Sounds like you're good to go then. I'm putting together a gen1 Lightning now with a VR4. It's stock other than 36# injectors and a holley hp. Man I love the Holley. I've went to the Holley school last year well worth the money in my opinion.
Holley is awesome I changed the shops tune I was afraid lol he had the wot timing set a little high for my blood and he had air fuel 13.0 at wot but now im wondering if I should put it back and have her a take a pass see how it performs if I can get this to run 11.9x I'd be pretty happy considering it's full weight and still retains AC lol
VR4 has a lot of potential for vintage Paxton superchargers as well. Hopefully Craig gets some impellers and kits developed. I've experimented with VR4 style impellers and the increase in boost and cfm's is significant over the traditional SN/SN high efficiency impeller. I'm using the improved SN impellers in the vintage VR57 supercharger rebuilds which are converted to SN type internals. I looking forward to am introduction of VR4 impellers for my '57 Ford with VR57/SN blower.
I currently have a vr4 on a 93 5.0 mustang and it is beyond fast low 11s but it makes tons of heat!! You need a bigger cooler than what he gives you! He gave me wrong races in a rebuild also. I was very annoyed!! The vr4 was the ball drive of the novi 2000!! The vr4 is a good blower!!!
I would at least go with 42# with the vr4
