R5P7bantam I'm with you R5's are built from the main web up for RPM.

Not fair to compare to LA engines.

But, in their defense. I ran W8R3 for over 15 years. Ran Arrington headed R block before that. They are not high maintenance. I put thousand of miles and passes on the Arrington. It was built for 1000 Mile events in craftsman truck and arca. The W8 nitrous combo had a couple bugs early. Nothing serious just learning. No one was doing 457+ cubes with this stuff then. Once we got oil returning to pan if was pure joy. The 421 was turned 9,200 regularly. Once a year valve springs and aluminum rods. We hotlapped every weekend.

Look at the dyno sheets. Brett now builds more torque in the 7K range so the RPM can be run lower. Plus PAC springs outlast the triples three to one. I built all three of my engines far cheaper. Gas was also $1 a gallon. Builders wanted $30-40K back then. Keep making excuses. Truth is it's a pretty darn good combo and 200# lighter than big blocks.

To change the vibe, don't even get me started on how affordable R5P7's are at 800hp.
