    Known Good head port service for Mopar?

    I have worked with Travis. Owner/operator of Knowltons Thunderheads in East Bethel, MN (About a 45 min north of Minneapolis.) The guy knows his stuff around Mopar cylinder heads and engine builds. I think today he focuses on higher performance aluminum heads and cylinder blocks. But I've been...

    Racing this Friday/Saturday . Free livestream .

    Go ahead and rub it in that it's summer down under. Lol. But good hunting. I'm very sure the cars don't care what month it is. Let the dogs eat.

    Thank you to the Charger forbbodies community!

    Congrats. And with a '68 to boot? Nothing much finer than that party.

    1/4 mile E/T difference 3:54 vs 4:11 gears

    That certainly changes the equation. I know the Passon A855 has a .70 5th gear. Ideal for a 4.10/4.11 rear gear.

    1/4 mile E/T difference 3:54 vs 4:11 gears

    This is likely true if you have RPMs left on the table with 3.54:1 in 1/4 mile. But remember. 3.54:1 is a much better street application gear set. You will likely find your car at too high RPMs for any distance freeway use at 70 MPH.

    Thank you BBody geeks! Guess the ET

    That's a little thin at mile high. 14.44.

    Monster Mopar or bust

    My motto? "If you ain't breaking stuff? You ain't trying!" 4 years back I was making my way back towards my pit. A track offical asked me if I would go down and help a car from near my pit that was broke on the return lane. I said "No problem." After towing to his site I was up near the starting...

    I picked up another sponsor.

    Never heard of them. But your announcement has now put them on the radar for a few more of us? (Which I believe is the point of sponsorship?) I'm sure I have an application to give their products a try. Congrats on your program and growth.

    My '69 440 GTX vs My 2003 Mustang Cobra 4.6.

    I like that car. Or any car that stunned the automotive performance market. It's why I also like AMC AMX? It's build quality really isn't that special. In fact, less then average. But it's performance output back in the day stunned a lot of people. People who first laughed at AMC throwing their...

    My '69 440 GTX vs My 2003 Mustang Cobra 4.6.

    Same. '69. Same color. Same 440 performance package. Same 4-speed. (I sold first to buy a minivan when my 4th child in 5 years was born. 1991) I obviously did what I had to do. But that also obviously haunted me. So kids are grown. And found this guy 3 years ago near Canadian boarder here in...

    My '69 440 GTX vs My 2003 Mustang Cobra 4.6.

    My first GTX (manual everything) weight was 3670 lbs at the track. This GTX has power steering. So add about 30lbs. Very close to Cobra weight.

    My '69 440 GTX vs My 2003 Mustang Cobra 4.6.

    Actually they weight very simular. What is different than my first '69 GTX? This has 28" tall tires on 15" Rally rim. Fronts are same style but 14" rim. This lifts rear about 1" while dropped front end about 1/2" (I believe due to weight transfer difference?) But it REALLY seems to work? With...

    My '69 440 GTX vs My 2003 Mustang Cobra 4.6.

    True. But what is surprising that a stock and mostly original chassis and front-end components can still after 50+ years? I have even pushed faster than this one event. Only lifting because of symptoms of valve float at 6000 RPM. (Stock tach. So one must take it with a grain of salt.) 150 speedo...

    Business Side of Racing

    I attempted this route some 5+ years ago. I even applied for a low interest loan from my bank as part of their Small Business Administration funding. I didn't need the money. I had that amount in their bank.. Just to get things moving with a new LLC. included a 2 year schedule and plan to...

    My '69 440 GTX vs My 2003 Mustang Cobra 4.6.

    Japan did hit while the iron was hot in 80s. They vastly improved their quality control. And produced winners. Almost single handedly started the "Tuner" era. Of course us muscle car era frown on those builds. As the Hotrod crowd frowned on Muscle cars a generation before. I believe it's EV...

    My '69 440 GTX vs My 2003 Mustang Cobra 4.6.

    It is. And was fun comparing the performance with a classic muscle. I have parked both cars at our local pub's VERY small car show. The GTX still gathers more interest. But Mustang holds it's own. I acquired the Mustang more by default. I bought from an ex girlfriend who was unable to maintain...

    My '69 440 GTX vs My 2003 Mustang Cobra 4.6.

    I just don't understand Ford's thinking? They have had winners before. (427, 351c ect..) But then they drop that line. After a short run. Remember folks questioning Chrysler when they dropped one of the most all time successful engines? The 225 slant 6? But that was at least a 20 year run. I...

    My '69 440 GTX vs My 2003 Mustang Cobra 4.6.

    Totally agree. It was cubes vs boost. That Ford DOHC with its cute little Eaton roots type supercharger is a nice small V-8 package that was nicknamed the "Terminator." 10lbs of boost in stock trim. But in typical Ford fashion? They discontinued after a 3 year run. And of course it's not...

    My '69 440 GTX vs My 2003 Mustang Cobra 4.6.

    Not looking to do any upgrades. There is a run on the these Cobras. A $7500 car just 3 years ago. Now going for $15k+ And I have posted this before. I'm very capable of screwing up something that doesn't need fixing? Lol. Either cars. If GTX is going faster? It will be with a different engine...

    My '69 440 GTX vs My 2003 Mustang Cobra 4.6.

    Well. The road is not always available. Only after DOT is done with their testing. But intake is the first place to start. (Except pulling heads) The Cobra has a smaller supercharger pulley and belt upgrade (w chip) that still held Ford warranty. Supposed to kick HP up near 500. About $1200...
