GT40 Heads...again

Quinner said you are good at sucking things dry.

Finally got around to CCing the GT40P heads. They are 60cc's. I have a side vent window that I have not installed yet and it is drilled for the plastic latch so it worked perfectly, just laid it over the chamber and filled through the hole till full.

Started tearing down the motor and found I need to replace both exhaust mainfolds, they're both rusted through and starting to crack.

Pulled the water pump as I have to replace that also and found a good deal of rust and scale. This boat came from texas and was probably never winterized. With only 280 hours on it when I bought it I suspect it sat for long periods of time without running and rusted up. One more good arguement for filling the block with antifreeze in the winter as opposed to draining I guess.

Good news is I got all my chrome back yesterday, looks awesome. I bought all new chrome pieces for the steering bezel that are still available and had the speedo bezels and a few other pieces rechromed. Looking pretty good now.

Does that mean you'll be upgrading to some Hiteks?

I've got a few options and must admit I looked at the old thread on the HiTeks but that's just a little too much money right now. I could buy a lot of new ski toys with that kind of cash.

Chris, I was wondering what you were going to do with those manifolds once you upgraded, I am interested. I guess I can wait til spring but I'd like to have the boat running by April. I shot Rob an email too since he's dropping in a new powerplant his may be available sooner.

Shoot me an email with a price please, maybe we can work it out. Thanks

81- my lord does that suck. On the positive side, that boat should really roll when it's all done.

81, I have a set of slightly used Keith Black Silvolite hypereutectic pistons P/N KB-181 and Seal Power rings for sale. They are .030 and I beleive would be great for your project. I also have 2 camshafts listed under the for sale link if your motor is std. rotation (turns a LH prop). All parts fit the 351W.

Both Clevite and Federal Mogul offer cams for reverse rotation engines. You can get a cam with the same specs as the Clevite cam I have for sale on this site (except reverse rotation). If you want a special order cam (of any rotation or specs) Comp Cams can grind it for you. They are located in Memphis, Tenn. They also have a very extensive website. Check them out!

You have a good point there Gary, the early 302's and all 289's used a different firing order then the more recent 302's and 351's. The camshafts are interchangeable on all SBFs (taking rotation into account), however using a camshaft with the revised firing order (302 H.O. and all 351Ws) will force you to change the firing order.

These are the guys that will be doing the machine work on my block opel engineering anybody up here ever use them?

They talk a pretty good game and the shop is pretty impressive. Had an answer for everyone of my marine engine questions, Will probably drop the block off early next week.
