347 Dirt modified

Warm up engine to check oil pressure and tune.

[@angelsanchez3074]

This engine sounds great the throttle response is amazing.

[@shannon5373]

Sounds like popcorn is popping in those headers. Nice and crisp!!! Sounds F'n amazing

[@BrainyThyme3869]

Sounds like my 358 SBC dirt modified. Nice!

[@omniewolfy]

What a nice engine

[@southernheritage8740]

It’s bad ass man! Love it

[@petergehle4222]

Used to build dirt modified engines in Australia. Mainly 350chev. Cast heads 10.5 to 1 . Dyno between 560hp to 600. Cool

[@Jay-fb2lv]

Nice engine

[@hankroberts-mi3yd]

Quick. Nice build!! How did you do??

This needs to be my ring tone on my mobile phone! Dale's Auto did you run this motor in your modified?

My Mechanics raced it in there car

[@mrslurm724]

engine was in a imca mod now in a bracket drag car check out [mr slurm [for other builds

[@time8533]

Man that engine sounds killer.👍 if I may respectfully ask what's the LSA

[@jasonsardie8085]

Small cube dirt track engine with a 250@050 split or square pattern cam spec. I would imagine 106-108 lobe centre. Especially if it for a short track. Just a edmacated guesstimate...

[@time8533]

@@jasonsardie8085 yeah I was just asking because I'm building a small block with a 264/268 @50 .667 lift on a 105 LSA. it's actually a dirt track camshaft and I was trying to find something that someone was running clothes to my specs so that I can compare the sound.

[@jasonsardie8085]

@@time8533 that's a nice, very tight cam shaft. Depending on the size of the engine. I would put a can like that in a short dirt track 350-370 cube carburettored methanol 13-14:1 comp. Solid roller, 7500 red line race only engine. Who ever is doing your engine , I would suggest that when it is ground, it is ground with 2-3 degrees advance on in. Just to help widen the torque curve.

It's GOING to be barky !!!

[@time8533]

@@jasonsardie8085 yeah I build my own engines I kind of have a small machine shop in the back of my house I do machine work and racing engines for some people I just had this camshaft and was kind of curious what this guy was running to compare sound out of curiosity

What’s the cost to build something like that?

I can smell it lol

yeaaa that's nasty

What compression

[@smalltownplaya712]

is the advantage of running a 302 block vs SBC weight savings and flatter torque curve of a wider LSA cam in a 347? Also, what heads and compression on this beast? idk much about fords. thx

[@mrslurm724]

351n ford heads, probe dome pistons cut to fit cylinder head, comp around 13.5 to 1, and weight is lighter however depends on the chassis and the weight above roll

[@boxman-x]

How much compression?

[@Kevin_Knox]

yeah the one number I wanted to know (compression), he never mentions. But its gotta be high.

[@mrslurm724]

@@Kevin_Knox 13.2 to 1 pistons have a small dome

[@ericfitzpatrick5319]

what's the cam lift?

[@talltimbot]

It has squeeze so needs methanol

[@jeffswann2842]

what gives the throttle such a tight rev ?

[@anthonymilano691]

Compression In conjunction with a rev kit, Plus most dirt cars have no weight hanging off the back of the Crank

[@CL-ty6wp]

Its not turning a trans and drive line

[@josephtalarico1749]

​@@CL-ty6wpeven hooked up to trans and driveline they'll rev like that... it's light rotating assembly and super high comp like 14.5:1 to 16:1..... outlaw late model motors are 2nd to none... 65 to 80k

[@fullsendsornosends1176]

Im tryna figure out what makes the throttle response so snappy like does anybody know the answer?

[@MichaelMcCaulTX]

compression

[@strokerace14bp]

Lots of things attribute to crisp response but no converter or big clutch hanging off the flywheel is the main reason. Internally balancing the rotating assembly,lightweight clutch assembly amongst other things is a must 4 that kind of throttle response.

[@burnychaplin4601]

Oval outlaw is 100: percent correct no weight on crankshaft just a starter ring and maybe a light weight coupler or most dirt car engines and a Sprint Car doesn't even have a flywheel or starter or battery that is where you get that wap wap insane throttle response you can take an old Chevy truck or car with a v8 and dual exhaust un bolt the torque converter slid it back into the pump on the transmission that's all your weight fire it up and it will sound bad to the bone with nothing but the starter ring on the crank but you can't drive it that way LOL

[@jamestone265]

No flywheel.. starter ring gear. Dirt Modifieds don’t allow roller cams anywhere we race…
