I have a set of those. They might be exact matches... Are your risers broke too? That I do not have.

After looking more closely at the pictures, mine are not the same. Mine are upswept a bit.


I have some really bad news for you. If the manifolds froze hard enough to break, thee is an excellent cahnce the block is junk too...

Here is what you need to do right now.

Disconnect the hoses for the broken manifolds from the cooling system.

Hook the hoses together in such a way that the engine itself is completely closed off and pressurize the block to about 15 PSI if you can, it should hold pressure.

Sorry for the misfortune. Suck for sure.....

  thanks for checkin on those manifolds GT, finally got them off
 (apparently dinner over-rides any little boat problems around here)
  not being a mechanic, is there any frost plug(s) that would fail prior
  to the block cracking?

A small block Chevy has what are called Welch plugs, not really freeze plugs. That being said, if it pushed a welch plug, your done... 90% of the time the block cracks in the lifter valley and on the front left corner of the block. If they freeze really hard, they will knock a big window out of the side of the block and the cylinder walls.

Go get some dinner for crying out loud. Boats are supposed to be "fun", you cant have any "fun" while hungry.   :-\

I suggest you pressure check the block and go from there.

Fairly generic 350 casting #, used in almost everything, '80-85, and you knew it was a 4 bolt main :thumbup:
Keep with a 80-85 motor if ya can, so dipstick & pan will be the same, & you can use yours
'86 up has a 1 piece rear main, needing a different flywheel/flexplate, small pattern, and driveshaft pto to match. 90 ish up may not have a mech. fuel pump provision
pre '79 the dipstick is on the other side, but have seen blocks with both pass. and driver side dipstick locations
Damn near any sbc from '55 to '85 will bolt in easily
383 or 400 (406) would be a good choice
OR
upgrade to a roller block, for roller on a budget (think ZZ4) pto/driveline change though

gave similar advice...ie 383 stroker & the upgrade to roller a must.      thx again
