well i was seaching on Speed-O-Motives site, and found this click here (setup

its to take a 305, and make it a 340 stroker. here it what it contains...
HI-NODULAR CAST 3.750" STROKER CRANK
bullet GM STAGE 1 I-BEAM RODS W/ARP WAVE LOC BOLTS
bullet KEITH BLACK HYPEREUTECTIC FLAT-TOP PISTONS-ZERO DECK COMPRESSION RATIO: 58cc 10.78-1, 64cc 10.02-1, 72cc 9.17-1, 76cc 8.8-1
bullet SEALED POWER CAST RING SET
bullet CLEVITE TRI-METAL MAIN ROD BEARINGS

i was thinking (if i would ever do this),
64CC AFR 195 heads, it would have 10.02:1 cr.
bored 30 over
a nice mild solid lifter cam (488-500ish lift)
a stall converter to match the cam (probably like a 3000), and some 410 gears, or 456's.
a RPM air-gap intake, and a 650dp holley.

i know the converter wouldnt make it to streetable, but if it were a stick car, how street able would you think it would be? and would it be worth building?

(this whole thing is just out of bordom, if your wandering).

i have a 3000 stall converter
it is pretty streetable - try to get in a civic and step on the gas, it kinda performs that way... goes up to around to mid 1000rpm on mid throttle or to 2000rpm, and starts to pick up from there

I agree on the converter, I have a Holeshot 3000 and it is very streetable. I havent had any problems or complaints yet. Depending on what kind of street driving you do the 4.10 or 4.56 might not be streetable on the highway.

Better off to get a generic SBC 350 motor. The 305 has very small bores. By the time you do all the machining, buy the parts, have it assembled and balanced, you will have more money in it and make less power.

Also, the combination of parts you have listed is a huge mismatch. A solid cam like you are indicating, along with the small bore / long stroke doesn't work.

Try something like this:
350 CI SBC w/ 9.5 - 9.7 CR.
Hyd. cam with seat duration around 270 - 275, .050 at 220. lift around .450
2600 - 2800 stall converter
1-5/8" headers into 2-1/2" exhaust
Dual plane Int w/ 600CFM carb
3.73 gears. [4.10's if you have a 28" or taller tire].

I am the guy still running a stock LG4 305 short block with about 280hp. Contrary to popoular belief a 305 will make 300hp with out much work, but any more then that and your just throwing money away. There is no way I'd bother with a stroker 305. Just doesn't make sense. If your spending that much money just grab a 350 and get the free 50 hp.

I choose not to nit-pik your choice of powerplants, but answer your question. A nice small-ish solid cam, stick or 3000 stall, and moderate gears are very streetable.

4.11 aren't very good for highway use though.

10.5:1 427, 'small' solid cam and 3.31 gearset is driven 1500 miles to/from Nashville, yearly. Pretty streetable, eh?

Gene (427L88),

So your feeling is a stroked 305 small block with a small solid cam and a 3000 converter is streetable and worth building? I will admit times have changed and so has the ideology of motor building from the overtly practicle practices that I have employed over the years.

thanks for the input guys.

i had just seen this on their site, and was wandering if it was really worth it. i dont plan on rebuild the 305, so dont worry (getting a 400 as soon as the garage goes up). i do like somthing that is reallly different tho. i know that the 305's arnt to great, because of the big stroke and small bore. i do have a stock LG4 305, that i plan on putting a small cam in it (around 400lift). just somthing to wake it up a little bit.

yes i also know that the deep gears aint good for highway useage. it wouldnt be run on the highway either.


thanks again.

aaron

wannarace,
what all did you do to your 305 to get about 280hp?


aaron

I think the 350 would be wise too. I have run a best of 14.7 @ 96 with mine and 2.73 gears and 29" tires. I think there is more tuning in there since I've only run it 4 times. I dunno if you saw my video that one of our Mikes posted but it does have pretty good power. if you find a 350 it'll be cheap, but you may end up buying a whole car to get it (that happens to me alot). I don't think you need to invest that much money into a 305 though.

GRN69, I havent a clue about a 305, but unless it can spin to 8000, I shouldn't think it would be my choice. HOWEVER, I gathered Aaron's question was more about the cam, etc, than the motor. And judging by his last reply, that was correct.

These days, I think I'd opt for a 383 setup if I was doing an sbc.

For an around town car Aaron, the gears would be fine. I find myself in 4th most often around town, and that's the equivalent of a 4.33 axle ratio.

427,

No harm, no pun intended, just a little poke to lighten up the 13th. Wanted to see if you were on your toes. [ You can always tell the lawyer in the bunch ].

PS - Goin Solid - more to come later.

I honestly believe the most overlooked motor out there, "SMALL", SB-wise, is the 307!!

3-7/8" b x 3-1/4" s!!!

A 307 will run almost as good as a 327 AND, imho, a 327 is just about right, "dead-nuts on", from the git-go!!!

He, He!! bore the sucker .060" over to make a 316" motor out of her!! AND she will run even closer to a 327.....

Only thing is, is like everybody is saying,, It's still cheaper to hop up a 350 b/c there a millions of them available AND plenty of inexpensive Overhaul kits around...

pdq67

No harm taken! So far the 13th has lived up to its rep. Evacuations, etc, etc.

my dad and i might be buying my cousins trans am witha chebby 400 in it, and we might swap the motors out, and then sell the t/a, its an 86 btw.

i know that the 350's are a dime a douzen, and thats the reason i want a 400, they are getting hard to find, great engines, and not everybody and their mom has one, no offence to those with them. and i def do know their potentials.

thanks for the replys guys. maybe one, ONE day, (after i have an extra billion $) i will build a wild 305 to see how it stacks up, but it would probably be a strip only motor.

aaron

Forget the 350 and build a 383 Stroker. If you were contemplating a 305 Stroker, go the extra mile and build the 383. You will be happy that you did it right the first time. Throw on some Vortec heads, nice big cam, either hydraulic or solid(if you want to keep chasing lash)using some of the specs the other guys have posted, and you will love it. You could always go with a 406, if you have access to a 400. I like the bigger is better philosophy.

yeah, thanks.

my main goal is to get the 400 off of my cousin and build a 406. a solid cam (or maybe a mech roller), some AFR 210 heads on it, air gap intake, 650-750 carb, and about 9:1 cr. because a few years after that is built, im going to put a ATI Procharger on it.

but for now. i just wanna get the 400 and put it in, and get some camel hump heads, and a decent cam and headers.
