I'm debating on a few drive train options and would like to hear what everyone else thinks. My first idea that i've been tossing around is using a triton v10 with an audi 01E. I like this engine because its different from anything else out there, reliable, and has decent power and torque. The only issue I see with this combo is weight as the engine weighs 620lbs. I've also thought about taking a 351 Windsor and stroking and boring it to a 427. I like this idea as its more authentic and fits the car better. The problem I see with this is getting a trans capable of surviving the hp and torque without breaking the bank. My third idea is to use a ford barra engine. I like this engine because they are cheap and available in my area. They also make great power with great reliability. Id like to stay away from a ford 289 or 302 as id prefer to make a more unique car. Any input is appreciated.

Don't think the Triton V10 will fit unless you are short and have no issue with the bulkhead being moved forward.
Id like to keep it ford powered
Im building a custom chassis for it so I have a bit of wiggle room. The v10 is only 3" longer than a 302.
THERE'S the answer to your quandary right there.
Come re$ale time you'll be very glad you went that way.
Seriously. Most buyers prefer traditional power trains.
And that's not even factoring in all extra time, engineering, money and hassle you'll avoid trying to shoehorn an 'off the wall' engine option into the car.

Will an 01E handle the torque of a monster motor? I think this may become an expendable item.

John, I agree. A 620 pound engine in a GT40 will not be a good choice. In light weight cars every extra unneeded pound detracts from its performance. One example from history was the Can-Am car sponsored by Dan Blocker ("Hoss Cartwright" in the TV series Bonanza). It was a conventional mid-engine layout but he used a cast iron block Chrysler Hemi. It was far too big & too heavy for that car.
My car (not a GT40) has a Donovan engine, essentially a racing aluminum small-block Chevrolet. It has a 96 lb aluminum block, aluminum heads, aluminum intake manifold, etc. and the complete engine weighs only 390 lbs. Add to that a Porsche G50 transaxle, adapter, clutch, etc. of 154lbs and a 7lb geared mini-starter and you see why my car only weighs a little over 1804lbs total.
My advice, for what its worth, is to keep it light. If you are not going to build a copy of an "original" GT40, why not choose an engine other than a Ford. The SBC has may things in its favor- it is compact, lightweight (especially with an aluminum block), powerful, and the aftermarket parts are widely available and cheap compared to other makes. The later generation Chevrolet LT- series is also becoming very popular and should be considered.

Here's some reading. The 377's are an interesting combo with middle of range rod ratios. Built to 450hp that's right at 1.2hp/ci. That's a very good number to run 92-93 octane pump gas in a 10/1- 10.75/1 CR motor.
If I was to build a new motor from scratch today I am pretty sure I would do a 331 short deck Winsor (302 stroked). Just my 2cs.

What a great playground the middleblock world has become. Just imagine being able to stuff as much as 429ci into your 351W-based block. This gives you big-inch power in a lightweight small block. How far should you go with your 351W? Displacement depends on the amount of power desired and how...

Weight's ?

Bill Mitchel 302 aluminum 4 bolt 108
This was a quick check of google sources Jegs, Summitt, ford racing, Bill Mitchel other sources may vary a pound or two. All with bored liners, main caps, and hardware.
It looks like a stock iron 351 stroked to 377 might be the way to go both $$$ and weight wise at a target of 450HP.

You've all given me quite a few things to think on, thank you.
I'M RUNNING THIS MOTOR NOW FOR 4 YEARS. I AM VERY HAPPY WITH IT. NO PROBLEMS SO FAR. GREAT HP AND TORQUE RANGE.

Albany Dave had a 408 in front of a O1E, there is some video of him racing it through the streets in the "round the houses" event in Western Australia.
Love that car, it hammered in that configuration.
Interesting thread...
The O1E would shredd its bits with a V10.
I have 5.5L twin turbo V12 going into another build, but to find a transaxle for less than £30k that can handle the 650ft/lb torque seems very daunting.
Looks like it will be Porsche transaxle for now as they are cheaper and plentiful. Hewland would be great, but tslking serious money to get it working with the engine.
In a 40, the easiest is a 347, all parts fits in. I’ve used 351C & W in mine and regretting it everytime I try to fit or buy parts for them.
Good luck

How about the Albins ST6-M or AGB? Both are under £20K from what I can tell
