Holley 950 vs FST 750 Carb: 347ci Ford Maverick Dyno Day

Hello helloooo! We're back at Addiction Motorsports to dyno the street car and test out some carburetors! The car currently has a 950 cfm Holley carb, but we have two different FST 750 cfm carbs to test out as well. Stay until the end to see how Tony leans out the air fuels in his own way!

No one would argue that Bill Hoskinson knows carbs however,, Tony has been break'n hearts in Cali long before they knew the Hoskinson family. Tony knows his way around a carb too.

[@wvhillbillymike9302]

Ok....I would like to know Tess’s background on cars/mechanic’s etc. She is entertaining to watch and listen to as she works on her car and banters with Tony. Not at all annoying. And I mean this with utmost respect, then like some of the shots a her in car and its like that woman is absolutely beautiful. Tony you are a lucky man

[@jordannorman1314]

She's a fake blonde with no skills. What do you think dummy?you think that gal only wears yoga pants for the melon head hubby with gonzo nose? She's using dudes here and there along her way. She not using any smarts to fix anything. She just gets filmed when she does. Even the bell pepper nose dude has no idea. That gal gonna leave for someone closer to daddy.. she will stay with that dude forever. He's famous

[@MissMidnightMaverick]

@Wv HillBilly Mike I grew up building pre-runners and Baja Bugs with my dad, but turned to drag racing in high school on a field trip to Pomona Raceway. Started building my black Maverick 10 years ago and just kept pushing it to the point it was before the crash.

[@johnkorotki7861]

I have FST carbs on my small block 55 chevy as well as my big block 70 SS Chevelle. They both work perfectly. The quality control and finish on these carbs are second to none and the customer service is top notch. With a little more testing and some fine tuning, I'm sure they will get these carbs dialed in. Thank you guys for the great content. It's great to see you working on your own cars and not farming out all of your work to other people and shops. Have a great day and keep the videos coming!

Adjust the 950-properly tuned it will eat the 750's lunch!-Try to lean out the low speed air bleeds-since its rich down low,but straightens up-(or maybe try a different power valve)--Leaning out a carb for power is an art-takes a lot of trial&error,& a BIG box of jets&air bleeds !!!(&a buncha fuel!lol)-Best o luck guys!!-Love the videos,keep em comin!!

[@darringrey4329]

Couldn't agree more , alot of people get scared when it's lean .

[@alltherpm]

Secound time ive seen. Smaller carb win, 4 the big headed carb guys

[@darringrey4329]

They didn't tune any of the carbs?

[@attitudeadjusted9027]

If you'd tune that 950 you'd love it and it woulda made more power thru out and be streetable. We run a 1050 on our 347😎

Very educational video Tess. Now I'd love to see you throw a Holley efi kit on it with port injection to compare the difference, I'm pretty sure the efi will pick up some torque down low. Only if Holley would sponsor one of course lol ! it would be expensive.

Great job you two, were any of the carbs you tried custom done to specifications of the engine combo? Next time play with the timing to see if there's anymore additional power to be gained. You two are a great couple glad to see you work together.

[@MissMidnightMaverick]

None of them were. Haha. We should have fine tuned all three before going to the dyno, but we didn’t get the two 750s until the day before we were headed to the dyno, so we just didn’t have enough time.

Have yall tried a Twin Blade yet? You will like it, pick up power and DEADLY consistent. Contact me or Tony Morris of TMC in florida , Parr performance carbs here in Texas or, little ole me in Texas. Its a Bo Laws design perfected by his son Mike Laws. Bet you a hundred we can pick your up another 12-18 hp with a twinblade, if not more. They 60ft better than anything else we have ever used. They get on the booster quicker so, needs less pump shot time, cleans up to target afr quicker so, 60/330 split is better. FWIW

[@fr.rustymatheny7707]

Too rich at cruise needs to be claened up on race carb just as street carb for more accurate jetting across rpm range- the Hp carbs are easily tuned for this on the metering plates - fwiw. Probably already know but- some dont so, wanted to mention it.
