No I ended up buying a Porsche 930 & swapped a SBC in it. I only come on here to lurk on this thread. I have thought about buying another 510 though. I miss it everyday.
dude just fix the hood hinges, install all the interior parts, get in the car and enjoy it. Dont tackle a big project while we are having this perfect weather. When the sun is out, leave it parked in the garage but at night the temperature is perfect. Get in and take the misses to get ice cream as soon as the sun sets.
I can see why they would create this new rule. A lot of good looking and rare cars are left out of these shows because all the spots are taken up. Like they always say at these shows, "the real car show is in the parking lot". Im pretty sure the "unfinished" cars will be there and their drivers will still go.
You'll never know until you try. Be a pioneer. All the info on the internet about swapping a s13 sr20 into a 510 says that you have to use a top mount manifold or use a more forward mounted bottom mount because it will hit the steering box. I had nothing to lose and gave it a try and my car has been running for 5 months with the OEM bottom mount manifold.
