Tried to post questions...

And just what tires is he running?
My point exactly!

"Anymore than blah blah horsepower is too much and you won't enjoy it" lol. WTF??? I had to check the web address to be sure I'm at the right site, or is this ClubPrius.com? Don't forget the tampon dispenser on the dashboard...

So, how many Cobras have you owned, driven, or raced on a road course ?

Then again, ever have your car on a chassis dyno, you might just be surprised at what HP/tq you have at your rear wheels, even with your 460

[keezling]

I can only drive one at a time... about 425 at wheels. Surprised how?

[Mark IV]

It will be your car and by all means put whatever level of power you want in it. The point is without the right tires, 400HP will not go faster than 300.

I would suggest the Avon 205 C6ZZs as the best option for safely putting the power down.

And yes, you are paying a premium for a "sealed race engine". You can get equal or better for less money by looking around.

Chassis dyno sheet to prove your rear wheel numbers?

[keezling]

Not a big #... Road car, like the poster. Pump gas. 50k miles. No tickets or accidents. Very easy driver. Torque important for street manners. Would I suggest he won't like anything else? No...

[jordanm]

Ford doesn't post specs on the X302B, in terms of at what RPM's that power is generated. Weird?

Hell, as Patrick said you can kill yourself in these cars with 300 hp! Don't get too hung up on that number.

You know I've got that little zip tie tell-tale tag on my carb that measures how far my secondaries open. I don't think I even opened them last year at all. You can get in quite a lot of trouble just breathing off the primaries.

HA! That is the truth! I can't even find enough road around me to go WOT with secondaries wide open. Did it in the parking lot at Santa Anita Race track, which is huge, and still ran out of real estate. That's right before I was escorted off the premises by certain authorities.

You really don't need bucking, snorting, nasty manners and will probably enjoy the car a lot more with "moderate" horsepower and a reliable ride. You seem to be on the right track.

Ditto,

When I was taking the person who bought my cobra for a test drive and we were doing some hard accelerating I pointed out to him that we were just running on the primaries and that he had better be careful kicking in the secondaries. Rarely ever required the secondaries to pass someone on the highway; just a little blip of the throttle and away you go.

What Mark IV is saying is that, the usable horsepower of your engine will be directly effected by the size of your tire. If you put a rip-snorting engine with 500+ horsepower and torque in a car with skinny tires, every time you step on it you will just spin the tires. If you want a small block with big numbers, you had better consider an FIA instead of a slab side, as you can get wider rubber in the rear. If you are looking for a fun daily driver, then go with the slab side and an engine that the tires can manage. Enjoy your ride.

Very good write-up and sums it up pretty well.

I agree, well stated. The MK IIs were a wonderful balance of horsepower, torque and tire. Stray from that, and the fun just goes away. I was, thanks to a tip from Lynn Park, to fit Michelin 215/70 XWXs on the car with no rubbing anywhere.

The Ford Performance Boss 302 motor is a great streetable hydraulic roller with power right where you want it. I'll post the part # in a minute. More than enough horsepower to get in ugly trouble if you get 'stupid'. I have a manual choke Holley 600 thats trouble free, and starts easily. However, OP.. EFI is better for obvious reasons.. cold weather, alt. changes, etc..

[Armrer]

Yep, the M-6007-X302B is the unit as you mentioned. 345 hp, call them for a dyno sheet to rpm/power spread. Great engine.

The T5 is a good call. V is right on that, looking back I would have picked it over the TKO 600.

[jordanm]

So I realize this is far from an important question - but has anyone tried to put a halfway decent stereo in?

Or does wind noise wipe out that idea?

[jordanm]

And I think I am leaning back to the easy X302B and T-5 combo. Simple plain driver, and with EFI super reliable.

The Superformance 289 comes with a set of tires already I believe?

[jordanm]

Armrer - I think you guessed which shop I was talking to on this?

[RET_COP]

The stereo is good for when I'm parked overlooking the bay or quiet scenery and I want some music. When I'm driving, I like the sound of the car which usually overrides the music anyway. You should see the looks I get in a resort area when I parked eating an Ice cream listening to Led Zeppelin.

Hell, I can't hear for an hour or so after driving! Maybe someone else may have different result.
