What would you build if limited to 372ci - with boost as an option

The other issue with the R motors is the prelube and oil heaters before each run. Not that it would be a deal breaker, but watching those running the Nascar motors do that each run seems like a pain without a crew helping.

An oil accumulator makes that pretty easy. We run one on our truck and before every fire up we pump oil through the engine with it. And you don’t need an oil heater, just run the engine for a bit. We run our junk on jackstands to heat the engine oil, trans fluid, and diff before a race and it only takes 10 minutes or so to get some heat on the oils.
