeks later the cap was returned to me, without comment or explanation, but did installed as expected. I called Program Engr. and was told "they just messed up on the final depth cut". There was no charge but that doesn't exactly inspire confidence in their product. Pay attention to Program Engr. interference recommendation at the parting face in the bulkhead.

Thank you very much for considering us fellow FE-ers and sharing the discount information. I have a couple of race-only collectors (never coated) that I want try for evaluating a four-into-one vs. merged design. There is an upcoming dyno day scheduled so my plan is the have these coated just in case they show promise, they are ready to go.

Buyer beware!
DO NOT...I repeat, do not, give any member of the Dove families any form of recognized payment for ANYTHING that you cannot or have not examined closely prior to an immediate exchange (absolutely no future delivery). I'm embarrassed to admit that I posted the requested $4000 for two sets of custom cast iron HiRiser castings with a promised delivery of 30 to 45 days almost three years ago and have received nothing but silence from Dove Engineering since they received the cash. IMHO, it is a dead business that continues to produce income form whomever they can scam into "donating" money to perpetuate the myth that they are still a viable source of FE hardware. It is a true shame that a business with so much honest potential has fallen to such depths of outright thievery and deception.

Incidentally, I have a new, in the boxes, untouched, pair of Dove aluminum HiRiser "PIE" heads that are ready for assembly if anyone is interested.
