Some of my friends have built their cobra kit cars. They're fun. Friend of mine was in the business, built many an FE engine for the cobra kit car purists, and a few cars. Craft Racing (formerly Keith Craft Racing). now out of business, unfortunately.
My friend who lives the closest, started on his in 1999. Retired in 2001 figured he had all the time in the world to finish it up. Yep sure. Finally in the finishing stages as we speak, it IS driveable but needs to come apart for finish work. Makes about 750hp, procharged BBF. it is a rocket. Scary on the streets to be honest and coming from me, that's saying something.
Fox body? They are addicted to me. I have had about 25 or 26 I lost count. They follow me around like a plague. I have ONE now, and they still find me. Current one is a 92, GT, 427" SBF, makes about 600hp. 6 speed manual. That power is utterly useless on street tires in that car, but I don't use it anyway. It was a mistake. Was supposed to be a mild 408". I don't make much money so I have to buy a part, wait til the account builds up, repeat. Well I ordered Crankshaft. Then rods. A few months later I ordered pistons. Had Craft machine the block. Bought it home in the trunk of a 93 Mustang (notchback) that I owned at the time, and started the mockup to find that the pistons were out of the cylinder some .080". That's not gonna work. What in the world? Did some digging and found that they sent me the wrong crankshaft, they sent me a 4.170" stroke and not a 4.000" stroke. I couldn't send the crank back without a huge hit in the pocketbook. The pistons would work but would require different rods. Lots of phone calls and emails and a place called "RPM" took the rods back and I got a set of custom length rods to work with what I had, and I stuffed it all together. Then hauled the rotating/reciprocating assembly down to Craft in the hatch of a '91 Mustang (5.0). Picked it up a few days later in the 93 which I still had, that 93 was originally a 4 cylinder and when I bought it I told myself it was gonna be a 4 cylinder for as long as I owned it. I got tired of 112 squirrel-power and screwed together an SVO 2.3L engine, turbocharged, 24 psi/intercooled, made about 300-ish HP. Fun car to drive. Anyway I had Ed Curtis do up the cam for the 427, with emphasis placed on driveability rather than all out power. Hydraulic roller. Ed said "you're gonna like this". Put it all together, and loaded it into the truck (03 Lightning) and headed to dyno at Craft. With a 950 carb it made 608hp at 6400 and 590 lb-ft at 5100. Surprised was not the word. It is EFI in the car now, I drive it pretty often. But it's too noisy and gets too much attention, even with a full 3" exhaust system to the bumper it's still loud. Kinda rough running but it's driveable, but frankly I'd rather drive the 4 cylinder since it's a lot smoother. And more fun. It makes maybe 50hp from idle to around 2200. Then the boost gauge starts going to the high side of zero, power starts to increase. By 2500, it goes from 3 psi to 24 psi and the "hit" of power is like getting hit in the back side, it's like the other 4 cylinders come online. The instant torque increase results in tire spin every time in first and second gear. It's done by 6000 RPM, and 6000 in 4th is 135mph.
Sold the 93 earlier this year (turbo 2.3) and ordered a 2022 ecoboost Mustang. Got it a month ago. I like it so far. Sold the 91 2 months ago. Won't sell the 92 GT until I just have to have the money. I've been offered $22k for it, though, and it was tempting. The one thing about the Ecoboost, is that you really can't tell it's turbocharged. Very little lag. That lag was kinda fun in the 93. Only time I notice it on the eco is when I smack the throttle from slow idle (standing still) and even then most people wouldn't notice it.
Dewayne's cobra (the 750hp one), he's turned down 50k for it, but I know he will get more for it once the paint and interior are all done. I just don't know if he'll drive it that much. I mean, it really is, utterly useless with that much power and only 2400 lb weight-on the street.
but yes that's my hobby and I'm thinking about picking up a 63 Falcon 2 door. Guy up the road has it and while not officially for sale, he's offered it to me for a decent (not great) price. Always liked the Falcons. Maybe I can step away from the Fox body stuff for a while.
also own a 1975 Ford Maverick, drag car only. 440" SBF, methanol, natural aspiration. Owned it over 30 years, footbrake bracket racing only. Runs 8.90's at 150+ with good air, typical 9.0's in the summer. STarted off as a father-son project in the early 1990's, and progressed from a running-on-7 cylinders 302 which I thought was sweet, to a 302 that ran on all 8, which was "way too fast" (at maybe 300hp), now is about 500lb lighter and probably makes close to 800hp on a good day. What's an 8.90 car? 0-60 in just over 1.25 second which it achieves from a standing start in roughly 55 feet. I've been a lot faster but not in that car, not mine for that matter but that's enough for now.
