The Heidt's M2 or Rod and Custom M2 are both good suspensions.Some claim (Fatman mainly)that M2 suspensionsweaken the design, move the engine up and forward, etc. But the engine weight is placed directly over the crossmember and onto the wheels (whereas the original suspension transfered it to the shock towers and then to the wheels). With the engine mounted to the crossmember there is probalby less weight on the frame rails than with the original suspension. And those who have installed small blocks say theengine positionis the same as stock (if that's where you want it).
This system allows removing the shock towers and really opens up the engine bay. However, unless you are doing a mod motor (4.6L or 5.4L) or big block, it's probably more trouble than it's worth. The 351W should fit in the stock engine bay without problems.
I put a Heidt's in my 65 to make room for a built and blown4.6L Cobra motor (and I wanted rack and pinion, discs, etc.). It is not hard work, just time consuming and you must double check all the measurements. I bought the kit from Tim's Hot Rod (Wash. state - ibuildm on ebay). Great price and service - about $200 less than anyone else I could find. Here are some pics with my mock-up motor:
Thanks for the help guys. Ozarks06 you bay looks amazing, I love the setup!!! It seems that the work is worth it. How does it ride and handle? The more room for the 351W the better. That way I don't have to bust my knuckles changing plugs.

If you are just looking for a little more room for working on the engine you may want to consider notching the shock towers. If access is all you are looking for then this is a wole lot cheaper than going the mustang II route. Depends on what youa re looking for. Here is a link detailing how to notch the towers:
Theres many a mustang 2 kit or http://www.griggsracing.com/index.php which will handle good also http://www.rrs-online.com/ sells coilovers and shock tower notching kits.You dont have to notch the shock towers both a 351w and 351c fits but its a little tight.I wouldnt use the mustang 2 one its got ackermann problems and puts more stress on the frame rails insted of the firewall the way ford designed these cars.If you do use the mustang 2 kits make a support bars going from the front of the frame rail down by the radiator support cruved up to the firewall.
Depends on what you're going to do with it. If you're going to autocross or something that will put a lot of hard loads on the suspension, modify the stock suspension or go Griggs. For most drivers, the M2 will provide a vast improvement over stock handling (some on VMF who have done bothsay superior toa modified stock-type suspension). See the Reenmachine build. This car was featured in Mustang Monthly this month. http://www.reenmachine.com/67_conv_2006.php. Again the main reason to go M2 is to open the engine bay. If you don't need the space for a mod motor or big block, notching the towers would be much easier and quicker, not to mention a couple thousand cheaper.

Be careful about the RRS notching kit. I believe that this kit is for use with the RRScoil-over suspension. It makes a deeper notch than the link I gave in my previous post. The link I gave shows how to notch the towers while still using the stock suspension. If you go the RRS notch kit I think you are going to have to use their coil-over set up. I may be wrong and you might want to check with RRS to be sure.
And just for the record, you do not need to notch the shock towers to install a 351w or a 351c into a 65/6 mustang. Does it help, sure you can make an arguement that it makes changing spark plugs a little easier but both motors will bolt into the car with correct swap headers and motor mounts. Between the 2 the 351w is easier to install overall.
I have yet to bust a knuckle changing spark plugs, I simply use a spark plug socket, a 90 swivel and two extension arm. I don't even have to bend over.
