i want to take out my stock 77' 400 and put in my fresh 351w the windsor is out of my 84 ford bronco i think it will drop right in but im not sure

you'll need a transmission.the bell housings are differant.I belive that summit or jegs carries an adapter plate to use bb ford with sm blk ford,and vice versa.
FYI...351M,400,429,460=BB BELL HOUSING
255,289,302,351C,351W3006CYL=SMBLK BELL HOUSING
360,390,427=fe BELLHOUSING.
i left some engine sizes out,but that's the gist of it.

yup,and some may require a additional shim for the tq convertor.ask if anything is recommended for application.
good luck.might be cheaper to get another trans I 'm sure of price.
and the c-4 is all aluminum with removable bell housing,c-6 is big,tuff,damn good trans.aluminum non removable bell housing,FMX has aluminum removable bell housing but center section is cast,the aluminuim tailshaft housing.decent trans but no aftermarket parts to speak of.get a trans cooler.I used a a/c condensor and mounted it under the bed with an electric fan on it.trans never ever gets hot.
