The deteriorating gas tanks have been removed  and the straps that secure them were mostly completely rusted thru.  The muflers are going to be replaced as they have rusted thru also.

There was a dangerous situation in the exhaust system where the 4.5" dia exhaust coming from the copper engine collectors needed to be reduced to the 4"dia. Coper pipe going back to the mufflers 

 There was auctually steel welded to the end of the copper pipe for the reduction which seems crazy to me that chris craft could have chose  to use dissimilar metals. When I dismantled this area it became apparent  that a rusty slury had been leaking in this area for many years but went unnoticed being hidden outboard of the gas tanks which are now removed. After speaking with Tim Toth today it sounds like he also has this same exact reduction in his otherwise copper exhaust system.

The 427 are also getting some much needed  work. The intakes will be replaced as there are holes in them. All the  hoses and seals , half of the engine mount bolts were either rusted completely thru or broken so they will get replaced along with a few engine mounts which became fused to the broken mount bolts with years of water dripping on them.  Because of the broken mount bolts and rusted out lags the hold the additional Douglass fir engine beds I will also be replacing the wobbly  engine beds as needed to assure that there is a solid engine mountig surface. While the engines are apart  everything will be inspected and adressed as needed as well.

Brand new tanks and fuel lines will be going in 

All new wire harness to the engines and all 12 volt wireing in the dash.

The helm is also gettig an overhaul repairing the stress cracks, restoring the gauges, replacing the switches and getting rid of all the extra holes that have been added over the years. 

Needless to say ill have to sleep sometime next summer as i work on customers boats all day at work and then for "fun" im working on my commander most  nights and weekends

As this is a rather monumental side project

Heres a few more photos of the project

Ive been removing loads of grease and grime and the engine room is pretty much as empty as it could posibliy be rignt now. 

Wow Jeremy, that looks like 3 winters with of work!? I’m sure she’ll be beautiful when you’re all done.

Is prepping that area for paint not one of the worst jobs? I thought I had my hands full with just doing one side. A power washer definitely helped make short(er) order of the task. I’m generally pleased at the cleanliness at this point. Now I’m just waiting for good enough temps to let me get down there are start painting. Was really hoping for next week, but it’s due to be in the 30’s. Maybe I’ll catch a break one day.

Is the thru-hull in that one pic for the motor?

Matt  the thru hulls are my engine intakes and im auctually going to be glassing those in and moving the intakes to under the stairs like the later 35s .  My boat is hull 10 and I  think they realized that it was not a great location for it and made a running change  after my boat was built

Yes, the cleaning pretty much is awfull. What does everyone use to scrub the grease  from the dreded hollow  keel?

Im using undiluted degreaser  and it is doing  a decent job but man I've tired toilet  brushes, scotch bright pads, wire brushes, tooth brushes with no real winner. 

Not sure what you mean by the “hollow keel.” But I got pretty good results using Gunk engine degreaser (the heavy duty gel), giving it a good soak, scrubbing, power washer, then lots of rinsing. The amount of water I went through was obscene.

When I did mine during repower it was Spring and I first power washed after about a pint of  Dawn and scrubbing, repeatedly.  After it looked similar to mat I donned a vapor mask, chemical gloves and started in with solvents until everything sparkled.  Returning in the morning I would find oil leaching out of some invisible portion and repeat the process.  After about a week there was no more leaks and I applied the bilgecoat sealer.  I didn't coat the keel well since the genset takes up so much room.  There were many recovered "treasures" from under the genny since there was sufficient time to do the discovery.

I did consider filling the vee but figured it would not seal properly and result in trapped moisture, oil, dirt, etc. not to mention dislodge at some embarrassing point in the future.

I did the same thing minus removing the engines on my 31 a few years ago. New tanks, exhaust, clean and paint the bilge. I had bigger aluminum tanks built and had my mufflers reproduced in 3/16’s stainless. 

Good ideas ill try them all. I was also thinking of trying oven cleaner. 

Looks like you did a nice job

I lime your tank mount brackets and the custom mufflers 

How do your new mufflers sound in Compairison with the old cast iron ones?

They sound exactly the same, which is what I was going for.

The bilge is now pretty clean after weeks of very repetitive  scrubbing . An absolutely awfull step.

Anyway my 427s have been removed and completely opened up  and a bunch of their past was uncovered.  Apearently the port block was replaced at some point in the past as it is a 72 block while the stbd. Is the original 68. That port block was also  sleeved  and both blocks were bored 20 over . The machine shop also discovered I have 428 cranks and said with these previous modifications on my engines makes them right around 460cid .  An unfortunate discovery is that I discovered my boat spent  some time in Baltimore for I'm  guessing around 4-5 years with no closed cooling system. For some reason the stbd. Engine faired much better than the newer port block which suffered a fair amount of deterioration to the iron . It also has a hand full of cracks between the cylinders and water passeges. 

This led me to start hunting for replacement blocks along with a whole host of other parts I need  . 

Intrestingly I did find a company in calafornia called BBM that now casts brand new FE blocks in iron or aluminum that are CNC machined (wow the photos look impressive)

However that said , while I really intended to save these old FE engines , I cant ignore that I'd be aproaching the cost of new engines to keep "original power"

So ive been putting in time into reserching repower options.

Im between the proven 8.1s  and having a pair of small block strokers built. 

Price wise they would come out very close to each other. 

On paper the custom strokers look like they would put out the torque and power of a big block while weighing a lot less , burning less fuel and taking up less room in the bilge (which is especally atractive to have more working room between the front of the engine and the bulkhead)

However maybe its just old school thinking but I cant help but think about the old saying about no replacement for displacement.

I know many of you have chosen the 8.1s and have been very pleased but I would really like to hear from any of you who have gone with SBC Repowers. 

Wow Jeremy, I can only imagine you and I have been chasing each around the country these past few weeks. When MY port engine was broken apart, we discovered a piston had broken, the whole engine has been over-bored during a previous rebuild, and the only options were to consider sleeving, a new block, or a different route. Amazing how similar our stories have been these past couple weeks.

I wonder how many people across the country we’ve called back to back that are probably now wondering why CC 427’s are dropping like flies. Ha!

Good luck with your continued search. I considered doing the 8.1’s for about 1 email and 2 phone calls. While I’ve always tried to give my old girl everything she needs, that price tag was a bit much!
