My kinda first car was a white 65 Mustang 289 2V, I paid $15. For it. Me and 6 kids pushed it 2 blocks to get it to my mom's house. When I got there Mom said you're to young to buy a car. So I sold it for $40. To another school friend the car needed a battery and a carb. He got it running a few days later with my help. He was 15 and was only allowed to go up and down his driveway. A few months later it got a rod knock.

[@JamesWoodring-mu2iz]

as a long hot rodder. 50 years. my advice to you is dont worry about the hp. unless you are wealthy you will always be outclassed by car owners who have a bigger budget to spend on cars. been there done that, mustangs have always been my favorite . ive been blessed to have many examples in my lifetime focus on the fact you own a classic car . make it what you want but dont think you have a speed demon. jmop looks and a good sounding ride was my aim . youll save money and be happy. good luck my young friend. thanks for the vid

[@FourSpeedFilms]

Thanks! I don’t want crazy horse power but 100 more hp would be perfect

[@MrTL3wis]

[@paulhardman2515]

Very impressive performance! 300hp is just about perfect for a cruiser/daily driver. Sounds awesome and it's fast enough to have fun but not get into too much trouble!

[@FourSpeedFilms]

Exactly

[@thehumancrumb.668]

Especially for a classic. 👍

[@mariek6993]

300 hp may seem ho hum to some, but do the power to weight on a 2900 lb car and it's alright... plus, like you said, 300 hp is something you can drive every day and you won't get eaten out of house and home.... everyone wants 1500 hp until they need to gas it up and maintain it.

[@dr.hugog.hackenbush9443]

300hp can get you into plenty of trouble on a road course..

[@A2J_Tim]

@@mariek6993 I say turbo it and target 600 whp, should still be pretty reliable while being a whole lot more fun to drive.

It sounds very healthy! Really good throttle response. It sings when you let it! Very nice! As always, great video

[@FourSpeedFilms]

Yeah the throttle response is so instantaneous now

[@Jedi391]

That should get you pretty close to 3v performance. That’s really good for a 60’s V8. Plenty to have fun with on the street.

[@FourSpeedFilms]

The car weighs under 3k pounds, so it moves pretty decently, haha. If I had 100 more hp things would be pretty sketchy with my current tires, haha

@@SweatyFatGuy Perfect upgrade like those little blowers they work great

[@SweatyFatGuy]

@@gordocarbo I built a 5.0 with Edelbrock heads in the mid 90s for a guy, and put a centrifugal supercharger on it, then dropped it in his 89 convertible Fox. It ran quite well, almost as fast as my mid 11 second 455 powered 79 Formula. I have a slightly larger version of Big Chief's engine from Street Outlaws in one of my Pontiacs, a 68 LeMans, his is a 4" stroke, mine is 4.25" otherwise its almost exactly like his iron block engine. Mine is getting a 6-71 this year, for science. 7psi would be around 1000hp/tq. Boost makes a big difference.

My first car was a '65 Mustang GT, 289 4V from the factory. I probably already mentioned it in a previous video. Ended up overhauling it and putting a mild Melling cam in it, and AFX headers. I paid $500 for it in 1973. I remember ordering the headers from JC Penney for $75! Yea, that was another world away. I want my current Mustang, a '73 Mach 1 to sound like yours! Gonna take a lot more $$$ this time around though! PS, my '65 was the same color yours used to be (lol) with white vinyl top and pony interior.

This is one of the coolest Mustangs I've ever seen. It's a daily driver and its driven FAST. It sees some abuse and that's simply covered up with green spray paint.... cool, like I said, but i've been conditioned to only accepting pro paints jobs, which takes me back to my days as a mustang owner... a 1965 fastback 289 and a 4-speed stuck in the back of a barn and surrounded by 10 other mustangs... Klodt's Mustangs, in SE Iowa.

[@seanpowell7385]

Did you happen to know the dyno numbers before the FiTech install? Would of been interesting to see that comparison. Sweet video.

I don’t! Although it feels much faster. It just feels way smoother. The instantaneous throttle response makes it a lot faster in the canyons

very impressive power for a 289! There is no way even a bored 289 block give so much power, even with modern intake and cam changed because the engine must breathe. Your heads have been ported for sure, maybe bigger valves.

[@hotrodfeguy]

E-85 will allow you to push cr to 14-16:1 definitely brings more power. But to take full advantage you need the CR up.

[@Slotjunkies83]

I may have to try fitech out on my 66 mustang

[@openhighwayproductions]

Very healthy small block with street manors. Hopefully, fuel economy will increase with the EFI. It would be nice to know before and after since some folks with EFI claim poor fuel economy.

[@FourSpeedFilms]

I’ll give you a review soon!

[@adriankulenkampff6279]

by boring a 289 cui engine to 302 and changing the camshaft plus installing an edelbrock carburator and intake the car performed on the dyno 240 hp at he wheel. Not to forget the magna flow exhaust which probably made some hp.

[@michfish2260]

Love the build. I have two of these cars. Seems like an optimistic dyno. Stock heads suck on the 289, unless they have the heart shaped combustion chamber and ported to the max. 300hp should be good for mid-13s at the track with a good tire, I say take it out there and let it rip for the next video. One of my cars has almost this exact same build with a carb and it runs mid 14s, so probably in the mid 200s at the crank.

[@FourSpeedFilms]

They have been ported but idk to what extent. Interesting!

@@FourSpeedFilms NUmbers seem fine to me. Had a built 350 that only made 270 to the tire and still broke 13s once i geared it

New subscriber...Great videos. I'm really impressed by these Dyno numbers. I'm running roller 302 with Sniper and headers and am only putting around 217 at the wheels. I have a similar intake as well. Are your heads ported? Do you happen to know your cam specs? I personally think 250 rwhp is rather perfect for a stock-ish chassis/rear end. Great job man and looking forward to more vids.

[@2-old-Forthischet]

What kind of gearing do you have in the rear? That makes a big difference too. Now that you have been bitten by the power bug, time to start saving for all the goodies. Maybe a huffer or turbo. Those butterflies sticking above the hood really look cool! Once my son got 400hp to the wheels, his bank account started draining. Keep banging those gears.

Cool video, 255 Horsepower at the rear wheels is not bad. How much compression do you have? What Camshaft are you using? At what type of mufflers are you running, I ran FlowMaster dual chamber on my past 1966 A code Mustang Fastback and they were a bit too loud for me, I wish I could have fit three chamber FlowMaster's. Magna Flow's are also nice sounding, and sound mellow at idle. To use Flex fuel E85 don't you need a Stainless Steel or Plastic Gas Tank so you don't corrode the factory steel one?

I think I met Jeremy at SEMA back in 2016, sure looks like the guy I talked to. 255 is pretty good for a 289/302. I'd feel kinda miffed if one of my Pontiacs made that much, but they are also at least 100cubes larger, most of them are 455s or stroked 400 blocks that are now 461-467ci. Try the E85, you will like the power you get from it, and you will be able to feel the difference.

How do I keep seeing you everywhere SFG? lotuseaters, dating channels, and now 4 speed films.

Your car sounds good even rolling off idle. Almost has a big block deep throaty sound at lower RPM. Does the FiTech make it easy to tune for E85? It'd be cool to see the difference if so. I know some guys re-time when they switch, but rejetting can be annoying. Pushing a button or setting a saved tune would be much sweeter.

[@FourSpeedFilms]

I believe all you have to do is increase the cubic in input by 30% and that’s all you have to do to run e85. I’m definitely going to try it out

Wise decision switching to fuel injection! It makes your car faster, yet more economical. Next upgrade to think of is a 5-speed, perhaps from a Fox Body parts car or whatever fits. Better spaced ratios mean even better performance, and the extra gear will allow you to cruise on the highway more quietly and efficiently.
