[Tigers] Air cleaner & horsepower

[Rense, Mark (GE, Appl & Light)]

All,
I built a fairly mild 5-bolt 289 (Performer 1.90" heads, 500 cfm 4bbl, F4B,
CompCams XE262, Eagle rotating assembly, 9.5:1 compression, Pertonix in
dual-point, stock exhaust manifolds) for B382000991 about ten years ago and
when I ran the car on a chassis dyno I tried several air cleaner combinations.
The best run was with a standard Edelbrock air cleaner with 4" element and the
car peaked at 273 HP at 6200 RPM. I put the stock Tiger air cleaner on with a
K&N 1 1/2" element. The flow was so restricted I had to open up the carb and
drop in a leaner set of secondary jets. The best we could get out of that
setup was 254 HP at 5800. So, the 20 HP loss is reality.

I just finished another 5-bolt 289 with a 332 kit and it is scheduled to go on
the dyno tomorrow for break-in and set-up. I plan to run a couple different
carb/air cleaner combinations, so I will include a stock Tiger air cleaner if
I have time. I have both 1 1/2" and 2" K&N elements.
