I don't know about other engines, but when searching for a good Ford 427 builder for a muscle project, old boats are usually the cheapest place to find one.

I doubt it, most marine engines spin backwards. Marine engines spin same way as all regular automotive engines do Then why do they make starters for reverse rotation marine engines ?

Because the transom mid housing (transmission) spin opposite directions not the engines

usually I don't like to get in the middle of these things, and I have only been working on boats about 5 years, but most marine engines are standard rotation just like a car, but a few rotate opposite. I haven't ran across one yet but it seems like the most common application is twin engine boats, but have been told that once in a while someone will decide to put a reverse rotation in a single engine boat.

I've installed a few sets of counter rotating engines in houseboats and the output from the the rear does spin opposite but the engine itself doesn't

Okay I have been reading some of these and let me start off by saying this the saying that the 4.3 is just like a 350 just minus a couple cylinders you are so wrong about the only thing that is the same is the bore diameter of 4.00 in the rods themselves are acutually offset you can use standard sbc rods but you have to have them machinedthe 4.3 is very expensive to build in comparison the distributor yes you can use a v8 but you will have a slight miss in it since it will be picking up on two extra cylinders don't cheap out go online and buy a v6 hei edlbrock sells a nice intake for them for about 275 bucks you also have to watch out for your block you could get one with a balance shaft or one without my first one didn't have one and it was out of a 90 Chevy 1500 2wd truck so there is a lot of research you will have to do on your block casting number also the 4.3 is a even fire motor you can buy a crank to change that but they are very pricey

Does anyone have a pattern to build a full engine cradle with distributor protector and the carb protector. Thanks

Yes I have all the patterns and measurements. Took me a couple days of work.

So I have a 93 Astro with a 4.3 TBI. I was wondering if a fuel pump from a 97 olds cutlass supreme with a 3100 would be to much for the TBI or will it work fine?

OK thanks I was just seeing that way if it did work I didn't have to take the 3100 pump out of my fuel sell. But sounds like I should change the pumps just to be on the safe side.

Has anyone built a 1999 4.3 yet or around that year?

I've got a 4.3 in a 2004 s10. Will I have to buy another intake to carb it or can I modify the stock one? I'd rather run this than rebuild a 250 straight 6 for it as long as I can carb it and get a turbo 350 or 400 to bolt up
