I’ll finish it and race it, but right now I’m sidetracked with my turbo LS pinto wagon, and my turbo LS S1-0

Looking back I think having a wagon would have been better, but at the time my Runabout was the best car at a good price. No LS power though.

I look forward to seeing how the GX500 turns out too.

The ford purists would like yours a lot more than they like mine.
I find it comical how angry they get over how I’m spending my money on my car.

It has Chevy metric calipers on the front though. ;)

I used to be a Ford purist and that's partly why I went with the 2.3T, but am now more pragmatic. If the end goal can't be done realistically with all-Ford parts, I don't worry about it anymore. If the 2.3T scatters for some reason, I'll probably go with something Toyota. Heck, I thought about putting a Toyota 1UZ-FE (Lexus 4.0L V8) in my '68 Mustang. Even has the same firing order as early Ford smallblocks.

And just like that I have a 96mm bore GX390.
With the 69mm stroke crank it works out to be 500.13cc.
Now I’m just waiting on my new reamers to show up so that I can mock it all up with a stock rod so I can get an idea of what to order for rod length.View attachment 130257

(96mm x 69mm) 499.44cc. The GX390 Case Max Bore is 100mm with a Sleeve. If you Nikasil it, you can go Bigger.

The Biggest Single I have seen is (100mm x 86.5mm) 679.37cc. The Vegas Cart 625 is (96mm x 86.5mm) 626.11cc. Stock 23hp@3600rpm.

I think 500 will be fine for the short tracks I race on. I’m a bullring guy, besides, I can bore and sleeve in my garage, I’d have to send it out for nikasil
