I remember with Ford 302 351, 2V made good power and you had to spend alot more on 4V to get it to breath better. Then it would slightly out perform a 2V .

As i recall, the windsor 2V was "2 barrel carburetor" and 4V was "4 barrel carburetor". The 4V ports were so big that peak HP was better but everything at lower RPM/less than-than-full-throttle was worse. Both types were 2V per cylinder

lol we are losing our connection! here !! :)

DD not many datsun guys can afford a fezza swap and funnily enough Nick I had a 2v cleveland 383 which ran 13.4 seconds in a full factory optioned xb and quite frankly it scared me and my wallet and that was when fuel was cheap. The guy I sold to went sideways onto a curve and rolled it a handful of times after leaving a pub. That engine was such a beast torque monster my friend ended up buying the wreck and we fit it to his xt falcon that was about 300kg lighter and ended up on its roof at Calder Highway on the way to its first quarter mile outing. The same engine ended up in his cousins boat at Lake Eildon and the owner managed to flip it and almost drown. After it left me the "2v or not 2v" as we termed it was such a freak it was like nothing could tame it or it was surely cursed and angry as hell. I definitely feared it the most and hence it probably took pity on me. It was a detuned Nascar engine with 13.1 compression with about 450+lbs of torque fed by a single 750 holley high riser that vampired like 100km with 60L of quality leaded fuel as I often used the secondaries but with respect not like its following victims which were learned their fates.

D , I remember the old days when only a handful of street cars did 12,s and nothing was engineered or roadworthy. Not like today when everyone slaps a big fat turbo on everything and thinks their a Time bandit.

PS luv these stories , Im having flashbacks of my own.

I bought that car already all setup from a retired aircraft engineer that
had been bitten by the rotary bug and had to cut down on his collection
to make way for new rotary projects, he was already 74 yo back then.

He had the time sheet for his runs and the best he could get was 13.4
his reaction time was not the best and the weight of the body was the
main culprit as well but we thought an xt body with average modified
suspension for going straight and some overtaking duties was going to be
enough vs the XB@`s well developed adjustable multi-link setup.

wrong! overtaking cars on the way while we followed behind the xt
ended him at hospital and few mm from total spinal cord tear.
The guy who totaled the xb was drunk enough to escape injury by
being like water through the incident and then fleeing the scene.

On the other hand turbos have allowed older engines to embarrass
newer high tech machinery. Look at what a turbo a12 have achieved
also older 2jz vs the latest and greatest.

I grew up in the era believing that you cant beat cubic inch !!
I did my driving test at Boronia Police Station in a 300hp HQ.. All I did was drive the cop to the bottle shop and back.
And the 80,s produced some weirs and wonderful concoctions in the world of Sleepers
The cops use to sit in the service lane with us and only book the losers. Haha Mario,s in their GT,s and Ex Interceptors and Skips in their holdens and a few geeky nutty professors
Plenty of average rice burners , brock commodores etc

I wonder what happened to that beast, it sounded like an m60

factory seems to be better than aftermarket
for the rx7 and gtr models

Id love an f3ds but giving it any stick is
like the same amount of fuel used by an
average big rig or road train
