From what I ve been told recently the fit will not be any tighter than the SOHC with the motor mounts in place, and the headers ''may '' get additional mods, and the frame rails will be closed back up,,. There will be a different booster for the brakes, and double tork straps may be used to keep her in place...seawalkersee said:Hmmmmm... I wonder how far up you would have to cut it (strut tower). You see in the pics that the frame rails are cut. You would have to either raise the engine up and have block huggers and or use some sort of old school header that raises up and then exits at the very rear of the head. I think the best bet would be to chanel outside the original frame and run the upper controll arm there, then use the MII setup with a set of coilovers. Just IMO.
The more I have thought about it the less I think the weight would be a big deal. I have seen 50's trucks with big blocks in them with MII anc Nova front ends under them. There is no way a T-bird/Cougar is heavier than a 50's big block truck. And guys have been putting them in that stuff for years, back when all the components used in a Mustang II front end in a street rod were stolen off a Mustang II. Any more a lot of it is just 'Mustang II style' but all the control arms are tubular and adjustable. the companies that make the Mustang II conversion kits put a pretty large amount of design work into things to get all the geometries correct to eliminate bumpsteer and all.mercutio said:Adapting an MII front suspension would be A LOT of work, and those suspensions were designed for cars a lot lighter than ours. I know just about every street rod with an IFS uses an MII-based suspension, but there are a whole lot of things to consider besides just extra engine room (suspension geometry, component strength, etc.).
