Alan Gow suggests it makes no difference to fans if all the race cars use the same engine -- subsequently, the vast majority of entrants in the BTCC use the category "Swindon" engine which is based on a GM engine. The trouble locally though seems to be complaints from Ford fans about Fords using Chevrolet engines, or from Holdens fans about Holdens using Ford engines -- Casper has solved the issue: use an engine from another manufacturer entirely.
The Dodge 6.2 Hellcat crate engine should do the trick:
707 hp @ 6,000 rpm
880 Nm @ 4,800 rpm
$15,900 USD / $24,700 AUD

Seems a fairly affordable way to get 707 reliable Dodge horsepower.
The only concern with the Dodge Hellcat is that being supercharged, does it suffer heat soak when it is run continually flat-out for long periods of time? It has an air-to-water intercooler sandwiched under the blower, but this might need to be tested and perhaps upgraded.
Thoughts on a category engine for Supercars and what it should be?
Otherwise it could be the Chevrolet LS or LT (direct-injected LS).
Or it could be the Ford Coyote. Probably the standard 5.0L block, as the bored-out 5.2L uses "plasma arc spray-on cylinder liners" and can't be easily honed or rebuilt. Pairing a flatplane crank with an unequal length header,
like the Shelby GT350 Mustang, would give the Supercars category a fun and unique sound.
What other options are there?
