I picked this up late summer and just started the tear down for rebuild by April 2020. Here's the progress and updates daily/weekly. It's had different motors and interior, when I got it there was an Olds 455 and junk interior. Old's had two dead holes and my BBC had just spun the bottom end, so pulled and sold the OLDs rebuilding the BBC. This boat has been on the site a few times and really needed some love so here we go!

HA HA sorry about the sideways pics!

Day1 compression test and pulling the Olds

Day 3 Foam and pump removal.

We did this for a couple of reasons;
1. typically with a boat this old the foam is full or water and or mold, so it's best to remove it
2. the bow eye is messed up and cannot be fixed properly with out some new backing and fiber glass on the inside.

I was thankful the foam was not water logged or moldy, got lucky.
Foam filled 4 55-gal bags due to shovel and hand size removal. Only 20lbs total, I really expected 40-80lbs

Also pulled the jet pump to get rebuilt.

Day 4 Floor removal - NASTY

Someone added a cover-up sheet at some point which trapped the OG floor and foam in, so water could not get out. So it just soaked, rotted and molded.... This is kinda what I expected of the bow foam.

75% out so Day 5 is gonna be nasty with a grinder to get this all out.

The vibrator tool worked ok. I was scared to dig deep and go thru the main hull glass, but when I realized the floor was actually two floors I was able to get after it for the most part. The OG floor is way better glassed at the edges so I'll have to grind it off and try not to burn thru the main hull.

The OG hull glass looks perfect under all that crap when wiped out it's still sealed and clean, different epoxies I guess.

Day 5 was as expected for the most part, nasty grinder action. Got it all out now need to DA it smooth and decide what to do about stringers. Gotta find some kiln dried wood and marine plywood.

Full on white out, had the fan blowing it out the shop door but that didn't help much.

Day 6 was easy... load up the knocking engine and drop off at machine shop.
Rebuilt should be a BBC 468 8.5:1 basic build up.

Way to get after it!

Are you putting a blower on it?  If NA, I would strongly recommend more compression.

Flusher the previous builder set it up that way using some of his old boosted parts, but I don't have a blower or turbo "yet"... I will if I can $$$$
Jordan it's a day count based on actual days working on the boat not actual days/time in a row, ha ha

Back at it after all the XMas and New Years trips (Glamis & Parker)
Day 7 - pull the trailer out from under the boat to get rebuilt, make dolly for the boat and prep for new stringers.

Going to sand blast the trailer and fix all the years of abuse, rust and old bits...
Only found one major item we didn't see when purchasing, there's a screw poking thru the bottom of the hull from whoever botched the previous floor repair.  Other wise the bottom is as expected with rock/sand rash from beaching. All that will get sanded down, glass added and re-gelled.

Day 8 - stripped down the trailer and sent it to be sand blasted so we can cut grind and refit a few things, then send back for powder coating. Wasn't as rusty as I originally thought. The biggest issue was the float bar tube was completely rusted thru. The rest was just surface rust and normal ware for 40+yrs

Day 9 - got the trailer back from blasting to fix, repair and update some items.
Blasting turned out OK, nothing crazy besides the 2" float bar beam which we knew was rotted out.
Made some inner fender liners, cut off the tongue, replaced the entire tongue and float bar with 3", added 1-1/2" down the center (just for extra supports, not really needed).
Raised and modded the bunk mounts 1-1/2" up, the jet intake was hitting the support bars WTF! this will also gain some fender clearance.

The trailer was four pieces (which I assume is typical for this type of trailer), well we welded it all together as one and added the center support for additional strength overall.

Next is to get new parts for all the axles and figure out paint. i was going to powder coat it but thinking of just epoxy paint due to some of the issues we found and how ugly the power will look in spots since we can't smooth it out without some bondo filler.

Also got new fuel tanks. Mine were 10gal 48" long, new used ones are 12gal 60" long. Had to repair some pin holes from previous rubbing.
