Anyone out there have 1/20 Chevy small block V8 engines or 1/20 kit parts? A drawing? 1/25 or other size model parts?

So I discovered there was a Bandai McLaren Mk6B kit, and the McLaren Mk6 is one of my very favorite racing cars- yeah, looks a little narrow and slab sided, but there’s *something* about its shape, still a whiff of romance, that the Mk8 seems too efficient to capture. And now I’ve got one of the Bandai kits, or most of one… its a real relic of the 1960s- the body looks more or less right, the chassis guts are simplified to toy proportions, the steering has big, beefy, parts that allow you to set it to go straight or curveed, and the model’s engine conceals a Mabuchi electric motor that drives a gearbox (in the gearbox!), which drives the rear axles and thus the rear wheels.

I can certainly manufacture my own replacement pieces for what’s missing- some of the rear suspension bulkhead, some suspension arms, the one-ball Hooke joints for the rear axles. But so little of it is ‘scale-like’ that I’m more tempted to try to turn what I’ve got into a scale model. One of the MPC McLaren Mk8D kits could be a donor for much of this- the 6 had two more structural bulkheads- one aft of the engine block and connected to the chassis tub, for rear suspension loads, the other at the front edge of the front suspension. These complemented the two bulkheads that both designs have, the firewall/central bulkhead between the engine and the driver’s seat, and the forward bulkhead that caps the tub at the rear edge of the front suspension.

But the suspension geometry, arms, hubs/uprights, gearbox, axles, brakes and wheels all translate directly, and a hybrid tub using parts from both *and* scratch built parts for a Mk6 would go a good distance to supporting the body of the Bandai car.

However, the Mk6, in McLaren Car’s team use, carried a Chevy small block V8, not the big block moster (540 cu. in.) that the Mk8 used both for power and as a loaded memeber to carry rear suspension loads to the tub. So I need a 1/20 scale Chevy small block V8. None of the 1/20 scale Corvette or Camaro models seem to have a small block engine (duh). I found a couple of Chevy kits with 1/25 or 1/24 motors that I think are small blocks:

Revell 1969 Z-28 RS kit, with 302 cu. in. V8 <- this has gotta be one…

<AMT?> 1969 Camaro SS, with 396 cu. in. V8. Big block destroked? small block bored and stroked up?

<someone> 1966 Chevy Nova – seems like it should be a 350 and not a 427/454.

I’ve got profile/outline views of the Mk6a, and a number of picture books, including the recent, “Bruce McLaren, Racing Car Constructor”, (Thanks, honey!) that I can mine for useful photos to draw up a plan. There’s no way I’ll get this done this year, so looking for the parts I need seems to make sense. Soooo, if you have 1/20 parts for a Chevy small block V8, please drop me a line. If you’ve got a good set of drawings or photos of a Chevy short block V8, and can share them, also please get in touch.

Thank you!
