Why is the Gen 7 496 such a bad platform to build

Larry has been great to deal with, and I am impressed with what I have bought. There is nothing magical here just the same recipe that makes power on every other big block. I will say the heads look very, very nice. The cam would appear to be ground by cam motion, and I like what I saw there. It's hard to tell how much was done to the intake, but what I can see looks to be done nicely. An Accufab 90mm throttle body is about the only obvious thing that lets you know the motor isn't stock, you can hardly see the heads under everything.
I only had one hitch in this whole project, and that is the front crossover pipe. With the thinner head gaskets the bolt holes just won't quite line up. I ended up opening the bolt holes up to 1/2 inch to get things copacetic. Other than that everything fit perfect, lined up right, and went together properly. I am waiting on my Rinda to get here to properly dial in the bypass hole in the throttle body and set the TPS properly. It certainly sounds healthier than a stock 496 HO, I am very much looking forward to the next phase when I can really put some cam to it and a nice exhaust on it. I set the fuel pressure, hit the starter, and it fired up nearly instantly. The only gaskets I replaced were the exhaust gaskets and the intake gaskets, and I could have probably reused them if I wanted to, but they seemed iffy so I replaced them. The only thing I need to find now is a flame arrester to fit this throttle body, the stock one is way too small.

Congrats, it sounds much healthier than the stock HO cam. Wait till you mod the risers. It will even get better. Too bad winter is fast approaching. Any plans on a late fall test run?

You do not mess around Matt! I don't blame you, I'm the same way when building my previous engines.

It's just what I was told when I ran it by a lot of people. It wasn't cheap driving to South Tennessee to pick up the 525 for $20,000 and then I had to have the exhaust tips relocated. I just really wanted the 525 but Donzi did not offer it in a 22 Classic except for a couple of one offs.

I never thought you were beating up on me, I dig your Donzi, and have watched a couple of videos of that 525 barking on youtube. Truth is, if I had only one motor I probably would have bought a 525, but I have twins, and I just couldn't swing the coin to buy two used 525's and refresh them.

Now I am depending on other people, and that is disappointing.
Keep up the good work!
