All over the place. I would have expected the typical...5.011 or 5.025. Speedcrappers are supposed to be .050 longerthan stock, so around 5-5.03.
Their vj is bare essentials, 2 angle.
72,58,45,33 work very well. I dropped using 15 for 18 if I do at all. Ootb for me They go turbulent after .520, peak at 245-247. In my bench. Not racing those though.lol
If they can only cast something that didn't fall apart after .500 that would be a true out of the box head. Tubing the pushrods is definitely for a track head it can be done on the street if it's a monster type build ragged Edge and tons of gear and all that. Those reading should realize that's what we're talking about, not budget or Iron heads. At 300 ea bare... you can experiment n try all kinds of **** and be at no real lo$$. As usual great thread, thanks for sharing
