No I didn't replace the cam. The heads are 333882 (1970-1980 350/400) The impeller is a 12/YJ/B. Yes I replaced the head gasket, lifter. rods and heads. RPM's, couldn't say. It did run about 40 mph (according to a friends sea-doo.)
The things I replaced stemmed from a noise from #7 with a knock, possibly a lifter or valve, still have the noise after. Engine also coughs and sputters at full throttle, it has a Quadrajet on it now. Some say they are junk, some say they are the best, I have know idea.
I like the #1 option. It is a family boat, I would like it to run 45-50 mph if need be.

Engine Mechanical / Electrical / Chevy350...what to do?
« on: June 25, 2015, 12:07:59 PM »
I have a 1976 Cobra Jet tri-hull with a chevy 350 and jacuzzi jet drive. The engine runs but not great, I believe it is the original. I put rebuilt heads, new lifters, pushrods in it. It has a knock from the bottom end. Kinda on a budget (I know, I shouldn't own a boat on a budget...) Now, should I rebuild the bottom end or look for a good used to swap with? But then again, you never know what you are getting, could be someone elses piece of junk otherwise they would be using it...right? I have rebuilt the boat from top to bottom (except for the engine), great shape except for the most important part.
Give me your thoughts if you would please...

Engine Mechanical / Electrical / Chevy 350 parts swapping..
« on: January 23, 2014, 10:58:20 PM »
My engine is a 76' 350. I have another set of heads from a 350 (year unknown), and I was thinking about swapping the old crusty iron intake manifold with something newer and cleaner. Won't any Chevy head, intake manifold, etc. bolt on without any issues as long as they are for a 350? Or are there certain years that won't accept "newer" parts?
Thanks
Thanks

It was never wired direct..
However, I might be a lil stupid because I'm not following ... "HEI distributor should have a 12v lead directly from the battery (use a fuse!) and then the "tach" or "signal" wire goes directly to your tach."
My dist looks like the one in your pic. Where does the wire go to, from the distributor "tach" post?
As mine sits, the wire goes from the "tach" post on the dist, to a terminal block, then a different wire goes from the terminal block to the tach "Send" post...
BTW this boat was rewired at some point, because very few of the wire colors are what they should be according to wiring legends I've looked at...
Thanks for you help!

The wire that comes from the distributor labeled "tach", does it go straight the tach post labeled "Send". It is currently attached to a terminal strip (hot)..?

Interior / Hard steering at speed

Over 30 mph, the steering is very hard, very easy at idle and slow speed. Steering cable and helm are brand new. (Jacuzzi jet) Any thoughts?

The needle is stuck at about 1100 rpm's both hooked up and out of the boat. I have 12 volts coming to the tach at the "Send" post. What else do I look for. I checked all the connections.....

It has a Qudrajet on it that came off a good running engine that was converted to fuel injection. Sounds quite possible.......

1. RPM's, don't know. (Yet) Tach not working, checked all connections, tight still not working. Time to trace wires.......
2. Hull speed probably high 35-40.
3. Noise, hard to describe other than "Bogging"
4. Oil pressure, not sure will check next time out.
5. Have not pulled plug out (yet)
Thanks for the suggestions, I will get into them soon.

The end of the oil pressure line that connects to the nipple on the block has a "bulb" on it. Can I cut it off and put a compression fitting on it?

Engine Mechanical / Electrical / Chevy 350 flat at full throttle
« on: October 18, 2013, 04:42:05 PM »
Engine runs pretty good up to full throttle then flattens out, makes more noise, little louder, little rougher, but doesn't go any faster...? It is a 76 chevy 350, with several owners before me, I am not sure of its history (of course).
Also, it has oil leaking from the oil pressure connection. It has the copper tube, any ideas to seal it?
Thanks!
