Take him out of commission

All good info. I sometimes have to dump the boat on dry cut grass and want to keep the effort down. I sprinkle the path with a hand weed sprayer

What is the recommended ratio of Dawn soap and water in a hull spray system.

For comparison and calibration of the trailer configuration, I also plan to fab up an inline linkage using the same load cell (and steel) that can be tied into straps/chains and used to measure tension with my boat floating in my pond and pulling against a strap around a good pine. I would suggest u...

Use this product for your intake front and rear areas. It is not likely to push out if your crankcase pressures are high which is a common issue in high output engines. I run 2 breathers on my 406. https://www.permatex.com/products/gasketing/ultra-series-gasket-makers/permatex-ultra-grey-rigid-high-...

Thanks for the response, I will start eliminating some things to figure the problem out. Thanks again A lot of things you can do that no one else can since it's your boat. Blind questions is real redundant, but to answer one: a 2.38 gear will move a prop 14.28 minutes per degree on your timing. a 2...

go on line to your manufacturers and it will all be there.

if they would have had a soft drive on from the beginning you would not have had this problem. Also when the gear box is assembled there is a pre load on the gears and if not done right your wasting money.

And it would also be very wise on ANY aftermarket HEI to remove the pickup coil off the top bushing and drill 2 1/16" holes in the bushing like GM did and then make the necessary provisions in the bushing support webbing to allow the grease to be able to travel freely in the grease well as ori...

50 more cubes should give a bit more power but not sure how much and if is worth the trouble/cost. maybe a cam swap from a e225 would do the trick

See how it runs but I would be thinking about a belt for the power to the jack shaft. It would be smoother and less maintenance/reliable

find a45* elbo or have one made at muffler shop. Should help

keep us in the loop. good luck.

If your going into it that far,,,,, stroke it

There is a plastic liner in side the cable which when it wears through balls up and creates a tight spot which only gets worse.
yes you are better going new.

how many hrs were on those rings?

pictures?

make sure your rubber cap on the pvc tube at the base of the carb isn't cracked or rotten. If it leaks your carb will be difficult to tune. I put a 2 in piece 3/8 of rubber airhose with a bolt siliconed in it to replace the rubber cap.

tubing cutter?

A mirror might help but a walk back on start up on trailer or ? would be better especially in warm weather. I was thinking about a pressure gauge in the cooling system might give indication of the beginning of a leak after you establish a normal operating reading. Just a thought

another thing to check is upon start take a look at your exhaust pipes. the leaker will be pumping steam before a catastrophic failer

Had that happen to me and the boat was 2 miles in rough territory. had to pull the heads out there (fiel repair) and got her going and now problems for 10-12 years.
I would hang on to that 434 sbc good chances it will out perform the LSA but not an expert

If you have good compression than try a 72x34 or go to a pitchible prop . which is the way
