IMO "big block"/"small block" is a chevy term that has infiltrated the conversations about ford motors. There are just no clear cut lines of separation with fords. It is what it is: a 221cid is a 221 period. (Unless its a flathead 221....)
I did this swap and I was able to use the stock 302 manifolds with no problem. I also shaved the towers.
thats good to know, i've been trying to make my 351w fit for some time now, i'm not a welder but i do know how to work a grinder lol and i just so happen to of bumped into a pair of maverick manifolds it'll prob be next year till i get it working but i'll reply with my finding as well, thanks again:Handshake
CycloneWill, And the Ford Flathead was either a 59A series, or 8BA series, the 59A had a "cast on bellhousing" and 8BA did not. Plus the flathead V8 came in 221, 239 and the Merc came in 255ci. Just thought I would throw that in. Also thought I would put in a picture of what us flahtead guys call a healthy 289ci flatmotor..................in my Model A "PUP".
400 is not a M, and nobody knows who nicknamed the 351m a modified,,, If done right, the 400 will tow them boat anchors down the track for sure! Let the flames flare,,, again
i agree the 400 can be mean but it depends if u get one from the factory thats built right cuz u could have the same year motor out of the same type of car and one will run harder then the other and runs forever unless u wanna go through it and built it yourself
Sportyfamilycar, They are a great motor to build as they are pretty simple, just getting more and more expensive to build and make any HP. With the money I spent on this motor that makes 313HP @5200RPM I could have built a "full boogy" 408ci SBF.......................but the sound is like no other motor!, and the looks from some of young guys who say...................."What Kind of Motor is that?.......................is priceless...............IMHO
