I'd like to see it stock, with totally accurate spoked wheels and correct tires. A detailed 4 banger, with speed options, a dropped beam axle like Bill said, and some maybe some actual real traditional options would be great.
Similar to Arctic Sand which appeared on the cover of Rod & Custom July '57. Also check out Rik Hoving's fotki page, he's got a lot of pics of 41-48 customs. https://public.fotki.com/Rikster/11_car_photos/customcars_i_like/ford_custom_cars/46-48_ford_custom_cars/
As for me, I think it's a case of getting used to things being a certain way when I was a youngster. Now that better things are available, they just don't look right. The best example is AMT's "sectioned" 32 Ford. The accurate Revell kit just looks wonky to me. The Sizzler vs. Slingster suffers from this. I've read that the frame rails are the right size in 1/25, as is the tiny body, but it just looks wrong. Even accounting for the scale difference, when I opened the box one of the first thoughts that came to mind was maybe if I sprayed about 40 coats of primer on the frame to fatten it up it would ok. The Double Dragster did nothing to help that opinion. Being one of the first kits I ever bought, I got used to the thick old frame. So much that the Revell parts pack dragster frames ( along with the Slingster ) look terrible to me. I haven't measured either. I was going to say we should use the Slingster as a reference point until I remembered the slicks and non-dished mags they gave us. Might work on a 60's Jr. Stocker, not on a rail.
That would make a nice basis for a more traditional rod. The goofy parts can be replaced easily. The only issue I have is the reworking of the rear wheel wells. That would take a bit of surgery to fix. Greg, I don't think it's been shortened, I think that rear wheel well issue is what makes it appear like that.
I use matte aluminum exclusively. It does get shinier when burnishing, but IMO not worth worrying about. I think it looks better than the chrome sheets. Not the best view in this pic, but the chrome on the side spear is matte aluminum bmf.
