Big Block?

is it just too big or...any chance?

I say it's possible!
You'll need a cutting torch or plasma cutter,
a saw zal
a really big hammer, preferably a 10lb or bigger sled type
and remember the phrase " Hey ya'll watch this!"

it should fit if

What would need to be modified? I did a very rough measurement on a BBC in the junkyard and it was only like 27 inches from valve cover to valve cover. It's tall too but widthwise it should fit in the 944...lol

It's got to be a long motor too but considering there's already a big-block 4-cylinder in there that shouldn't be much of an issue :p

yes it will fit i accually stuck one inside my engine bay that i had sitting around to see if it would fit but their is definitly some modifications that need to be done to make it work.such as steering cooling systym exsaust hood clearance oil pan and of course the massive tourqe that a big block makes would shred a 944 transaxle.not to mention the weight of a bbc.an all alluminum bbc would be the ticket and would probaly live just as long as you didnt do extreme takeoffs.ive built several bbc motors for drag race chevelles and have broken m22 muncies several times behind its brute tourqe.but it would definitly make a 944 scream under the hood just as long as you plan for the massive tourqe that a bbc is capable of

apparently a BBC is 3" longer, 3" taller and 5" wider than an SBC...hmm...lol hood bulge...

Tube frame the front end.

i did a LS7 in one of my 944's . no it does not really fit ! it will kind of sit in the engine bay but forget about bolting any thing up . i then built a tube chassis on a celette bench to keep the chassis measurments the same as the stock 944 . the 951 trans will hold the tork but not for long i then installed a porsche 996 gear box to change that out for a quaife 6 speed sequential last year .
all control arms and the rest of the suspension is not from a 944 but most is from a 996 like the up rights with custom control arms . the body is carbon fiber and fiberglass .
so can it be done well not really if you want to do a BBC then build a chassis for it .
i forgot the tork tube the stock size will not hold the power either it will twist the thing up as i did coming out of the pits . i had to build a totally new one as cuting the old stock one down to mate up to the 996 trans and broaching the end then having it hardend just did not work . the shaft size is just way to small and there are not enough carrier barings and the baring are also to small .

I have measured the 496 in my Suburban, it won't fit in the 944 without major adjustments.

well like i said yes the bare block will kind of fit but not with any thing bolted in it like headers . the fire wall is in the way so that has to be moved . just building a new front half will not really work either as nothing in the front of the car will fit . so at that point you may as well just build a totally new car and chassis along with suspension too as the suspension is not good for the torque and HP the car will be putting out . not even the stock 944 steering rack will work in the car . when i say nothing will fit i mean nothing !
i have over 2000 hours sitting in front of the PC just in the design work .
after the car was all built and you pass GT2 RS porsche's like they are chained to the ground it's all worth it . but god knows how many times i said to my self as i was building the car why am i doing this .
