ideas for a stroker

Hi,I have a 1989 Camaro RS with a 305 TBI and a five speed. I recently pulled the motor and trans, planning on doing an overhaul, but I was wondering what kind of performance stuff is out there for that motor? I found a stroker kit that will add like 30 cubic inches. I'm not sure on what kind of heads I should use. I mean is 64cc's okay? Or no? Really what I'm shooting for is 400 hp, or as close as I can get. Any advice would be greatly appreciated.  

Build a 350 400hp will be easy.  

400 horsepower is a bit of a lofty goal for a 305 actually, a stroker crank may help some, but it will help very little...

Everyone is going to bash the 305 and say get a 350, that's just how it is.  

Best thing is to look at your budget, and figure out what you can afford without breaking yourself. If you've got the money to build a 350 for your Camaro, build a 350. If you don't, then the stroker kit for the 305 is a decent option. It probably won't make 400 HP, but it'll make a ton of torque that'll make your Camaro really fun to drive, though I'd defintiely recommend subframe connectors from someone like BMR to stiffen the chassis.

When figuring your budget, don't forget to set aside money for a trans rebuild.  

I'm not bashing the 305, but it would be cheaper and more effective to get a used vortec 350, go through it, replace the cam and valve springs with a mild cam.440 lift or less, put a performer intake and a 600 cfm carb, than it would be to get a stroker crank have all the machine work done, and adapt the TBI to supply 400hp.

Read through some of this.  http://www.thirdgen.org/techboard/engine-swap/382827-has-anyone-board-built.html  

Here we go again. Reading all these post has left me flabbergasted as it reminded me of another person wanting to build a 305 on this site.  While can understand the whole 350 engine arguement I can't understand why more time couldn't have been spent trying to help the person posting the original question.  There should be enough supposed talent on this site to have provided numerous suggestions on how he could accomplish his goal.  Instead it appears most of the posts were spent telling him he's an idiot for wanting to achieve his goal of building a 305 to meet his needs.  You, we, are supposed to be car enthusiasts not bashers.  As such I would expect some disagreement but I would expect more support.  I belive it's one thing to say 'hey, if I had to do this I would use a 350 instead.  But if your set on using the 305 start with .........' and a whole other to say your an idiot for not useing a 350.  Many build ups start the same way, use what you have and start with the basicis and work toward the more costly or time intensive.  Improve your exhaust.  Improve your intake.  Improve your cam.  Improve your heads.  Stroke it.  Anyway, I'd like to see a comparison on a 300 hp 350 and a stroked 300 hp 305 (335).  Since the 305 was a 'torque' motor and would move most anything chevy built and did it with few cubic inches to feed there must be potential.  The arguments I've read here remind me of the old arguements about using the chevy 400 because it was a p.o.s. but now they are 'mainstream'and getting harder to find.  How about the rice burners with their 4 cyl that will get 20+ mpg and run the 1/4 mile in respectable times.  The 305 does have potential if only people are willing to find it vs writing it off because of their biases.  

Based on what I've read elsewhere the vortec heads seem to work the best.  There are some good replacement manifolds for TBI but they can be expensive.  People I know use the performer series manifolds and use a TBI adaptor to get it hooked up and used manifolds are reasonable on craigslist or swap meets. There are several camshafts that will work well with the stock TBI and provide improvement over stock.  However I don't know if the stock ecu will support 400hp with out some reprograming.  The 305 is more of a torque motor so you may not need 400hp to get what you want and stroking the motor will definatly add torque and that seat of the pants, plant you in your seat feeling. Somewhere online there was a build up of a non-stroked 305 that hit the low 300's for hp with heads, cam, intake and exhaust.  I would just guess that adding a stroker kit to that build would increase the hp somewhat but would jump the torque even more.  Good luck and if you get it built, please post your findings/satisfaction with your build up.  

because the person will spend the same amount of money to build a 335 as it would cost to build a 383.they want a streetable 400hp that is tough with 335 not at all with a 383 plus the low end torque(which is what you really feel on the street) is way better from a 383.there is simply no replacement for displacement,if i could get a 502 for the same price as a 383 i would have one.btw rice burners dont run respectable e.t.'s at all unless they are running boost or on the bottle,and even then they are not very fast thats why you never see them do *** against real muscle on pinks all out same as you dont see 305's or 335's onthere either but you do see 383's at the track.its not some conspiracy and the 305 is really badass its simply that they cost the same to build as a 350/383 and you would just be dissapointed when someone with a 383 dusted you and your 335.  

id you do go with a 305 , you may want to supercharge or turbo to see the numbers u want.

also eq made some good cylinder heads for the 305.

i would not want to race a 5.0 mustang with a 305.  

nope or a old DZ302 camaro those are some potent little motors but not a 305  

305's in my opinion are ok. I had a 86z28 with a tbi 305 with mild upgrades and it wasn't to bad. Felt fast but i got roasted by a early 90's v-6 mustang in the 1/8th. EMBARRASING. Also have a 383 stroker will help sell  your car better. People want 383's more than 305's.
400 hp is achievable however. Some good heads with a midrange cam. Stroke it and use longer rods. Use forged lightweight pistons and try for a 10.1 compression. Depending on piston size, 64cc heads with 2.02/1.6 valves, approx. 180cc runners would be good heads for a 10.1 cr. Also upgrade your ignition and cooling system.  

Ideas for the 305  stroker crank,lite weight pistons,set piston to deck height @.005,use the H.O. heads[they use 1.840 int valve& 1.500 exh valve] gasket match and pocket port both int & exh,balance engine,Lunati cam 219/227 .468/.489,Performer RPM,Holley 650, good headers & exhaust to fit the ride.Thats what I would do if I wanted to spend the money.  

Hi there,
   I have posted a few views about the 305 I threw a lot of money at for 246 hp.
   Then there was a post about a 305 owner who used much larger cam etc than
   myself along with after market special heads and I think that he made 340HP?
    That would have been a real bone shaker I believe.
   I have already discussed the idea of stroking the motor and that does not
   warrant the expense $ for $.. Either way without boost or Dentist gas you
   simply wont make a streetable 400Hp or anything like it.
   I strongly suggest that you sonic test the poorly cast cylinder walls of these
   blocks which are hard pressed to make more than 60/1000" overbore and even
  then
   they are NOT a good proposition..For Class racers the factory did list a few
   years ago a new casting which would not agree with economics of an average
   project. Also TFS make special heads for these motors but in terms of real ***
   you would be better off with another choice..Even a 307 is more user friendly
   and 300hp is a logical and streetable aim with 1.94" inlets  in 170 heads &
   9/1 compression.There are many other choices than this 305". It's all up to
   you!! [Cool Hand Luke.] All the very best with the project and remember that

   when in doubt,..DON'T....Skyeking....

Agreed skyeking, you can build more power for the same money.
