Will do, Sorry for the confusion. Just trying to get the widest dissemination.
Hi Guy's going to look at a Hemi today. The block casting shows 1619829 for 354 and the stamp has an M for marine however is is stamped M35 4-2020. Any ideas? The only reference I can find for marine are all M45-- The head casting number is also 354 but no water outlets, I thought that was only 331 heads? Please see pics below.
The Marine, Industrial & truck engines are like the 51-54 car engines, heads, oil pan, ect. What intake? tuck & marine are different from each other & from car intakes.
The engine doesn't come with an intake. Everything is disassembled and I believe it is a mix and match of parts. It comes with the block, crank, rods, pistons, 2 sets of heads, 2 transmission adapters. When I go look at it I'm going to get casting numbers off everything to see what I'd be in for if I buy it.
No real mystery. The photo showing the end of the cylinder head clearly shows the truck 'pad'. If you remove the spacer gizmo on the intake rail you should find the tall water passage at the center where pass car heads have exhaust passage. The 'spacer' on the front is typical of the truck water pump being raised up a wee bit to get the fan higher.
Why would a 354 block need a spacer?
Someone was probably making a manifold.
Being an industrial engine it may have gears for the cam timing instead of a chain.
My contribution, others with more knowledge can clarify.
Agreed, likely a u-fab project.
Trucks usually had gears but nothing shows in the pics and a pass-car cam is the usual cam used.
Make sure there is a car/truck/industrial crank in that mix.
Dedicated marine cranks are ever so slightly different, necessating a trip to a crankshaft shop, to fix it.
On a land going vehicle, there is a slight step in the snout for the timing chain sprocket. It is not there on a dedicated marine crank.
They run their drive on the "front", and all accessories are gear-driven.
A good crank shop can make the step "appear" there.
Hey guys! Long time no Hemi posts. I'm definitely behind. So behind that even my signature with the banner and hot link to the Hemi Index has evaporated.
@ekimneirbo scanned and posted a great article, some of you may be familiar with, in its own thread. Have a look! Adding it here under this topic. Thanks to him for his efforts to keep the Hemi Tech flowing...
