www.fordsix.com has a wealth of info on racing 300s.
Sorry for the long delay in responding, old sparks. Must be an age related problem. I don't know much, but I liked the 7 main bearings as opposed to 4 in the slant 6. TFF is correct, you should scour the fordsix.com site for information. My intent was to build a mild engine so it was easy to tune. Tried for a fair amount of compression by decking the block and milling the head. Used forged 390 Ford pistons, 1.94 Chevy intake valves and 1.6 Chevy exhaust valves. Had a mild regrind put on the cam by Oregon Cams. Used a 750 Holley vacuum secondary carb. and an antique MSD with the points distributor. Harland Sharp aluminum rocker arms and custom length Smith Brothers pushrods.
The Frenchtown Flyer is far more experienced, and successful at building and racing 300 Fords and if memory serves, yo will find an extensive article written by him by searching the ford six site.
Bob, I looked through the fordsix.com site and found a lot of information on small block 6's, not very much on the big block 300 motor in the way of performance or interchangeable parts. Maybe I am looking in the wrong place. Maybe You or Flyer can point me in the right direction. While I have some time to mess with the computer I would like to learn a few things about the 300" motor.
Did you get a set of forged 390 pistons with 4 valve slots from Summit? Did you have any taken off the tops to make them more like a true flat top piston? What kind of CR do you think you ended up with. What size cc head are you running. Is the block -0- decked? When that next test & tune?
Did you check the 240-300 section, also read the 240/300 FaQ section lots of good info in there. Clifford and Offenhauser still make intakes but you can usually find them on ebay or at the swap meets for less.Here's the FaQ
Bob, sorry for jumping your thread, only trying to learn a little about the Ford 300 motor.
Tom, Don't ever worry about jumping on my thread. Same goes for you, old sparks We're all friends here. If you go back to page 30 of this thread and work forward a few pages most of your questions, and all of the answers that I have about this engine are there. The pistons were flat tops and nothing was done to them. At 114 mph, my best top speed the engine was at 5,400 rpm and still pulling hard. I would have thought it would run out of breath at that rpm with no porting and the small cam it has.
Bob, thanks for a place to learn about the 300" motor. Went back and read the pages on the thread about the new bullet, lots of good stuff. Did find a lot of good information on the BBF 300 on fordsix.com. When do you test again? Winter is just around the corner in your neck of the woods.
Beautiful weather right now, but it can change fast. Oct 3 is the next date. Could be a nice fall day or it might be really nasty. Let' hope... My block was already .03o over so the 390 pistons were my choice.
Here's an article I wrote when I was a dumb punk hoodlum:
Somebody over at fordsix.com blew it up to readable size without exceeding the size constraints of photos.
Ok flyer, I am old and still not seeing that well from one side, sure would like to read the story but can't make the print fit my senior vision, or maybe I'm getting to old to run the computer. Please a little help.
Tom, click on the red "fordsix.com" below FTF's article and you'll get a readable copy.
FTF, thanks for posting the article.
I am glad to see that the Ford 240 / 300 is getting as much notice lately on here. You will note that stock it came with seven main bearings, 12 port head, available forged steel crank, standard bore of 4.000 inches, SBF bell bolt pattern and other features that make it superior to other inlines of the '60s. I always thought if it were not conveniently written out of the rule book in LSR vintage classes then the record book would be awash in Ford blue. That is why I call it "the best kept secret in drag racing".
I'm about 90% done with this 1963 Land Rover. Working on a couple other projects now. Hoping to run the dragster one more time on Oct. 10th.
I picked the 300 Ford 6 for the reasons you listed, FTF. It appeared to provide the most bang for the buck.
Rover is coming together, would make a great tow package with the dragster. What are your new projects? Sure hope the weather holds for your Oct 10th test run.
There's only a couple things that could keep me from TnT this Saturday. Rain or the sale of the drag strip and its immediate closing. You guessed it folks. The strip was sold and will not be open again this year. The good news is it closed for repaving and other improvements. Not a case of going under.
So, I'm putting the dragster in cold storage (outside, covered with a tarp) until next season.
Tom, I've got two projects going; a Renault Dauphine getting a 406 sbc in front & the '32 Bantam coupe with a 468 Big block, street and strip.
All tucked away for the winter. In 6 or 7 months we'll again be able to race in Minnesota.
That coupe is going to be a great winter project and fun for all to follow as you start building another old school hot rod.
Did some frame building and mock up. I know I should post the build on the main board but there's too many snipers over there. I'll quit cluttering up the HA/GR forum with N/A junk.
If you start a build thread on the main board, post a link here so we can follow it. I've always loved Bantam coupes.
Yeah, what he said.
Me three! You got all the cool toys! thanks.
I'll sneak a progress shot of the Bantam in here. Don't tell anyone.
bobw, don't worry your secret is safe with us!
Your secret is safe over here in Australia too. Keep going.
The rear end is narrowed, front and rear suspension is done and I'm working on the roll cage.
Well Bob, it looks like the ol' bullet has struck again! While cruising through some drag racing sites I ran across this one:
In the index is a link to a story about the Meltdown Drags. In the article are two scrolling group of pics. In the second one is a great shot of you flogging the bullet down the strip.
I'm getting so famous I'm gonna set up an autograph table, sell T shirts.
