    Looking for input on header choices for my 360. Need to keep the air injection setup, so looking at Fabspeeds with the thermal blankets -vs- Lettieri with the heat shields. I haven’t seen much feedback about the Lettieri, but I assume they’re much the same as Tubi being that Lettieri was the founder of Tubi? Pros and cons of either setup? Thanks!

    Agree, I received a set of Fabspeed for my 360 and sent them back, the finishing was awful and ended up putting tubi on my car.

    If you can delete the air rails try supersprint.

    I ordered the Lettieri manifolds. I was less than thrilled with some of the feedback I found for the Fabspeeds, and was honestly not a fan of their used car salesman tactics when I inquired about the “forum discount.”

    You did the right thing looking for feedback on fabspeed, as I have been advising others to do for years after a bad experience. You might have been fortunate getting a bad taste pre-purchase.

    Did you ask Lettieri what are the differences between their design and Tubis? Any claimed hp ?

    I talked to Lettieri this week, and asked them the same question. They said they put extra folded pieces of heat shield over the edges of the main shield for a neater appearance. Under the heat shield is a 6 mm thick felt mat. They also said they make their flange from stainless steel billet stock, while the Tubi's are microcasted. I asked if they machine the flanges flat after welding - they don't, but they do have an old 360 head they fit them to and sand the flanges if needed. They are 4-2-1 design - I'm not sure what the Tubi's are, and I've read different stories the original headers so I'm not sure?
