Hey all,
Not naming any names here, but a certain crate engine builder has my block and heads assembled and is recommending the F.A.S.T. system over Mass-Flo, mainly I think for cost reasons, ease of installation, and tunability, but I picked this builder mainly because they are an "approved" Mass-Flo crate builder. Curious that they're recommending something else though . . .
Anyway, to sum it up, after much research, (though rusty, I did most of the research a year ago) I'm pretty sold on the Mass-Flo kit for the following reasons:
- It's a known system with Ford parts (except for the GM that has a lot of support and a large knowledge base out there for that reason. Anyone that could diagnose a Ford EFI system should be able to diagnose the Mass-Flo.
-Self-adjusting to real-world driving conditions. It seems like it would have tamer street manners than any of the various TBI systems out there - FAST, BOSS, Retrotek, ad infinitum. I also will have a relatively low compression, 9-9.5, so I can add forced induction later if need be.
-Not a TBI, which to me seems to beg the question, "why not just use a carb?" - carbs are great, and for peak power and tunability seem to be unmatched, but I'm after real world driving conditions, manageable power, and MPG. TBI offers some of these, but not seemingly as well as Mass-Flo.
-Good support from the company. Mass-Flo seems like a quality outfit. Seems to have experience with 351w strokers with their kit.
-Ability to go with forced induction if I ever go nuts and add that, and support for that.
What do you guys think? What's their motivation for recommending this FAST kit? Just kick-butt dyno numbers for the initial run? I know Mass-Flo takes a while to "learn" and might not produce a peak dyno run off the bat.
Thanks for any wisdom in advance . . .
