MFI concerns...

Agree about the sound - it sounds like the ultimate sewing machine at speed.
EFI can match or exceed the throttle response.
Some people like to keep a car original for aesthetic reasons. Unfortunately, others "are not about to ruin [their] car's value" and are only in it for the money
Anyone who wants the wt. can pm me. I've posted that info before and as David Byrne put it: "Say it once, why say it again?" - Psycho Killer

I would trust Randy's data - he probably has this broken down to all of the components. I know his approach is very much oriented to less weight - improving power to weight ratio. Nothing wrong with that. Again, all depends on what experience you are looking for and your objective with your build.

Yes, I'm a hotrodder. I agree with your post above and also seek a sporty vintage experience. An evolved one - with suspension upgrades that Porsche might do these days. At some point you buy a Singer or pay a visit to Alois Ruf or Robert Linton (who recently posted to his thread BTW) tho. I wanted to build a car myself and make it as light as I could at reasonable cost. If I were the CEO of Oracle I'd build the unit body out of carbon fiber (instead of $$ on fast sailing yachts). In a decade or so, all IC motors will be vintage efforts.
I researched MFI extensively years ago, and finally went with PMO carbs. You could get Motec back when I looked at this for my own car but the cost, and difficulty of working on the system on a lonely mountain road miles from a cell signal made me go with carbs.
Today, I might just go with EFI and a Mg cased motor instead of the 3.2L I built. The EFI in an MFI disguise is a viable option if you want that look. IIRC, it is a Gamrothian product.
OTOH, you might want one of each... The look & feel, the experience is what I and many others are after. It is almost like a piece of HiFi stereo equipment - the looks and the ergonomics are important once you are in the same performance ballpark of various units.

^^agreed!! Isn't this much more fun to talk about our beloved Porsche's to distract us from this crazy situation our world is in right now!? There is no right or wrong answer to these things - many flavors to suit your desires.

Oh, and by the way - there is still quite an interest in MFI. I reached out to Mark Jung earlier this week to find out where the heck my pump was. He told me he has 15 pumps lined up for work and is booked out for months - not even feeling the impact of Covid-19 on his business. My pump is being worked on now and will hopefully be done in the coming weeks.

I'm looking at a '72 hotrod w MFI. The 2.7 liter is actually more like 2.9.
I've heard that the MFI can be tough... e.g hard to find people to work on them. Especially when the displacement isn't stock and the MFI hasn't been tuned for it.
Anyone have experience to share? What should.i be asking about? How

Speed Test Scrabble Word Finder Solitaire hard is it to get the MFI working correctly w the 2.9 liter when it was built for the 2.7?
Thanks!... CP
