My engine compartment has been extended 13inches. So my question would installing an engine in the longitude way, be better since the weight will slightly shift towards the middle? If so will this give me more options towards engine choice? Which engines?
Others will probably know more, but staying transverse will probably give you more engine/transmission options. Longitudinal transaxles are fairly unusual - you'd be looking at high end stuff (Ferrari, etc.) or re-purposes FWD Audi or converted Subaru stuff. You'd also have to consider control issues, since you'd likely be looking to control a transmission designed to sit in front of the shifter from in front of the gearbox. None of this stuff is insurmountable, but compared to the selection of cable-shifted transverse transaxles you're definitely limiting options. OTOH, going longitudinal probably gives you access to physically larger motors (ie more than four cylinders "long") and may help weight distribution and may improve your ability to put down power (equal length driveshafts). Costs notwithstanding, I think longitudinal is certainly sexier (see the "Audi A8 My Fiero" thread), but its performance benefits are probably outweighed by its costs.
A flipped Porsche G50 transaxle can be mated to just about any engine, Kennedy makes quite a wide range of adapters. They even have one for 1st and 3rd gen Viper V10 engines. http://www.kennedyenginc.com/Pages/default.aspx
well since you streched the car 13 inches longitude install will be prety easy as i have been doing it with an audi v8 with out a strech. for a transmission you will want a 01x out of a Audi if you want the stongest transmission then after that a 016 but with a 016 you need to do a pinoin bearing plate . i am running 012 it's cheap but not realy strong
For 5spd options, longitudinal is much stronger. Unless you drop 6k and do an Nsx trans.
Going to drop that much or more for the G50 plus parts to install, G50 alone used runs $4k+ but the longitude is sweet , I have thought about it myself but not the knowledge nor time to take on that task,, ------------------

If you are stretching the chassis that much, then I would go longitudinal. If you don't, there will be a huge gaping hole on the front side of the engine that will look out of place.

I filled that huge gaping hole with a turbo, intercooler and intercooler water tank. Worked out really good. I agree with the other posts.
Well, you can use a Th-325, or a Th-425 (both from the El Dorado / Toronado). They are extremely durable transmissions and work exceptionally well... but, they're both automatics. But... limited slip differentials are really easy.
Longitudinal set ups will take a lot more power and abuse than transverse ever will. If you want to go with a big hp v8, go longways....if its just a fun driver, go sideways...cheaper and less work.
Can you just connect to the rear mounted corvette transmission and use the whole corvette rearend? If it would fit that would be awesome. Imagine if you will a SBC mated directly to a corvette rear transaxle and suspension.
Got to be cheaper than a foreign gearbox and parts pricing is no comparison. Plus you get a very well designed rear suspension.
Corvette transaxles are extremely long, as IIRC they are a standard rear differential with the front piece removed, bolted to a transmission with the tailpiece removed, more or less.
Most other longitudinal transaxles have the "transmission" part of the transaxle mounted behind (-ish) the axle centerline.

Yes but an audi transaxle isn't near that. I've purchased them before for $500 low mileage.. Not to mention they are damn beefy transaxles, twice the size and weight of a Subaru one I had sitting next to it.
Not sure if you can get one FWD only, or how easy they might be to convert, but the new 0B4 transaxle as used in the A5 & S5 puts the axle right at the bellhousing interface, instead of behind the bellhousing.... this makes the pulley to axle distance several inches shorter than it is with the older Audi transaxles.
Will he shouldnt need that transaxle due to the 13 inch strech infact if he uses a SBC with a 016 he should have about 6 more inches between the front of the engine and the firewall
The stock engine is right up against the firewall behind the passenger compartment. How would going longitudinal do anything except move weight away and further to the rear?

Because the engine would be in front of the rear wheel center line, instead of balanced overtop. Unless he uses the tornado transmission.
