A Ford owner who suggests a GM engine. Have you had any problems with the engine on your van???? You've not heard it all quite yet... I still bleed Mopar once in a while. I've not had any problems with the V10 other than regular maintenance issues. I've had to replace the water pump and need to replace the alternator in future sometime. These engines do have a weak spot - spark plug threads that are easy to strip out. I changed the plugs earlier this year and, knock on wood, have yet to blow a plug. Wasn't easy, mind you... As for a Ford owner recommending a GM engine - when one is looking at doing an engine swap, simplicity is worth its weight in gold.

So would you recommend a GM LS over a Ford modular V8??? | | | Re: Engines - Ford vs GM | Joined: Feb 2011 Posts: 12 stranger | stranger Joined: Feb 2011 Posts: 12 | As for a Ford owner recommending a GM engine - when one is looking at doing an engine swap, simplicity is worth its weight in gold.
So would you recommend a GM LS over a Ford modular V8??? I don't recommend either of them. Both engines cannot run without a ton of electronic controls. When doing a swap like you are considering, computer controlled engines means a lot more complexity which, in turn, means a lot more money involved. Before you dive into a Ford Mod motor installation, you need to take lots of measurements and check the physical dimensions of the engine. These engines are large and complicated. There's a reason you see tons of LS and previous generation GM and Ford small blocks in hot rods of all sorts, but very few Modular Ford engines. If I were in your shoes, I'd be looking at the 351W Ford with C6 automatic.

I was wondering whether I should be looking in Roush's catalog too. | | | Re: Engines - Ford vs GM | Joined: Sep 2010 Posts: 360 enthusiast | OP enthusiast Joined: Sep 2010 Posts: 360 | I was again searching online for more info and came across this link... http://www.camaroz28.com/forums/showthread.php?t=472223 Over there I saw the following quote.... Re: Modular ford VS LS1 Gm powerplants. Well first some of the advantages they do have over our motors. 1: no noise at idle and smoother running engine. 2: better gas milage in stock trim and modified trim. 3: less maintanance when it comes to the valve train. 4: Less compression stock which enables better boosting. 5: Overhead cam ability which enables high RPMs.
Advantages of LS1 motor 1: Cubic inches over fords modular 346 to 281. 2: more compression to help the NA guys (like me) 3: Great flowing heads and intake, unlike a mod motor an ls1s intake flows well. 4: Great bottom end that is probably stronger then your adverage 281 Gt motor (unless compared with cobra motor) 5: more aftermarket and cheaper parts.
These are some things i can think of right off hand, although i must say a 4 valve head on a cobra motor makes exceptional flow over an LS1 head. I have seen 320 CFM out of a 4 valve head, and i know that it is capable of more. This is a limiting factor with LS1s, even know they flow almost as well with half the valves i dout that they could ever flow as well as a 4 valve head. Anyone have any ideas yet? ... and this guy is a GM fan? | | | Re: Engines - Ford vs GM | Joined: Oct 2002 Posts: 3,601 Likes: 10 pooh-bah | pooh-bah Joined: Oct 2002 Posts: 3,601 Likes: 10 | A modular engine will NOT fit in an older van, they are much too wide, the newer vans went through serious tooling to fit them, they are set forward to allow room in the passenger compartment. Yes they have a lot of wiring and electronics, but are far more efficient than the older engines, but I'd go diesel if I was serious about efficiency and power. Dad's neighbors son graduated a tech college, they had to build a diesel before graduation, I'm talking design one, he worked with Ford on fixing the 6.0 and 6.4 that replaced it, got me wanting a smoker. | | | Re: Engines - Ford vs GM | Joined: Sep 2010 Posts: 360 enthusiast | OP enthusiast Joined: Sep 2010 Posts: 360 | Newer engines do have a lot to deal with; but it is agreed that they are more efficient. Reliability is another issue. We know that the older engines use more tested and tried technologies. If space was an issue and I wanted a newer engine design, I'd probably would have to go with a GM LS engine. God knows they're a bit more simpler to deal with and use the old pushrod technology so they're obviously smaller in size. Could be worse, I could have opted for an engine off a Toyota Hiace. Those are the same size as the stock VWs, practically indestructible and reliable to the ends of the earth; but I wanted something that sounds much more cooler.. ;)
The VW stock uses a 2.0L 4 Cylinder diesel to a 2.4 inline 6 Cylinder diesel. I was hoping to swap the diesel engines for petrol V8. I wanted to use a V8 from GM or Ford because their reputation. Choosing between the two however is a hard choice for me.
