Rebuild 302HO or Go crate turnkey?

Okay guys heads up! Can you plz help make up my mind? My 5.0HO motor is stock with mild mods. I sport only a BBK coldair intake,Deleted EGR stuff including smog pump,EGR blockoff plate,Pacesetter longtubes,catless X-pipe & flowmaster catbacks.This motor has over 93,000 original miles on it with the AODE tranny.The question here is should I rebuild this from bottom up or just the top half? Would it just be cheaper in the long run to go crate turnkey? This will be a street/strip rod.My rearend is still stock also w/3.27 trac-lok lsd. Should I stay w/this or go 3.73+new lsd? I'd love to make 380-450RWHP!Anywhere in that median.

If rebuilding motor go forged and throw a blower or turbos in the mix and if going track rebuild the rear end.

Mahalo brah! I'll keep that in mind. So I should skid the stock internals then? ie:crank,conrods,pistons etc.
As far as the stock cyl.heads is there a way to do away with
the emission tubes coming from heads for the EGR recycler?

Really? See this is only my second streetrod to date.My first
was a 1989 Camaro IROC-Z 5.7L TPI which was blk/gld with
a 5spd. stick tranny and a Hurst shifter,The previous owner
used to race it Prostreet in Honolulu,Oahu and for state titles.Man,was this a HS graduation gift too remember.But
like an uneducated fool of hotrods I sold it! Was only 18 then, Now I'm 37 and it's time for
redemption! YES! In a Ford.A Ford what? A Ford Mustang GT!
Though I wish it was a COBRA w/a stick trans.! For free can't complain.Btw,hey stmpede educate me, What makes you say it isn't broken in yet? I'm curious.

I agree there, maybe just a re-ring build... skip the forged stuff unless you plan on spraying alot of giggly or boost, or actually making over 500 crank

you'll spend alot of money and make the bottom heavy.

There are countless stories of 5.0 motors running way past the century mark with big power adders and no issues.

Don't waste your money rebuilding the stock E7 heads, you can get a nice set of ported E7's from PowerHeads or the Flotek's from Tri City for almost the same price a machine shop will charge to rebuild the stockers. As far as the bottom end be realalistic, if your more street than race just rebuild what you got. Stock bottom ends are good for 400hp but you might want to add a windage tray/ girdle just to be safe

Hey mahalo SSB! You make a whole lot of sense dude.Not a very costly idea.Yeah I don't plan to put NOS or any type of boost.Just bolt on stuff like bigger heads and intake manifolds,Prolly Vic juniors or Trickflow's. Bigger TB a accufab or brothers 70mm connected to 75 or 80mm MAF also by accufab.Then for guns prolly 24lb.summits,Oh yeah we can't forget about the camshaft now can we? NO! I'll go with a B303FRPP or one from Compcams (pn#35-351-18)per summitracing.Specs are duration@270/276 & lift is @ .512/.512Hydro-roller and to keep it all cool an electric waterpump w/UD pullies.

Re: Rebuild 302HO or Go crate turnkey?

i got a set of 165 AFR's for sale and a Holley intake, we just took off of a 302. With a stock cam it ran 12.7's on DR's on a motor with over 100k on it. We had the heads on there for about a 1000 miles. He has been bit really bad and we are building a 351 for it now. So i pulled the motor to sell the parts off to finance his new build. Let me know if you are interested.

well you wont run Jr.s with a cam, you will hit the piston. You need a 1.94 valve with under 500 lift to keep it safe.

i make 456 at the wheels wit all stock stuff. i run srp pistons but its nothn to write home about. siverstangboy says 500 at the crank, i say 500 at the wheels. and wit 93k on the block...i'd only freshen up/upgrade valvesprings for the new cam. if you decide to kkep the e7's. and save up your money for a blower or turbo. definatley just do a stock rebuild, if that's wut u wanna do.
