sorry to bring up an old topic, but i just got here and felt that it needed to be said
there are many, many things that can be done to the big six ford, as has been said earlier, the 300 is a torque machine and with a little work it can be made even more potent
i mainly hang out at a Fordsix forum, and i wrote a FAQ on basic mods not too long ago, here's a couple snippets to get you started, if you'd like a link to the FAQ let me know, you'll need to register in order to view it though
Q: how can i get more HP out of my 300?
A: the easy answer to this is to get the engine to breath better, the main thing these engine suffer from is a lack of air. Exhaust, and upgrading to a 2bbl carb are some of the most common first mods
this is a quote from a member of FSP that dyno'd his engine
The hp/tq was done on an engine dyno at the tech school I went to about 6 years ago, the 300-6 was my engine rebuild project. I had the belt on it spinning just the alternator and waterpump.
330ft-lbs. @ 2400rpm (if I remember right) and over 300ft-lbs from 2000-4200rpm. It made 240hp@4200rpm also. I lost the dyno sheet when I moved about 3 years ago along with other important papers
My complete engine build is.
-83' 300-6 block
-bored .030 over
-cut .019 off the block to get zero deck on the pistons
-Compcams 260H with 212* @ .050 lift .447 lift.
-cleaned up exhaust ports with mild bowl work (done by me)
-port matched offy C to intake ports and some valve unshroding
-Stock valves with compcams springs
-shaved .010 off to clean up the head surface/up compression
-Offy C intake with edelbrock 500cfm
-hooker supercomp headers 1 5/8 primary 2 1/2" collectors
MSD ignition 6t with 2F coil and .055 plug gap
I think thats it, The welding students at the votech had to build an engine stand so I could dyno it.
ran great on 87 octane, my compression ratio was just a touch under 9.0:1 calculated. The .040 quench really allowed alot of timing advance, I ran 14* base timing with 87 octane and stock timing curve. It didn't like running stock plug gap with the stock duraspark and I think I was experiancing spark blowout, the MSD box fixed that.
*note* this is an engine dyno with bare essentials needed to keep the engine alive, the stock 300 had approx 115-120HP, with around 145 HP for the EFI engine
Q: who makes and sells parts for our engines?
A: just about everyone sells parts for our engines, you should be able to call up just about any big name company and get parts (Summit, Performance Automotive Warehouse, etc.) just because it isn't listed, doesn't mean it isn't sold there, call them up and ask them
as for who makes parts:
Edelbrock (Both it and the H-M piece are out of production and fairly rare)
for mildly built engines, the EFI manifolds work wonderfully, and are much cheaper
All these are off the shelf items that are currently or have previously been manufactured. I'm sure its not a complete list and it doesn't have PN's associated with them, but oh well.
if you cannot find anything anywhere, try eBay
, or Google
, they are your best friends, trust me (although eBay is an evil lil demon that'll take your money if you aren't careful)
and i'd advise against going straight to Clifford Performance to get parts, they make good parts, but going by posts by everyone else at FordSix their customer service, prices, shipping, and pretty much every other section of their company leaves something to be desired
they used to be very good about all of the above, but in recent years they've seriously lost track of their roots
