221 engine

hey
i was looking at off set grinding a 200 crank from 79.55 to 93.47
found cant go that big most is about 222 with honda rods thats the nascar boys use.
so no pont when ford makes a 221 engine which has a steel crank? iam lead to beleave.
so if i can chase one of these down then all i will need is the twin cam head us 200forged rods forged pistons and i should have a 9000rpm engine that makes very good power and is a sight to be hold every time you lift the bonnet.
(yes i could just super.turbo or put a jap motor in but i want a project in which very few have done before to learn from)

Re: 221 engine

what twin cam head have you heard of that fits a 221 engine?
I understood that the 221 series was the same as the older falcons up the the XW etc thus the only head that would fit would be a log head or a 2V head. Neither of these are twin cam.
Im interested in further info :)
I think to get to 9000 RPM you are going to have to put a stud girdle into your bottom end which would require a custom sump/girdle combination, which could get nasty..

Re: 221 engine

The 221 crank is not steel..... This has been debated long ago...

Re: 221 engine

hey
the twin cam heads from krogdahl heads.
yeah i found out the 221 were cast just a pretty good cast.
going to have a custom crank made up about 4g machined steel to how i want.
craddel is pretty easy 12mm use 302 win head bolts with spacer's between the craddel and the main caps, will most likely have it bolted to the sump rail as well for more regity, and fill the block with that specile epoxy, and drill an extra hole for oil around the mains and big ends on the crank and block
oh xflow heads fit with a little bit of moding of the block basicly making it wider.

Re: 221 engine

Your engine sounds nuts! good work.. make sure you put some picks up for me!!

If you are serious about getting a custom sump/stud girdle made up, Im interested too.. Never know when one of them would come in handy :)

Im also interested in your custom steel crank. Have you found someone who'll make one yet? What are you budgeting?

How much are those Krogdahl heads worth??

Re: 221 engine

waaaaaaaaaaaaaaaaaaaay tooo much rooting around for me... why not put that development work into a 4l engine, then you would be starting with a lot more refined block etc to start with

Re: 221 engine

Sometimes I think the same thing, but at the end of the day, I think putting a newer engine into an old car usually doesnt look right. In 10-15 years time it'll just look like someone's butchered the car.

I feel, a tastefully modified original style engine will always look the part...

Thats my 2c worth anyway :)

Re: 221 engine

hey
because the newer more refind engine is still based on the 86da black from the xflow and for a stop gap will have a ef crank with the extra counter weights so its not more refind just less capacitybeing 1mm smaller bore for better emssions
about 4 grand for the steel crank from the looks of it.
i thought about a ba 4l with the 4 valve head etc but dont lie the way the cams are dosent look like i could put massive 290/300deg with 550thou lift
about 5.5 g

well, you may aswell use a 30 year old engine then since is so much the same... ONYA, i did happen to say block ETC was more refined, namely the lack of pushrods (he is wanting 9000rpm) the flow potential of the head, if using an au engine, he will have a factory stud girdled long rod engine... i know which one i'd invest money in

Re: 221 engine

hey
pushrods ummm mabey i could weld some in the sump considering the krogdahl heads are twin cam conversion for 250 xflow 202 red etc
so ill have a head that will flow 500+hp and ability to rev.
the engine will also be in a te cortina meaning i will have to make a custom sump up from the au one looked into it cheaper to make a sumpcradel and stud cradel my self then convert a alloy au/ba sump
other reason i dont like the ba twin cam.
the only other advantage of the latter blacks is slightly lighter but dont reall concerned there will make taking weight off everything inside the engine not the block.
basicly there is not gojng to be much ford left in the engine block mabey a crank and thats about it.
