Hey all, this is my first post here on gt40s.com and I am looking to have an RCR Gt40 MKII built for me with a 7.3 Godzilla. My reasoning for wanting the Godzilla over a Windsor block 427 is that I want a more modern engine with better reliability than a Windsor with modern 8 stack fuel injection and a dry sump oiling system. I also want something other than a coyote. I plan on doing a lot of heavy track days with this car and also potentially racing it. An engine like this was what I had in mind with maybe less power for reliability: https://www.willisengines.com/dyno-results-ndash-stage-3-ultra-street.html . Does the Godzilla sound like a good choice or does it just sound good on paper?
7.3 Godzilla in an RCR Gt40 MKII?

It sounds like you will break your transaxle!
Sure you can make big numbers but what will you use to put that power to the ground?

I plan on using the Graziano transaxle that race car replicas supplies that can withstand 1000 hp

If you haven't done so already, 'might wanna break out a ruler and put it to good use before you fill out the order form for a Godzilla. ;-) There's not much wiggle room in a MKII's engine compartment (even less in a MKI)!
Just sayin'...

My MkII home built chassis project that has a 482 CI SOHC with a Ricardo tran fits.

I'd wager your home-built chassis played no small part in that, Earl! ;-)
Sounds like an exciting project.
I’ve only built 1 car with over a thousand HP and even though the car with me in it weighed 3,000#, It was a beast and without racing slicks there was no way to put even half of the power to the ground. Yes it was cool - but simply over the top and could be a real handful to control.
The 7.3 is a great motor and a real stump puller, but I think I’d look to something that produces a more street friendly torque curve rather than 500+ LB FT just over idle speed…
edit - The street tires were DOT Drag Tires that had a section width of 18”..

Thanks for everyone's input. I do still think the Godzilla will work and with the dimensions of 28.74x27x29 inches it should fit just fine if not a little snug. In terms of horsepower I think shooting around 600-700 would be more than enough for the car because recently I did the GT40 Lemans one day experience with David Zubick of Racing Adventures and found that the 550 horsepower engine could really make that car fly! Also I do just really like the idea of putting a Godzilla in the car because back when ford was using the 427 it was originally out of the Galaxie and I would like to apply that same principle with fords more modern engine from the super duty series.
