| Post subject: | Exhaust Manafold Replacement |
Ok so the lower water tube has just about pissed me off to the point of no end. I have about mad up my mind to replace the exhaust with a Barr Marine system so that i will have easy access to the spark plugs, better exhaust flow, Gain some power, and overall have a more efficient exhaust than the old omc design.. I am interested in finding more information and if anyone on here has swapped out the omc exhaust for newer system. Any information is appreciated. I am awaiting an email from Barr Marine with some answers to questions that i have about their system and options. THANKS ALL FORD 302 5.0L HO EFI (Fuel Injection) |

Talk to Deafwish about his Aussie SST risers. I had them quoted once and they were listed at $2500/set (pair), but manufacturer talked to me on the phone and offered $2000/set. |

Is yours a Ford 5.0? I'm going to have to replace my exhaust in about 2 seasons and am going to try to adapt the Merc dry joint design to my 4.3. It will take a pair of later model exhaust pipes used from the 94/98 V6 models because these use a 4" hose on the riser end and a 3.5" hose on the y pipe end. |

per Brad @ Barr Marine Manifold PN# FM-1-83 Riser 4" PN# 20-0100 Riser 3" PN# 20-0082 and I should see a 5-7% gain over stock so that would be a 15.75Hp gain or bump the block power to 236-240Hp based off of a fully stock motor. SIDE BAR i am planning to do a few other things: full MSD ignition to smooth things out and help eliminate the fouled plugs from excess idling, higher flow intake and aftermarket marine performance intake, all in combination with a new map curtesy of my mustang buddy. I think if he can make over 1,000hp out of his 351 he is legitimate to help me wake up this 302 a bit. SHOPPING for deals has begun. MORE hunting on MANIFOLDS continues |

I had a filter custom spec'd to K&N but have not heard back from them... I'll call again and see if I can get a price. Was the largest filter I measured to fit in the tiny opening we have. Other then the performance gain, what' the advantage of the Barr over stock? Which MSD box? I am ordering an MSD Blaster TFI coil to see if that will help why it is hard to start after sitting for more then 15 minutes when hot. |

The 5.0 and 5.8 Ford OMC/Volvo engines with the stock manifolds are a bear to change plugs. I found this flex socket to work a lot better. http://www.sears.com/craftsman-5-8-in-s ... ockType=G1 Trying to use a standard spark plug socket and universal joint just didn't get it. |
