Bore:  4.370 in.

Compressed Thickness:  .039 in.

Compressed Volume:  9.700cc

That's thicker than .035.  You can refine the bore size to match your block with a Cometic.

For example, if your bore is 4.280 the difference in CCs would be 0.391cc.  Not a whole lot, but every little bit adds up.

More importantly, sealing surface area is sacrificed by going with a larger bore diameter gasket.  I feel that this is an area that can promote burned heads and blocks.

Only thing I'd add to this is to keep the size of the cylinder chamfer in mind when sizing a head gasket.  Every bore has to have a chamfer to allow the rings to slip into the cylinder.  I've seen them range from .010 to .050 per side (so double that for over-all OD) depending on who chamfered it and how.  If the ID of the gasket rests on the chamfer there is that much less surface of the gasket sealing and combustion can actually work it's way under the fire ring.

NICE!  Looks a LOT like my Tahiti.  Kinda digging the rear cover with the spoiler.  Got any pics from the side / rear?

Can I get some info on the distributor and wires?  Brand, gear type (looks iron?), trigger type?

Are you willing to ship to Hawaii? 

Thanks!
Chad

Thanks Chad. If it was your kid, believe me you would do the same. I'm nothing special, but Bella is. Thanks for the kind words.
I also see your from The "Big Island"... I haven't been there in 30 years, but my dad (I guess that means I am too) is Hawaiian/Portugese, and is from Maui.

I'm actually on Oahu, The Crowded Island!  LOL!  Carvalho is a fairly common name here.  Was gonna ask if you were Portuguese (or "Portagee" as we joke around here).  If you're ever back in town hit me up!

No progress on the boat it's self, but made a dent clearing the spot I'll be keeping it.  Couple more days of clearing and I should finally be able to bring it home.

Ken,

Thank you for sharing these touching feelings and moments of your life with us.  Having 2 boys of similar age it really struck home how quickly life can change.  You have my utmost respect for overcoming unimaginable challenges and everything you've done for your little girl.  A lesser man would have folded.  Hell, I may have folded!  But you stuck through it and got to see your little girl happy again.  HUGE props to you.

I can see where your girl gets her fighting spirit from.  Seems as though hard work and tenacity runs in her blood.  It's so awesome to see her laughing and smiling again. 

Best wishes to you and yours,
Chad

Excuse my mad Paint skillz... but here's a rough diagram on how they're typically wired:

IIRC, that spark plug is already fairly hot.  I think 46 is the max.  If you're fouling 45s I don't think it's a heat range issue but perhaps a mixture or ignition strength issue.

You said 1 of the wires goes to the ignition switch, right?  That's the switched 12v. 

Resistors are typically only used on a points style ignition system, not the charging system.

The field wire should have a switched 12v signal.  So long as the volt meter is reading around 14 you're golden.

More than 1 for sure.  We can do a day at the Sand Bar if the boat is running by then.  Any excuse to get out on the water!  :thumbup:

Wow, I see so many parts I need!  Wish I could just buy the whole boat,  LOL! 

Are you parting the whole thing out?  It has a bunch of stuff I could use.  Hate to kill it like that, though... seems like a nice float in the pics.

SPF to Chad!

Thanks for working with me on the shipping arrangements, Steve!  Looking forward to rocking these on the bay.  May even save me from having to make side panels because I'd hate to cover them up!  LOL!

As stated above, voltage should be right about 14 with the engine running.

Depending on your pulley setup it may take a few RPM to get the voltage up.  Try revving the engine to 2k and see if there's still no change. 

If it's still 12ish at 2k then get the alternator tested.  While testing make note if the guy hooks up the Field wire to excite the alternator.  Once you've ruled out the new alternator being DOA you can proceed with wiring.

Thanks for the info, guys!  I'll be sure to check the bilge and sub floor areas well.  Floor seemed solid but I'll triple check it.  :thumbup:

Do you have full stringers?

I've been checking out various interior options for these boats and one thing struck me... It seems like all the pics Ive seen the floor is flat.  On my boat the floor is V-shaped (see pic above).  I feel kind of dumb asking this but...

Am I supposed to have a 2nd floor in there that may have been previously removed? 

I'm thinking yes but I can see where seats were mounted to the existing floor.  I suppose someone could have ripped the sub floor out and glassed seats into the hull.  This boat is 37 years old, anything is possible. 

Can anyone shed some light into how this is "supposed" to be set up?  Any info appreciated!

96
Love the look of the hull.... but I'm kinda partial since it looks exactly like my Tahiti!  LOL!

What do you mean it's really thin for the kids?  You mean how low it sits to the water?

Looks like you've got some cool hardware on that BBC.  The exhaust guides actually pass through the water jacket in the head.  If it moved for whatever reason (valve seized, bad fuel, bad installation, etc) it could cause the leak.  A pressure test at a competent machine shop will tell you for sure.




(I know I'm a N00b here but I manage a 10,000 sq ft automotive machine shop.  Not saying I'm a guru but I have a bit of engine experience I'm happy to share ^-^ ).


BTW, warp spec on those heads it .004" overall.  On higher performance engine if I can get any feeler gauge under a straight edge anywhere on the head I recommend a shave.

Good luck with the project!  Looks like a blast!

The engine was thermo-cleaned and shot peened before getting bored .060-over.  It'll be a 469 when it's all said and done.  The TRW forged slugs were a little on the large side so by the time we added some clearance it got an extra cube... lol!
