I ordered a Cam and will be needing an AFPR with not much money left :-S
Which one is the cheapest one worth buying?

The engine is 87 305 TPI.

 

Mallory AFPR for $60

Holley $95

The Holley is more money, but I like the way it adjusts better- more of a thumb wheel dial on top. Getting a wrench into the adjusting nut on most APFR's is pretty tough once the Plenum is installed.

You can also modify a stock unit. Do some Google searches for DIY APFR mods. It takes a nut welded to the top of your APPR housing, and a bolt that will move through that nut to adjust the pressure on the spring. Not to difficult, but finding the instructions and pictures will be nice.

 

Thanks a lot. I was looking at those two. I bought the first one cause I had exactly 70$ left on my account. :-))) Hope it works fine and won't give me a pain in the ............ :-)))

 

I like the holley one because of the way it adjusts easily by hand w/o tools. but mallory makes good products so im sure you'll be happy with it.
