McCulloch BP-399-T

One of the first runs. 399cc 30hp

[@bigtexas7580]

*Damn that's a good sounding engine. Sounds like it has some serious torque.*

[@mweba1]

The story goes, McCulloch built these in order to break into the snowmobile engine market. This is a balanced piston design engine with variable crank case volume. Very cool design.

super bad ass mcculloch ghost engine, nice to finally hear one run, awesome video gentlemen.

[@bobcornwell5046]

Yes sir.

[@altecman21]

Yeah and Wow!!!

[@piroguejoe]

Cool.

[@joeymt3]

30 hp at 6000rpm is what it was rated at I think. When we tached it, itwent over 17k

[@xzantronos]

I was close.. I guessed 20k rpm

[@jonathanwalda811]

That was what I was wanting to know thank you. That little bugger is awesome

[@josh33025]

Nice blast from the past always see the saw king show them but never seen one run. Hotsaw anyone? :→)

[@gadsden1957]

My Father was a McCulloch dealer when they were testing these, McCulloch wouldn't say much if anything about it, my biggest concern was, who made a clutch that could take that kind of speed without flying apart? P.S.-I have 2 BP-1 chainsaws that use the same balance piston design with factory service manual and all of the service bulletins.

[@mweba1]

Good to hear guys like you are keeping history alive! I have a BP-1 waiting for a rebuild/parks.

[@94coryb]

[@ranst4038]

[@mistermacgray]

It was but taken down because his daughter dismt know how to do shipping around the world and havent heard anything since the listing got taken down.

[@generaldistrust]

LMAO man!! :) But just 32? ha haaa.......

[@captainsledge7554]

Keep revving like that without letting it warm all the way up and this one will no longer be a running example.

[@royb.1441]

Yea because two strokes run so crisp and perfect like that when dead cold immediately after startup.....in case my sarcasm was lost on you (bro he obviously warmed it up, 😂)

[@darkx7846]

Im kinda triggered cuz ur redlining an engine that only 4 of them still exist

[@mweba1]

Way more than 4 exist. This gentleman alone has/had three. They show up for sale from time to time.

[@johnwells7931]

makes my skin crawl when I see him rev that vintage engine like that ,, no wonder we can't find them anywhere they all got trashed by some idiot

[@919hornet4me]

Couldn't agree with you more!

[@gadsden1957]

Don't get too upset, even though you can't get parts for it anymore, those old Mac's can take it, my father got 18K rpm out of a Mac-10 set the track record for a single engine class at 128.5 MPH, quite a feat for the late 1950's
