Found this site while looking for rebuild parts. I have a 1978 Glastron/Carson CV23; 429/Berk JE. Originally had a 460, but the PO replaced it with a 429 because someone told him a '78 460 only had 225hp. He didn't take the best care of it, and it would only spin an A impeller ~4100rpm so I knew it was tired. I was hoping it would get through this season, which it did; she gave up Labor Day. Stuck #3 exhaust valve, broke the pushrod, bent #3 intake pushrod, spit up both lifters and lost oil pressure to the top end.
Engine is out and disassembled. Will be bumping to a 460 crank, Speed Pro hypers, prob a Lunati Voodoo cam (0.564/0.582 lift, 276/284 dur, 233/241 @ 0.050), 1.73 SS rollers. The original D0VE-A heads will be shelved for now. I picked up a set of D3's that Scotty ported; 2.25/1.76 valves, CJ intakes, exhaust ported, bowls blended, etc. Topping it off with a Stealth 8021, and an Edelbrock marine 750 (
Would prefer an 850 Holley, but found this one dirt cheap ready to bolt on. PO had an Eddy 600 automotive installed, huge no-no). The pump will be rebuilt this winter as well. Hoping for a healthy 450hp float next season.

Thanks!
That's just the no-wake zone, main lake is to the right past the point. Things still that dry in Texas? I heard the water levels have been way down the last few years.

I'd show you a picture of our lake, but I don't have a lens that big. 
Not all of our counties are in stage 4 water restrictions yet but they should be. I think drinking and bathing in water is more important than a clean car and green grass. We have 3 lakes that we rely on for water, the combined water level is about 30%! 
Jet Boat Bob can dress up that pump if you want to go fast.

I have seen more exploded SpeedPro hyper pistons in the form of gravel at the bottom of jet boat pans than any other piston on the market. If you must run those pistons, jet the engine rich at wide open throttle.jtmarten wrote: Will be bumping to a 460 crank, Speed Pro hypers...[/img]
