FMX handling power

Good day all
Just wanted to know people's opinions/experience with FMX boxes.
How much power can they take? Are they a reliable, strong box?

My 69 XW windsor has one and wanted to know how good the FMX was before i go building a big motor.

thanks

sam

Re: FMX handling power

have no idea on how much power they can take but i know that they take a lot more pwr away from the engine, becoz they're such a big box it take a bit more hp to turn it, howeva i've heard that they're much stronger than a c4 or c10 in standard form wif all the gud bits dunno what the diff will be between the boxes.

Re: FMX handling power

Agree with ziggs - they can handle a stock 351 nicely but any more could be asking a bit much. They are also bloody heavy, and hard to get parts for. A modified C10 is a better bet, and the parts are much easier to get. Not a lot of aftermarket stuff for the FMX.

Re: FMX handling power

Well i recently hooked up an FMX behind a 502 bigblock stroker for a friend and it is going great for the last 8 months and will do for a while yet. This is for street use on street tyres though.Sticky tyres and race use might be different. It handled the clevo before it with a blower and 5 lb boost.
Weight might be an issue but it is still less than a c6

Quite srong up to a point but if you have power then save the 25hp the box wastes and get a C10 , C10 has bigger clutches to my eyes . and the box is lighter , I have installed an Fnx alone but left a lot of washers on the ground :_)
