There is programmable “auto blip” — in the Holley system — or you can add (as we did) the auto blip box (easier). In fact — after the test drive - we discussed the auto blip needs to be “more” — and that’s all just programming.

Mostly what you’re trying to accomplish is to “unload” the gearbox..... Same thing I do with my Jerico in the ‘65 - it’s just a momentary “lift” of the throttle... to unload it and she slides right in. It’s a super fast movement and doesn’t involve the clutch at all on upshifts.... but with a Jerico, I do heel and toe and use the clutch on downshifts. Some guys don’t but I found it upset the car (probably crappy driving on my part) so I use the clutch.
