305 sbc...
A 305 Chevy has enough potential to make for a pretty nasty street engine. You need to have a pretty decent knowledge of automotive engines to realize that. You obviously don't. It's not the best, baddest, most efficient, whatever, but it's certainly not a boat anchor. Ignorance is ignoring.

Man, go build your 305 and waste money on it. Sure you want to be different just like the other guys who dumped money in their 305s and now regret it. Take some advice from guys that have actually owned them and do a 350 or bigger. I gave my 305 away for free because I knew that it wasn't worth much.
do a search on thirdgen.org for Willie. he's running a splayed capped 305 tpi with twins...and i believe his pistons are JE's..."APBA" i believe is the line, as in American Power Boat Association, where they have classes that limit you to a 305, with blowers and such 
and i built a 423hp 305 n/a a few years back, and it went faster than every one of Zones builds to date if i remember correctly

an engine builder once told me it doesnt matter the cubic inch of the motor if its boosted.
give him a day with 2 different cubic inch motors, and he will have the lesser motor making the same power as the larger motor.
case in point, tommy brewer ran limited street in his SVO with only a 363 inch motor and an f3, and was spanking guys running 4-500 inch boosted motors.
thanks for the link to this thread, btw. its quite entertaining.

Just about everyone makes pistons for a stock stroke 305, but no one makes a stroker piston. I can understand, as it is probably not common, but I don't think it'd be too much to get some done.
Keith Black has a 2618 alloy forged piston made for them that is for a 3.75" stroke crank and has a 10cc dish to it. If you are useing 5.7" rods the part # is KB834 and if you have a 6" rod it is KB835. Then all you need is your bore size that you want to finish the part # off http://kb-silvolite.com/forged.php?a...tails&P_id=440 . They should have them on the shelf and ready to ship for you. I use this stroker combo in a certain circle track class where I'm very limited for total cubic inches, and yes it does make more HP & TQ than the other 350's in this same class!! But hell bigger is always better, right.........
EDIT: I gave this info out in another thread that we bolth replied to.

Actually, they make a 335 stroker piston. Didnt i tell you 400 HP is not impossible, especially at 1.5 HP per cube? I was speaking NA.
My 1000$ 383 made about 500 HP with 9.6 to 1 compression, so i doubt that.
Goes both ways there buddy, i we both have valid statements, but you are not listening to what i am saying. I simply told you ONCE AGAIN that HP per dollar, it is not efficient. And efficiency is important, you must be a honda owner...or a ricer rather. I understand taking something you have and running with it, but the cubes are just there for a 350, not to mention the aftermarket support. More air and fuel being burnt means more power.
Come on, tell me the 305 can make as much as a 400 SBC? Or a bigger motor, i am still waiting.
Now are we talking Power to weight ratio? Lets stick with the same weight car and drive line.

10 Camaros You Should Never Buy
Well I gave you a manufacture on the first page to look at. Keith Black has a 2618 alloy forged piston made for them that is for a 3.75" stroke crank and has a 10cc dish to it. If you are useing 5.7" rods the part # is KB834 and if you have a 6" rod it is KB835.

How much do they usually run? Around $500-600 or so?

You have this narrow minded thought process that tells you small bore = bad! You probably still think you can see a engine's A/F ratio with EGT's! That was a common misconception rampant 20-30 years ago, and it still is today, even though there are tremendous volumes of information out there to prove otherwise. Remeber what I said, "reason may mislead us."
IT CAN! Look at the 360ci NMRA Hot Street motors. They're making well over 800hp on the engine dyno. That's close to double that of what your average 400+ci motors make, and even more than a lot of 470-500ci Big Blocks. I said this before, and I'll say it again...it all depends.

i just took the link over here from thirdgen.org. this is pretty amusing...i think it's impractical to try to wring all this power out of a 305, but i don't think it's impossible...take it for what its worth, but look over at club rsx--it's not uncommon to see a 700+ hp k series, but they're boosted to kingdom come- and yes, most claim to run pump gas.

NHRA Super Stock! I personally know a guy, Larry Hodge, who runs a Monte Carlo 310ci, 416 casting heads 1.84/1.50 manley valves, +.700" lift solid roller, flattop pistons, 7800RPM shifts, 8700 across the stripe...6.50s at 105mph or something like that at out local 1/8 track. Idk about the 1/4 but he said when all said and done that it should go 10.30's or so.
Heads must maintain stock valve sizes and runner VOLUMES...BUT the use of epoxy is allowed. The runner is FULLY PORTED at the stock 163cc volume!
538hp!!!!....575+hp could be had ALL DAY at 13:1 with a REAL head on it!
BUTTTTT....a 383ci would make 675HP!!!! a 406ci would make 700...

horsepower to weight ratio..... reminds me of johnny ricer. funny stuff!
im pissed at myself cause i posted in this thread.
thanks for the link.
I think this would be interesting as a 305 will run forever as long as you take care of them. My old thirdgen had 211,000 on it and still ran strong. Now when it comes to boost doesn't a 305 use the same crank and rods as a 350? Same stroke correct? Most stock 305's also run around 8.5:1 compression too correct? Boost friendly compression stock for the most part. I've never seen a bad *** 305 but I'd be open to the possibility however if it was me I'd just build a 350. My 305 in my truck won't pull a dead ***** out of bed and it's mildly built. They just don't make the torque the larger cubed motors make. Anyway.......... continue conversation...........

I remember a while back Hotrod magazine did a dyno shootout between two motors of about the same size, one was a large bore short stroke motor the other was a long stroke small bore. Both motors made almost identical horse power and torque numbers. I'll dig around and see if I can find that article.
Also check out Hotrod's pump gas drags or their Dragweek and see the motors those guys are running. Some of the smaller motors are out running the bigger ones, it all has to do with your combo and making sure it all works together.
Build that 305 and shut some of these people up.
