[QUOTE="tt335ci03cobra, post: 12691268, member: 68944"] Just finished up that 7 part series. Nice article. I saw a fully built 5.3 stroked to 5.8 with 4 cam swaps, ported heads ditched for aftermarket heads, nitrous ditched for a 2.9 whipple ditched for twin turbos, fast efi to carb/dual carb/bbk ssi efi, as well as tons of supporting mods from rockers to oil pan/pump/fuel/spark/etc that recieved 2 different header sets make 963 on an engine dyno without full dress accessories, or full exhaust on 12.8psi. I also saw a fully undressed/non accessory/dumped exhaust "bone stock" 5.3 with an accufab throttle body and upgraded exhaust manifolds make 608hp on 11.x psi of boost with an fast system single turbo on an engine dyno... I'm not seeing 1000hp anywhere in the article and not even 610hp stock short block out of the gem you say will embarrass sc'd 4v's. I'd also venture to bet that a Chinese turbo'd budget intercooled forward facing headered street lm7 5.3 budget built as you assert without internal work will have a hard time making 450-500whp through a tranny with accessories like ac pump and an emissions compliant muffled exhaust. You're looking at $2-3,000 minimum and 30 hrs of work to put that all together on a tomato farmers budget. $300-700 for the block, $500+ for the turbo, $400 for the fmic, $1-300 in plumbing, raw materials, gaskets, clamps, fittings, etc if you go cheap or nice stuff, $2-400 forward facing headers/manifolds, etc. Let alone $400 for a hand held programmer unless you want to figure out a blow through carbbed single turbo setup, and $250-500 for dyno tuning if its efi. Oh don't forget fuel and spark mods but I won't consider that since any application, ford, Chevy, Toyota, Cadillac, et al will necessitate those so it's the same either way, probably cheaper on a cobra because the parts are more commonly bought/supply and demand. Stock 4.6L 2v mustang gt motors from 99-04 are good for/have made 450-550whp stock longblock single and twin turbo man, really not omg amazing that a stock 5.3 can do the same... Stock longblock 5.4 2v's have made 600whp on factory internals with single 66's. we all know ford 2v heads are not stock for stock, anywhere near 4v's flow wise. 125-155cfm 2v vs 225-275+cfm 4v. 03 cobras make that kind of power, 450-500whp, for $1500 on a high with bolt ons-cai, pulley, programmer, catback, o/r x. Hell for another $1500, a ported blower or used tvs can see 525-620whp... Add a $250-500 dyno tune and its a docile reliable driver. Better still, for $3.5k, you can buy a reputable single 76/68 for $800, buy your own fittings/plumbing/et al for $300, fab an exhaust out the front bumper and make 700whp on pump gas. Throw $250-500 for a tune and call it a day. Again fuel/spark mods aren't in those numbers because its the same cost on both builds. I'm obviously missing some supporting mods like maf's or +2 plugs, etc or drivetrain but you get the idea. Also, na vs na, the 324ci 5.3 made 493hp "streetable" with a 286xh cam, -5 inches of idle vacuum on an engine dyno, undressed with header only exhaust. Sean Hyland made 550hp similarly dressed/exhausted on a na 5.4 4v navigator block with 9.5/1 compression and wild 292xh cams.i don't see the super badassery even na comparing the lm7 5.3 vs the 5.4 4v navigator block. Honestly, size and packaging advantage is all I see but power wise, the 5.4 4v navigator trumps the 5.3 IMO. [/QUOTE]
