Did you ever test fit the Victor and TB? Kind of a moot point, but I'd still like to know if it clears. If it hits, I would feel even better about going with the XT, lol. I'd love to see your setup 451. I bought the same thermostat housing and agree that the big holdup is plumbing the air intake with the XT. I really think there is market space for someone to test fit a few units and sell kits. Most of the "you build it" kits are plastic and I'd venture to guess that most DIY guys have MIG welders, not TIG, which results in needing to outsource something. I have a Holley Terminator Stealth Kit that could have gone on either car...ultimately selected to guinea pig the Duster. My initial plan, assuming I was happy with the performance, was to replicate the kit on the Charger...that way I could stock replacement/roadside parts. The Pro-Flo 4's price is tough to beat...you get MPFI vs TBI and the distributor included. I gave Holley time and expected they'd have had an answer by now...not the case. If you are going with fuel injection, MPFI > TBI all day, every day. The only downside, if aesthetics matter, is that it is harder to conceal. Couple the fact I might eventually run a ProCharger and the XT option made even more sense. There is also the ability to screen record via the tablet...I'm thinking that is a feature not many are aware of. Here is some info: https://forums.edelbrock.com/forum/...se-tablet-screen-capture-app-as-a-data-logger The other big thing going for Edelbrock is tech support. I always heard how great Holley was. Maybe I have bad timing, but I couldn't get anywhere with them. I can't call after hours, so I'm left with (2) 15 minute breaks and lunch. Couldn't get thru on breaks, finally spent a full hour waiting only to get someone that said they were a carb person and couldn't answer...nice guy, even said he'd have someone able to answer call back...never happened. On Edelbrock's side you have a forum. I can post something at 11 PM and have an answer the next day at noon. I'm sure some like the phone call option, but for me and my schedule the forum can't be beat. I think both sides have their pros and cons. What I am most proud of is that we are finally getting affordable EFI options that are constantly improving thru innovation and technological advancement. The competition doesn't hurt either...keeps the prices in check. I never ran FiTech, but I give them credit for making the price reasonable. I look forward to my thumb getting better and getting to play with both systems. I feel Edelbrock could easily crank something out like Holley's Digital Dash in the future. But for now, a $100 included tablet will suffice for most. I also think the XT is a great manifold for MPFI!
