I think we have track results that show what a TrickFlow heads are capable of.
@-Boosted- and
@73smallblock both have solid 10 second non lightweight dusters. And both of those combo’s have room to grow.
@-Boosted- ran 10’s first time out with a new car and new engine and at Vegas. I think that’s better than dyno results. I’m sure there are a few Edelbrock and Speedmaster ET slips floating area. Trouble is both of the examples I gave above although newer have some good pieces in them.
