The only Big Block version I recollect of this is a Model Car Garage engine dress up kit that included resin valve covers (and different air cleaner types) with a PE version of the top. https://www.modelcargarage.com/eshop/pc/viewPrd.asp?idproduct=363

Got a set from Megahobby. These are great, along with the DSPIAE pens. Handy addition to the "paint shop" and great for some detailing. The valve covers on this 409 engine were done with DSPIAE Metallic Siver. I have yet to try any clear coat over any of the colors

https://www.firescalemodeler.com/ You buy from them. They are in Lisbon Portugal and ship to the USA. I have several of their paints. Comparable to Splash, Scale Finishes, Zero and Gravity (the real one in Spain).

I have this, but have yet to use

Here's a set of instructions from the Foose Version but has the stock components. Stock tires and wheels would look thus https://public.fotki.com/drasticplasticsmcc/mkiba-build-under-c/monogram-instructions/automotive-cars--pi/chevrolet/1961-1970/monogram-65-chevy-i/ I should have a set of these sitting in a box but need to check.

Arrived today

With a lot of cleanup and work I built this one last year.

Ahh, my bad. Missed that. Looks like they went back to the original box art from 1969. I didn't recollect another reissue, but I have one in the stash, so not much interest

Looks like the original. Reissued once around 2000. Neat kit and concept.

I figured it might be the case. But I didn't want to pull out the kits and check it out in detail.

I'd suggest starting here. I have gotten some figures from them. Big thing is attire. You may have to compromise/adapt for that as well https://www.etsy.com/shop/LuxFigures?ref=shop-header-name&listing_id=1534602045&from_page=listing

AMT did this in a kit I guess you could adapt the extended cab to this with some chassis mods. I don't recollect them doing a Promo of one either

You've hit the two main weak points of the kit. One other was the twin supercharged engine a little off on detail (if you wanted to use it)

The shortcomings of the Italeri California is the incorrect (GTO) engine (that can be reasonably fixed) and the GTO interior. Other than that, the Italeri Ferraris are pretty decent with some aftermarket parts applied. My 250 California already built Italeri Ferraris needing to be built (Yes another California and the Revell 275 is a reboxed Italeri)
