347 with a blower pushing 22 lbs will do the job. Going to add small 35 shot no2 and some more tuning so that I can take care of those modded ZO6's. Kinda hard to talk when you cant keep up with them, so it will be time come this spring!

I think Im going to just eventually go with a NA aluminum headed 347.

a strong all motor car is not that much fun if you drive it on a daily basis.

Slap at least 10psi of boost on the car with heads/cam and you will be more than happy.

I agree, the car wont be as much fun as a car with boost but thats okay. Im just looking for about 350-370 rwhp and something that I can take out daily.

just as long as you realize drivability will not be as good in a n/a car as it is in a boosted car

The 347 I build I would probably go with hopefully wont be too nasty. Basic aluminum heads/intake/ed curtis cam...I really want it to be streetable and daily drivable. If not maybe a S-trim or something.

Just look at racerbox77 car 10 psi vortech and exhaust. thats all you will need. Wifes red one with a vortech smacks them around and the teal one destroys them. both the cobras still have all the factory internals. And this is a 03 cobra with every single bolt on you can buy except for a KB or whimple that i raced.

yep that's right I drove around with Heads and Cam for almost 2years with no tune. The drivability was not the best. This past summer I added a S-trim and it drives like it is almost stock. But with 200 more HP. I would add a blower before I would stroke a 5.0, but that is just my opinion:banana:

Fwiw...

Gt-40 gear, full exhaust, e-cam and 12lbs from an strim will get you 450rwhp on a safe good tune and put you in the low 11's all day. you are at the limit of the block there...but it will get you the numbers...

I had an a-trim with the original gt-40 (L-casting) iron heads years ago pushing 9 lbs and got 440 rwhp...went 12'0s on street tires spinning pretty much thru 1st and 2nd...

The fox has such a weight advantage that it does not take as much to run the numbers...

True story. I love the fox because it uses the KISS method.:rockon:

I went mid 10's on a mostly stock 93 cobra engine for a couple years without issue. It's hard to beat the simplicity of a cobra 5.0 when making power under boost.

However, my 03 is a beast as well with simple mods. Either way, they're both cheap to make fast.

It's not as bad as you'd think. My '03 has 13k on it, now price a pristine 93 cobra with 13k. We're only talking about 5G's difference roughly.

why would you buy a 93 with 13k on it only to mod the shit out of it?? buy something with closer to 100k. save 10 grand and go to town with it.
