Running through all the threads about the 4 cylinder engines, there was a mention of "Michiganmotorz" and the availablilty of a new 3.0L engine. After calling them I still have a few questions for someone out there to clairify; does/did anyone ever make a cross flow head for this engine (intake & exhaust on opposit sides of head)... would this engine work in a car, even though it is a marine application...are there any aluminum dress up items such as valve cover, side plates, water pump... is there a rear sump oil pan that would fit this block in order to install it into a model A' coupe? Any help or possible direction would be appreciated. Regards, Steve
Steve, Do they have a web site we could look at? Can you post some of their advertising? My guess is that it is the 3 liter industrial engine from GM but without a picture that is really going out on a limb. Marine cams are different than car cams (or so I was told per a car person I trust). I think I have a marine cam in my car and am not really happy with it. There is probably a good chance the cross flow Ansen head made in the sixties and a new racing head from Austrailia would fit but again, let's see some more information. What head gaskets does it use, that might be a clue. Charlie Stephens
I Googled the name and found this: MichiganMotorz.com... "Your One-Stop Engine Shop!" I haven't poked around on it yet, but there it is.
That sure looks like the 181 inch Mercruiser Marine engine in my '32 Ford, right down to the "HECHO EN MEXICO" on the side of the block. You might also ask your local Chevrolet parts department about their 181 inch industrial engine. I think the newer industrial engine is fuel injected. Check the posts as there has been a ton of posts on these engines. The main thing I like about these engines is that a standard speed shop adapter (they used the same bell housing as a V8) will mate them to a '39 Ford trans and installing one in a Model A is easy after that. You should double check what I say as there may have been changes to these engines that happened when I wasn't looking. Charlie Stephens

with the stock PORT fuel injection head you could just makre some fake hilborn injetors,,,make it look like early hilborn mechanical injection

http://www.mercurymarine.com/engines/inboards/sterndrives/tks3l_specs.php Me, I am running and old 153 from a postal Jeep. I just had to grind of the made in Mexico. I beleive the Mexican castings are not as good as the one cast in the States.
the fontana is the engine of choice at the oklahoma indoor midget race,,,real tight track,,,fontanas have lots of low end grunt. the fontana can be made milder via less cam timing and lowering the compression. blown up race engines are cheeap,,, damaged heads can be weld repaired, even used race ready engines are cheap when compared to new. the cheap way to go is just get the the high compresion GM cast iron Vortec 3.0, with the 8 port head with factory port fuel injection and install fake old timey machanical injector bases and stacks. put in a better cam,,
This guy is doing a swap of a marine 2.5L or 3.0L. Seems like he has done a lot of research. His posts can be found here: http://forums.amceaglesden.com/index.php?topic=38412.0
I know this is an old post, but can anyone tell me if a rear sump pan from a 153 will fit the pre 1989 2 piece 181 bottom end? Thanks
Expect to pay through the nose for anything that says Marine Engine on it. You can probably buy a 350 crate motor for less money. If you want the Chev 4 cyl industrial engine, a lot of them were used in fork lifts. They typically ran on propane which meant they stay clean inside and don't wear fast except maybe the valves. There is a fork lift in a local junk yard right now I bet you could buy the engine for $100 bucks.
