Offy intake...
I am just curious if anyone here has input or experience with these intakes...
http://www.offyparts.com/product_inf...5e1eb152fd0473
I have been thinking about buying one for 2 years now...and still cant kick the thought.
Last year i got my daily friver 79 f-250 4x4 with a 400 to run 14.332 in the 1/4 mile here in colorado, and would like to do some more tuning ( if possible) and an intake swap to try to help me tword my goal of hitting a 13.999 pass one day this year.

i'm running one on my Cleveland at the moment, and i've suggested them to several guys seeking the ultimate torque combo but i really don't think anyone has taken me up on it. it's not a performance oriented manifold but if low end is what your after, it's a step in that direction.

i could deffinently use more low end, and usually do not go above 4600RPM on the top. Getting 5440 pounds up and moving is difficult.
How has it compared to other competetor manifolds? Pros and cons?
Thanks for your response.

I'm curious of this intake as well, what gains would I expect in an otherwise stock motor(351m) with fenderwell headers? ('78 Bronco)

I have had one sitting on a shelf for a couple of years. I cleaned it up and put it on my 400 a few months ago. I rebuilt the carb at the same time so it is hard to say how much improvement was due to carb. It ran fine before I did the swap. The only reason for going through the carb was because I had it off and said what the hell. Vacum is much better. Off-idle response is much better. I had a Weiland action + installed prior to the Offy. For a daily driver I really like it. I never get over 4000 rpm so take it for what is is worth. It seems to idle better and run out smoother, but this may just be perception. It in a 1978 Bronco.
