you know........it really is an overdone issue! I am not an expert, but having had 2 Cobras with 351's ...the most recent is CHP motor......stroked to the all important...427...puts out 550 hp and 550 torq. Now, I have been around the big's and heard and taken off with them.......quite a few actually.....and no advantage either way....even the sound is similiar.....very similiar....but hey, you need to do the research and decide..
I do, and have, always found that those that HAVE are excited bout that and will brag it up, which is a good thing. BB boys like BB....and SB boyss like their SB's. Advanges of both....not so sure the BB's are all that much more powerful as some say....even the motor builders will tell you so. But, in the final analysis.....they all are fun. I will admit..though, when I see a hood open and a BB there....is pretty cool!! But, when I show mine.....haven't had ANYONE who is looking....go...oh, what a shame!.........with the slight exception of a BB guy!! (had to say it to you BB boys, sorry, just messin)
One last thing......Boyd....and trust me on this, and most will agree, regardless........when you have big hp and torq...and hit the go pedal....won't matter if you have a yugo motor......it blows your hat off, scares the shi$ out of you and others...and your girlfriend has just taken her.......last ride with you!!!!!!!!
have fun.......stay safe..........and go flying.

If I wanted a trunk engine I would buy a truck. If I wanted an engine that overheated on a regular basis I would get a BB, if I wanted to plow into every turn I would get a BB, if I wanted to scrape every speed bump I would get a BB.

You are already going to pay a decent amount of coin for the Roush small block.:p Why not fork out a bit more dough and get an aluminum FE?

Then you can have the best of both worlds.:D

Just have a look at this for example little Volkswagen vs. Suzuki GSXR 1000 on unprepared concrete runway

If you want it to look a bit original, put a FE into a 427 bodystyle kit and a small block in a 289. If you don't care about this, just choose whatever engine you like and build it to your requirements.

This says it best...there are no 'wrong' engines.:)

Stentor,

Not a bad idea, if a Roush is 14,800 how much is aluminium fe? Hopefully the chassis will arrive before next winter, at least I am starting to get sleep again LOL!!

If I had the option to go with a 427 BB or a 427 SB same hp...I still am going with the BB
just something to be said for the ole 427 S.O ...the way it was ment to be

A few months ago Keith Craft was offering 482 ci aluminum FEs for $16,500 (per a post on this site).

You might want to consider this option for $1,700 more over the Roush small block.

My vote is for the ultimate big block:

Come on Bxx1,

Give him some detail.......
OK,
There are small-small blocks, regular small-blocks, and big-small blocks, there are small big-blocks, medium big-blocks and big-big blocks.

..............and then there are REALLY REALLY BIG blocks.

Got it.

The main attraction Cobras have for us is the raw, unadulterated power of a monster motor in a small car. Our big block was built to have respectable HP and torque numbers without being out on the ragged mechanical edge. If those numbers can be reliably obtained in a lighter package, go for it if that's your vision of the "perfect" car.

Even with the horsepower and torque available to us, there are times I'd sure like to have more.

BossCER 03-10-2008 06:26 PM

BDHE,
That really about sums it up.

It should be about "whatever flips your switch".

Big cubes - Big torque - Big block = :D

I was going to write a long dissertation praising big blocks while spewing distain for the impotency of the flaccid (thanks David!) small block. But I stopped myself.

I will just say:

Big blocks are better because they are, NENEER, NENEER, NENEER!!
