I was just told the pcm risers for my 454 are NLA. Which i didnt realize before. Now it isnt something i NEED to do but wanted to discuss options here for the "if and when" i need to adress them. Aside from getting a good used set from someone here what are new off the shelf options? ------------- 1988 Barefoot nautique-454 |

So i was shopping at skidim. https://www.skidim.com/mobile/products.asp?dept=1159 Looks like the factory sweep style is not available for the 3.5" thats on the bbc. They only list it in 3". They told me the oscar style that they carry in 3.5" will not mate to the factory pcm manifolds. So in order to run them you would need to change both manifold and riser to make them work. ------------- 1988 Barefoot nautique-454 |
