IÂ’d like to say thanks to all my fellow boaters who helped me with technical advice or parts on my winter 454 upgrade. I just finished the last touches on the engine a few minutes ago and hope to get it wet tomorrow. The whole project started because I measured low compression on cylinder #4 when winterizing last fall. I pulled the head in January and discovered a huge crack. Ultimately the cracked was most likely caused by a clogged oil cooler (donÂ’t forget to change your impellers!) that lead to overheating. So my quest for cheap power began. All of my parts and 99% of my advice came from ***boat, Midwest Boat Party and Off-Shore Only members! HereÂ’s the specific thanks to those who helped:
- Chevy 781 heads w/ larger 1.88” exhaust valves – thanks Ray! (MWBP, Wichita)
- Valve springs to fit the heads existing machining – thanks Chris! (HP, aka cstraub, Tenn)
- Edelbrock Performer 2.0 intake – thanks Randy (HB, aka V1800J, Texas)
- Stock exhaust from 496HO – thanks Leon! (HB, aka FRENCHIE, Cali)
- Thanks also to Ray @ Raylar for providing dyno proven data on how good the stock 496 exhausts are and how much of an upgrade
*** But the biggest thanks goes to Loren (aka CarnivalRide) for loaning me tools and fielding my nearly daily questions. Loren knows BBCs inside and out and his advice on this project was beyond invaluable!
Thanks again guys!!!
