anyone know (F.I.R.S.T) www.firstinjections.com

I have long been looking for an upgrade for my 88 gta...I love the look and low end performance of LTR, but want more power up high....could this be the ultimate LTR style setup ?

http://www.firstinjections.com

they claim it runns strong to 6500 rpm on a 350

runner lenght 10,5 inch

base manifold port size (1 1/16 BY 1 3/4")

72 mm monoblade throttlebody

runner diameter 1 3/4"

base, runners, plenum, throttle body, fuel rails, all gaskets and stainless mounting hardware is 995 dollars

please give me all possible info and opinions

would be really interested in comparisons to the super-ram

Been around since the 80s but it never took off and the company folded. Apparently those guys bought the name/molds and are moving with it again.

Do a search, lots of people ask about it. Probably about as good as any LTR set-up, but not that many people running them and giving back results. It's only advantage seems to be perhaps a slightly better transition runner to base. Still looks ugly for the whole second half of the base into the head.
