yeah, so maybe it can get away with a smaller cooling system/radiator?
Well that is the hope. Buzz on it for 60s at a time and see what happens.

yeah, it would even have a hard time overheating that quick.

I've successfuly overheated a stock car under similar conditions.
Solution was an electric fan, switched manually to be on all the time. If the coolant gets hot, you can still cool the radiator down with the engine off. Don't forget, the coolant isn't the entire cooling system, a copper radiator offers a goodly amount of mass available to absorb heat as well for short-term high stress cooling situations.

FWIW I talked to Jim Mederer today. He told me to look for an intake tract length of 16" from the side of the iron where the intake bolts up to the top of the trumpet.
like the rb holley manifold?

If that's what it was designed for then probably. I really don't know. We just don't have the cash to throw down on a new or used manifold though. Jim said using the TII lower would be a good starting point as the runner diameter will work well with what we're wanting to do. I forget the exact measurements since I measured it but it seemed like the lower was around 10". Actually, the upper and lower together may be real close to 16". He also since we're using fuel injection it wouldn't make much a difference to do ITBs or a plenum with a single throttle body.

well maybe t2 intakes are good enough? that would be cool!

I'll try to measure one of them tomorrow. My first, rudimentary measurement showed the front secondary runner being longer that the rear. So it will probably be a compromise. More investigating needs to be done though.

Finally made some time to work on this engine a bit. I pretty much finished the port in the front iron. It's drafted off an RB template. I promised the engine would be done by the end of the month. I won't make it but it should be close.
