I wish it had been this easy on my two.

I am going to be putting this to the test soon, have the car and the engine but not the time right now.
My 2 conversion cars were both built before much was available, but with all the time and trouble fabricating and modifying parts they both are as dependable as new cars. They both run on pump gas and get over 20mpg.

I wonder how they plan to get the Nag1 trans or 8HP trans to work in the B-Body cars? I didn't see any electronics on the Holley site that can accomplish that, am I missing something?

It's nice that they are doing this but like you said Greg, they didn't tell the whole story. Lots of issues not even mentioned in their video. I'm sure there is a lot out there now and more players manufacturing parts that was not available when I did my swap in 2014. Bouchillon Performance claimed they had all the issues worked out back then but it just wasn't so. I bought a kit from them that was for the most part usable but not all inclusive by any means. Once they had my money and I needed some support they stopped taking my calls. Thanks to getting some answers here on FBBO from a few guys it all came together nicely. I called it my "nightmare from hell" at the time but I am very happy with the end result in driveability, performance, mileage and reliability.

I think a large part of the problem that we see in this hobby is that many vendors build one test vehicle, design and manufacturer parts for that vehicle and then eventually market and sell those parts claiming that they fit this or that when in fact, they usually only fit the test vehicle or ones very similar. It is unrealistic to think that any manufacturer would or could explore every possibility within the brand but some do much better than others.

And on top of this add in manufacturers/vendors who are sourcing off shore with production facilities where no one there has any idea what the parts are supposed to fit. Sure, if they follow the drawings it should be ok but anyone who has worked in production knows that tolerances slip, tools wear, etc. and the next think you know the stuff doesn't fit/work.

I will try and post some pictures later as I need to get them off my phone but I am in process of putting a 5.7 hemi (possible twin turbo) in a 1966 Belvedere II. I have the engine sitting in the engine bay using the motor mounts from holley and I have to say it seems to fit well in there and a lot more room then I suspected. It is a truck 5.7 but the truck manifolds look like they could be run fine and the engine seems lined up well. The plan is to run a 727, for now to keep costs down, and upgrade down the road.
Also for the 8 speed control there is only one company, Sound German Automotive, that I know of that has controls so down the road I would like to switch to the 8 speed, but time will tell.

I haven't decided whose mounts I want to use or if I just want to make my own. I am having the same dilemma with putting my 426 into my 70 RR when I get back to that. I don't have a hemi K frame so I need to come up with something else.

Attached are some photos. All just set in there for mockup with jack holding up the rear but the mounts are mounted to stock v8 k frame as the car had a 318 Poly motor in it prior. I am waiting on the midplate to come as I plan to run one to hold the engine in place without a trans and I read that the width of the midplate helps space the converter enough in the 727 when running it with a gen3 hemi.

if you buy the right flex plate there is no need for spacer between block and 727 trans.

Here is that source and that is my GTX on the home page.

I started my build in 2008 and by 2013, delay thanks to THAT financial crisis, we were trying to figure this out since we were NOT able to "simply" swap over the wire harness from the donor car. It took TWO YEARS of searching and trying things before someone who was "trying" to help us finally gave me this guys info. It works awesome! Here is a link to my build thread. The issues are discussed/lamented about in detail there.

If I had to place a $1 bet, Holley is going to offer TF-8 control in the Terminator Max sooner than later.....(I hope!) Whether they go back and do the Nag1 I think is more open.

some random photos of a car 5.7 in my 69 Coronet (some may show a late model truck FMEA on it
