yeah for real. they kept saying the site that they got the parts from, im sure that was it though. the conversion kit was kinda expensive if i remember right. think it was like 4-5k.

Old Shelby, Jeff? You mean the 427 Cobra that killed so many of it's owners in the first 6 months of production that they stopped making it? :P It won't be that fast to me; I didn't buy speed I earned speed, and I'm used to something that pulls like that and can respect it.
Low mileage L33 are going for $800-900 locally, and are light enough they won't hurt the Miata's handling. Make a wiring harness out of ---- laying around, run another $400 used AEM, while involved it'll be easier than NA to TT wiring on an Mk4 Supra. Fitting the engine doesn't impress me it's just position and measure work, nothing like having to redo suspension or dangle a FWD drivetrain. Dunno what trans I'll run yet, $150+ for the clutch, and $150 to cut the driveshaft. Depending on what I give for the Miata, $2200-3200 out the door.
I kinda feel bad about no turbo involved but one won't be needed.

1.8 rear end will hold 500. The trick is not to run the junk suspension that does nothing to prevent wheelhop.
There's a 175 lb weight range among LSx flavors. Which were you thinking of that's so much heavier than the cast iron Miata mill? You know LS1 weigh 325, and L33 less.

I don't the exact weights of all the v8's. I know they add weight, but it's not crazy. Most add 150-250 pounds to the car doing a lsx swap. Depends what you do. Some have done the swap and kept the weight and distribution the same. I know what a L33 is. To me, it's not worth it. If you're gonna do all this, do it right. I'll take 50 pounds for an extra 50 ft*lbs.

An all iron block, all iron head 5.0 adds 250 lbs. An L33 weighs a lot less, add a plastic intake manifold.
I think it's funny to argue horsepower ratings of drivetrain with you, since nothing in the drivetrain cares about horsepower. I've yet to see more than four IRS imports whose rear ends were correctly damped to prevent hop/chatter under power. The last turbo Miata I tuned did it at 200 whp, I could feel it but the owner couldn't, yes it destroyed the rear end and yes he finished top five out of whole fields of cars at autocross events - how does someone like that not notice? Hrm, it just takes a cage (or hardtop) and arm restraints to take a Miata to the strip, but I've only seem two in a decade. I posit the entirety of online Miata tech knowledge is lacking in fundimental ways because of this lack - like it or not, you want to talk power you talk to a drag racer not a guy who goes in for twisties.
