I was wondering if I could get some hints on improving my stock 200 in my '71 Maverick.
Ignition, exaust, fuel pump, radiator to start with. Any simple suggestions for me. If it's just parts, I can install 'em.
And, can I get a recommend on a fan &shroud upgrade?
Thanks ahead of time!
It is just parts.
Modern control systems on an old 200 work great. How far you go in the modernisation process is up to you. Even millionairs have to be budget orientated.
$2500 always gets you 13.5 second quarter miles, even with an old automatic 3.3 with a 400 dollar turbo.
Igntion. Follow
thesameguy for an EDIS6 update.Its the best system you'll get, testimony to Fords smarts when it comes to igntion. Any Duraspark II will do a similar job for a lot less money.
Exhaust. You can get an 18% power gain by fitting a tubing header and twin GT exhaust with an H or y pipe. Problem is a header is mutually exclusive of other things that we like.
The real problem is nobody respects the customer enough to have any headers A/C and air pump compliant. I PERSONALLY wouldn't even consider any header made anywhere in the world. They all require you to remove your emissions air tubes, or relocate your air conditioning pump or even your alternator.
Mind you, a good stock U tube on an existing header could make a 335% power boost with with 13 to 20 psi boost and a T3 60 series turbo. Or T44.
The cheapest exhaust verses hp benefit is therefore
First Fox,
Does10s,
66Sprint6 and
Lincs200's turbo exhaust modification.
Going from a 87 hp 65 rwhp ploddder to a approx 300 hp, 225 rwhp firebrand is just that, a 335% power increase. Still running a C4/C5 auto
Fuel pump. Follow

Matt (
66Sprint6) wrote a post on using the 350 Chevy fuel pump, a M4891 Carter fuel pump with a converted 200 Ford rocker arm as a performance pump. It pushes too much pressure and volume for a stock 200, but with an 804 regulator, it would be fine.
Two options, electric or conventional fuel pump. An 804 holley regulator works with each. Does10s ran an efi pump with a regulator and return line for his 450 hp 250.
Radiator.
64 200 ranchero found an old Nissan Maxima radiator for his early Falcon 200.
Those give you options.
For me, I'd recommend you go for:-
Durapsark I or II igntion off 1975 to 1983 3.3 Ford six.
Get the 1980-1983 Casting no EOBE 9430 KE cast iron header.
Its
1. space efficient,
2. compatible with Air Con,
3. and a lot better than stock 1960-1979 factory header.
4. For the years it was around, it made an extra 9 net flywheel hp over the earlier 2" outlet exhaust, and
5. has provisions for Secondary AIR and EGR.
This was found on a lot of the 1980-1983 Fox bodies, and for one year, the 1980 Monarch and Granada with the 250 engine.
Its a funny looking 4.25" iron exhaust header. If you can find it still equipeded with the "primary light off" catalyst (they are normally stamped E1 BE 211 with a letter suffix A, or E for secondary AIR. On the 1980 X cars [Mercury Monarch/Ford Granada], its E0 DZ 5E212 A or E [for secondary AIR]
You cut the cat up, and have it welded to a twin 2-1/8" outlet header adaptor using two down pipes.
If your stuck for how to do the adaptor, a replacement cat is around from Catco, who still make a #66991 version for 80-83 3.3's and 1980 4.1's..

Duplicate the stock down pipe twice, side by side this way.
A hacked up stock cat downpipe would look like this
