Hey guys this is my first post just getting back into the mustang thing, bought a bolt on 89GT [gears,exhaust]. I plan on buying a topend kit from Anderson motosports for the stock block this winter, and hoping to hit 300rwhp. That should hold me over for a couple of years. But will eventually do DSS 331 or 347 stroker and would like to swap the top end over, would that get me close to 400 or would I have to do a whole new top end again. Thanks for any help?
How hard is it to make 400 rwhp on n/a 331 or 347?

build a 351 based motor for the same price as a 302 based one, make more power more safely and have more peace of mind... throw a power adder at it if you get bored with n/a and also still be confident that it will stay together

400 hp NA is very doable... but the traitor is right... going 351 based for the same price punched out to a 408-410 will make more power safer
100% off topic...
thats basicly the same cobra as that red cobra i posted the video of... but it had ac still and power steering. stock front end with GT springs... abut had a 2.2KB

Unless you're dead set on keeping it 302 base, which some people are, this is the best way to go. But if you really want 331 or 347 400+rwhp is pretty easily doable, even at a reasonable rpm range.
to add to that... when was the last time some one said i only want 400hp... then 3 months later they want 500... then 600 then 700.... you get the point...
with a stock 302 block your going to have to build ANOTHER motor at that point. with the 351 based stuff you can expand a good bit...
pretty sure as long as the heads are set up for a 1/2" head bolt they will go on... then the intake would be different. id go with one that could be set up with both a 302 and 351 with a lower swap
Chances are if your putting a top end kit from a 302 onto any bigger motor it will not make your goals.
You'd be supriesed how cheap you can build a 357w, if i was in your shoes i'd save some money and buy cyl heads, cam, and intake once

Agreed.
Take the money you were going to spend on the top end kit and go ahead and buy the 351 and get the bottom end together and ready. Or start sizing bigger stuff than you're planning and go ahead and order the top end for the bigger engine, don't put "small" stuff on a big cube engine.

I wouldnt call you a traitor if you took an 86 GT converted it to an aero, and it had a LS motor in it
But if you had a stock 5.0 with euro lights you would be a big h-mo

Haha, agreed.
Hmm, what if i Whippled this cobra motor and slammed the whole drivetrain into a gutted 4 eye notch and broke into the 9s. I wonder if I'd be a traitor then...

9's? i bet it could go 8's...
jrsblownsnake on SVTP went 8.76 (think it was a 76 he doesnt post anymore since he sold the car but it was 8's) with a 302 mod motor with a 3.4 whipple and a C4... a stock motored whippled cobra with a c4 in a light ass coupe should FLY!
Posted via Mobile Device i've got 35hp to go so come spring i'm looking into a single plane intake and custom carb. I think that should just about get me there. Price just depends on how resourceful you are. I got my long block with the cam for 1350 used. If you do your homework and catch some deals on the classifieds you can do it fairly cheap.
