Who did you find to make you rods? most of the companies I talked to told me to pound sand, one of the reasons i went down the road of doing a stroker.

That is the correct rocker arm.

Dry sump.... This will be a chore. Clearly others have done this so look at/copy what they are doing; assuming they are getting it right.
 
The rockers have arrived, i weight matched them and took all the burr and imperfections away, so now they are ready to go.=), the weight diffrans was massive, 68g, probably the reason why the aluminium ones dont eat camshafts?, the aluminium weight 107.5g, steel ones 175.5g

If nothing else, the reduced weight should help make the engine more rev happy, and have less resistance at high rpm. I am going through a similar type of thing on the AMC 401 I am building. Tossed the old school 3/8 diameter stem valves and old school springs for 8mm stem LS valves and beehive springs. I think I calculated around 2 lbs of weight off the valve train.

I imagine I will have my AMC engine done well before I get my PRV engine back. But I hope to start sharing PRV stuff sooner than later
 
Rods are very close to small block Ford. I forget if Cleveland or Windsor. Get to measuring. No need for it to be a secret. They are available off the shelf as a nice H-Beam. A few machine steps and it is ready for your Frenchie six.

Alloy rocker arms don’t tear up cam lobes as the metal that rubs against the cam lobe is said to solve a ‘metals incompatibility’ issue.
 
All of my info I scribbled down is at the machine shop right now, so I apologize if I get some numbers a little off from memory.
Personally, I landed on a Nissan VQ35 rod, Was able to get a good deal from scat, and the b.e. width is only .817 which i believe is around .035 wider than the eagle 3.0 rod. I believe most Ford rods are around .830 wide, so can still easily be made to fit, but your removing in the neighborhood of .050 off the b.e. width and most likely having to narrow the bearing. I mainly went the route of the VQ35 rod because I found the bearing shell was within about .005 width of the eagle bearing shell, my goal was to try and avoid fixturing the bearings and narrowing them. We will see if my theory is correct or not. I will keep you posted on how they turn out.
Thanks guys for keeping this alive, John is a wealth of knowledge, and I think it will be cool to see a couple hardcore PRV engines running. Of course I am not ashamed to admit that Doggydoggen, your engine will run circles around mine, but I admit I am handicapping myself with the k-jet, but thats my cross to bear.
 
Programmable management is easy, reliable and will make a seat of the pants improvement in power.

K-Jet is a relic from the 1980s. We have come a long ways since.
 
Enjoy pain much?
Glutton for punishment is usually whats thrown my way. I own it, its fine. I like odd-ball vehicles. My K3500 tow pig is extensively modified, it runs with modern trucks over snoqualmie pass.
Speaking of glutton for punishment, there's a delorean and an amc amx in the garage as well... Honestly with the exception of the PRV engines i have laying all over now, the only thing i think i am missing is a Volvo. :D
