How to make power out of my 200?

[Inline6Merc]

I' am new to the forums and i was wondering what you guys would consider for my 200? I have a 1964 Merc Comet with a stock 200. Im only 14 so this is my car when i can drive and i want it to be an every day street drivable car but i also want to have it scream down the quarter mile. So i f you guys could give me any suggestion for parts that would be durable for stree/strip I would appreciate it!!!

Inline6merc,


With our inline sixes the only main problem/obstical to over come is the breathability of the motor. Back when ford was creating these engines they realy didnt have the idea of a street pure power machine in mind. However they did want durability and a long life motor. These engines can make some good power however they wont be like a 9 or 10 seconds on the quarter. So with this in mind the main focus of building a six should be on the cylinder head, fuel input and exhaust output. Now there are serveral opptions in mind, Fordsixparts.com offer an Aussi 250 2v cylinder head witch helps greatly on the power out put of the motor, however the price of it in general and to build it up is pritty high. OR some folks like to chop the log ( fuel intake manifold off the head) And create one of there own however this can be very time comsuming. Another way to go is to use the stock cylinder head but put multiple carbs on it but then drivability comes to play when ur only getting around 9- 10 miles to the gallon. Depending on how much money you are willing to put in the six the sky is realy the limit. Im my mind a six cylinder with a cam, a 2 barrel weber or holley, headers, bigger valves, port and polished intake and exhaust, wpuld make your six pritty nice for what it is. Some good parts supplies are, www.fordsixparts.com, Mike has all the stuff to make your six on steriods. And Clifford Performance Products, who have been in the market awhile and deals with alot of different makes and modles of the inline six, but dont offer as much power for the dollar for our ford inlines as ford six parts does. Hope this helps and welcome to www.fordsix.com


Keep Sixin,

Thanks for the help! I have learned everything revolves around $$$... But i was wondering about milling my head. How much should i mill off, for my application? Should i even mill my head? I have also read about decking the block what is that? I'm going to the big swap meet at hot augaust nights. I hope to find a 250 head, to replace my 200 head. If i do find one im planing on getting a 3angle valve job is there anything else i should do to the head? thanks for the help!!! I appreciate it!!!!!!!

First, a welcome. Hello

Second a warning. I talk too much....

I have also read about decking the block what is that?

decking the block...

Unlike the Ford V8's, the Ford sixes had very little need for a high compression and optimum performance. All American in-line sixes had loose tollerences which had the piston parking way below the machined face of the block.

On old Windsor and Cleveland V8's, its common to have the piston stop a space of between 30 and 15 thou before the top of the block. On the sixes, the piston at the top of its movemnt can park as much as 175 to 30 thou before the top of the block!

This does four awfull things.

1) Lowers the compression ratio = less hp,

2) Lower compression also lowers torque and fuel ecconomy suffers

3) The flame travel at the top of the compression stroke is hurt by the heated ridge left by the pistons not comming up.

4) The squish or quench (cooling) area around the heads combustion chamber, which was designed to improve power, no longer works well with large deck heights. Result is the car is more likey to need higher test gas to prevent detonation. When you shave the block, it allows high compression ratios with no detonation.

Just shaving the head is often a good idea, but cutting the block down so that the piston parks less than 30 thou from the top of the block is very benefical.

Only issue is that a block shave requires a total engine rebuild, or a taller Ford Tempo/Taurus 2.5 HSC or Ford 4.2 V8 pistons to bring the piston up.

A final note. These days, American production engineers are getting into pistons which park just above the machined block. A good example is the Alloy Chevy LS-1 and Z06 V8's. Piston practically massages the head by comming out 6 to 9 thou above the block.

If you want Too Much Information, search Mark P's posts. The guy is an experienced ignition engineer, and has covered how to optimize the 200 with no fancy gear bar a port divider, a few special gaskets, and some secrete ingiton mods.

Mom's the word, I never told you...
