A stack injection will calm a large camshaft.

I already have a 770hp/760tq GT500 and a 575hp/600tq 04 Cobra.

I am looking for a great sounding cobra that has great street manners.

I EFI for the reliability and easy starting but also want an eight stack system for looks. Yes I admit it.

Probably 425-475hp with similar torque. Some lopey idle is nice but not so much it sounds like it is going to stall every second.

My wife wants to drive it as well so I will be having power brakes and possibly power steering. Yes I know...just buy a new corvette......

I like the fact that the 427W is much lighter on the nose and handles better.

I respect others that have the true cobra period correct look and feel. I just want something that is fun.

If you have a concern about weight and handling, then a Kirkham Cobra with an all-aluminum FE weighs in around 2,100 lbs. Most other Cobra replicas weigh-in around 2,500 +/-.

Or a JBL with a small alloy Windsor or LS series engine.
Just saying.

I tried getting an answer before, but what is the weight distribution of a Kirkham like yours and have you ever put your car on a scale as Is/race weight? I've seen the weight put at anywhere "guessing" from 1900 to 2400 with an FE, but no actual numbers. I'd guess the aluminum FE would shave off around 200 pounds vs iron which puts it back in to sbf weight (not really comparable, but my fiberglass backdraft is 2434 48.5/51.5 rear bias with somewhere between 10 and 12 gallons of fuel, with about 30 pounds of misc junk in the trunk and a Windsor, so I can see the aluminum body and billet parts of the Kirkham shaving off a couple hundred pounds).

Kirkham has personally put a couple 427 cars on the scale for us on here to see, they came in at 2117 lbs with aluminum 427 FE, and 2148 lbs with an iron block Windsor with 30 gal fuel, AWESOME, HUH?

Have you put your car on the scales? (and yes, that is awesome)

Yes, my car was put on a scale. I don't have the paperwork in front of me, but IIRC, my car was 49/51 or maybe it was 51/49, i can't recall, but i'm fairly certain the total weight was 2,128 lbs. with some amount of gas in it.

Do you have an aluminum block as well?

I found the Kirkham thread where they posted weights of certain cars in various configurations, but it's tough to find any weights outside of when Kirkham weighed them so my question was just one of curiosity.

Amazing! I expect an aluminum block 427w would come in at ~2000 lbs then

Maybe, but the installation of a SB in a 427 Kirkham is extremely rare. They definitely do it in Australia with LS engines due to their regulations, but in the US, you could probably count them on one hand, not including the thumb, forefinger and pinky.

Anyone know the weight difference between an aluminum 427W and an all aluminum FE? It's gotta be less than 100lbs.
