If you have the same exact cars which would be cheaper to get into the mid 10s with while keeping it streetable a sn95 with 5.0 or a sn95 with a 2v mod motor?
Which would be cheaper to build?

I'd say neither also, it's kind of a ridiculous comparison because both cars would need new blocks to be reliable. at least i think...

that all depends. do you want to do that naturally aspirated or with a power adder. theres a guy with a yellow 94 gt with a 11 to 1 347 stroker with worked eddy vic jr heads, vic jr manifold and a big custom cam and a stock block that runs 10.70s in street trim on a drag radial tire. it can be done. he put 466 to the tires. the car was actually in the sept 07 issue of mm&ff. i would definitely recommend a stroked 5.0 for n/a cars. the 4.6 just doesnt have the head availability at least the 2v doesnt and not enough cubic inches to make it happen. now with a power adder that is a different story. even with nitrous i would recommend a 5.0. theres just so much more out there for a 5.0

With 11:1 compression it would not be a very fuel friendly car. You would have to buy 100 octane unleaded and that would be a little cost prohibitive for a car that is more than a weekend warrior. Might be able to get by with 97 if retarding the timing.
My point was that in a normally aspirated engine (4.6 or 347 stroker) the engine would have to be built for top end HP to get into the 10's and would not be very streetable in 25 and 35 mph zones. I am presuming he is talking about a daily driver or near daily driver.
The turbo can let you build an engine that is more streetable with power on demand. I also work with a guy that had a Cobra with a Kenne Bell supercharger on it. He showed me his dyno sheet of 597 HP and 609 lb. ft. of torque at the wheels. He put in a solid axle to take the power. This is another power on demand engine.
The other option is to add displacement. Go ahead and build a 408 Windsor or Cleveland stroker, drop in a 390, build a 400 (lots of articles to build killer 400's now and they are cheap) so that the engine doesn't need to be built to such an extreme so as to sacrifice streetability.

No i am not talking about daily driver, I am talking about weekends and nice days and going to cruises. And can go to the pump and fill up and not get 9 mile to the gallon it will have power steering and ac. It will be power adder assisted. Maybe high tens or low elevens. the base block would be a 4.6 or 5.0.. My friend already did it with a 306 and a vortech ran a 10.89.. I would def probably add some cubes.

definately probably? lol
if you throw a power adder on a well built 306 you should have no problem reaching you goal

sorry, i had to write fast i was in class and had to type fast before i got caught. haha
It would def have a power adder on it.

actually if you read through the entire thread, that 11.0 to 1 engine runs on 91 octane!!! the way he gets by with this is the aluminum heads. theres plenty of top line performance cars today running high compression on pump gas. the only accessories he doesnt have is the smog and a/c. his car is also very streetable according to what he says. with higher compression, you dont need as much timing anyways.
turbos are cool, but i think it would be cooler to have a n/a 10 second car in full street trim. his car went 10.79 in full street trim on a dot drag radial tire on 18s!!! that is sick. turbos are not as easy to work on especially with all of the extra plumbing and such. but hey its ur car and you do what you want to. just something to consider. and if you got an aftermarket block you could put the nitrous on it and go even faster. dont get me wrong, i love a good turbo car but they are really expensive to build right. i mean in right as in getting the absolute most out of it.
