Here is another example of our VR-200 heads in a real world application, not just theoretical BS. This is a real streetcar, it is all steel except the fiberglass bumpers. It has a 422” engine that runs on 92/93 octane pump gas. It has a TH-400 trans (not an optimal NA trans) a 4.10 rear gear and a 28” tire. No hood scoop and uses a victor 340 intake with a .640”/.620” lift camshaft. It weighed 3165 lbs. on this pass. There is nothing trick about this package, just a standard type build with good parts selected. This car drove roughly 900 miles and made passes at 4 different tracks over a 5 day period. His 5 day average et was 9.954. Not too shabby for a factory replacement aluminum head.
I’m not sure how to stop the end of the video and post it on here but, if someone can let me know, I would appreciate it. I’m always willing to learn.
