Bolt on your accessories, make sure it has brass freeze plugs and go boating.
Please don't buy used heads and just bolt them on. You will never get the entire story. I won't even sell heads to someone that doesn't intend on taking them to a machine shop.

Lilred I would like to just use my parts, heads and have everything redone, I wish this wasn't a budget rebuild but with one in college and one is a senior in high school.

Weather looks good for the river run Sunday you'll be driving the TG.

I copied the link because you said it was looking like about $5,000 to rebuild what you have, which sounds about right. So for a couple hundred more you can have a better package. Then you have a block and some other parts you can sell, be ahead and not be worried in April when the machine shop isn't done lol.
Yes I'm very fortunate that I'll have the top gun on loan for the day :)

+1 w/lilred
while you are waiting to install look for a pos boat w/bravo drive on craigslist and replace that alpha while engine is out and sell alpha and any other goodies from doner boat to recoop investment.
Keep us posted good luck

I agree look at other isues before you lay your money cown for a rebuild. First thing I would do is try another gauge as your numbers are consistant. Very unusual for all cylinders to all lose compression. I am usually looking for the spread between highest and lowest as a sign of an issue.

Thanks pantera I was talking to another OSO member and he also suggested doing a leakdown test to double check. So when I do the leakdown I should pull all the plugs and have choke open full. If I am missing something please let me know, I am still learning.
