So why are nobody building chevy 305? are there a reason? are the crap? Are the not ment to be easy on the gas,that must be good nowadays. and the are almost for free(must be a reasone) curios??????????
no real reason , just never caught on for hot rods. they have an odd size bore. there are plenty of them in "street rods" , i know of a few....but most owners don't say they are 305s it may be due to it was never offered from the factory in a performance version , correct me if i'm wrong if i had a good one and needed a motor i'd stick it in
I can usually find a 350 for almost nothing,so why not go for more cubes,when possible? That said,both my daily drivers have 305's. They were in there when I got 'em and they still run good,just not overly powerful. Cubes are like boobs,bigger is usually better.
i have told that squire motors are the best,and a 305 is around(dont know) 3,48-3,74 bore stroke. That must be good,better than 3,48-4,00 i know newer engines are squire like 3,5- 3,5 Are there something else????????????
305 cost more to rebuild than 350s, plus there are more 350s than 305s. Also, there is no substitute for displacement. So the thinking is, why pay more to rebuild a 305, when it is cheaper and easier to find and rebuild a 350.
Hmmm im NOT in the states.there are a differense here in ol sweden. got the pic now burning 53. So there are no realy bad things whit them?
I remember reading something some where about the ports in the heads be smaller and unable to flow high volumes of air. I have one and it suits me just fine, but my car is not a hotrod.
I've had really good luck with the 305. The bad part is the heads unless you're lucky enough to have the HO 305. I've run circles around 350s with a auto trans compared to the 4 speed in mine and 4:10 rears. A good cam, headers, intake setup and ignition will wake them up. I've done the 305 only because it's the only engine I had to get the car moving and I've been happy with it and it gives me 17mpg with a tunnelram.
early? when do they come? dont say 82 cus i just got one. Thinking 350 lt1 camshaft,fixt up heads,edelbrocke intake and 4 port carb whit headers can fix up this combo for about 10 bucks for gaskets. Would it be a realible gas saver?
305 is a yucky sounding number. 327 sounds good. 302 sounds good. 307 is another yucky sounding number Might be because of my age, though!
It's just a small block chevy,they run good and will respond to speed parts like a 350 will.You will probably get more h.p. from a 350 is all. Nothing wrong with a 305,I put a Torker II intake,Quadrajet carb,HEI distributer and duals on one daily driver and it runs fairly strong,chirps the tires when it hits second gear at about 50 mph {turbo 350}. My other car has a 305 with an aftermarket cam{Summit brand},Edelbrock carb,Torker II intake, 2 1/2'' corvette exhaust manifolds with 2 1/2'' exhaust to the bumper and a Saginaw 4-speed. It will move pretty good,fries the tires taking off if you want to. Both these cars have gear ratios around 2.75:1,I imagine lower gears would be even more fun.
age has nothing to do whit it you know. Im a wery young 46 year old 25 er. and i gona tell ewerybody it´s a hot up 283. Nobody gona tell the differense,i think
Here's a great thread all about 305 building, posted by FatHack back in 2003: Chevy 305...Mighty Mouse in Underdog's costume!! http://www.jalopyjournal.com/forum/showthread.php?t=1494&showall=1 .
I like a high rpm motor myself, and my 305 didnt like high rpm. They're an alright motor. Nothing special. Hydro guys like em for the 5.0 class.
Be honest and say it's a 305,no shame in that. Plus,if you built it right and mop the floor with someone's 350,you'll feel even better about it.
actually , 305 sounds good to me.....in old Honda motorcycles this is what i think of when i hear "305"
The thing is that i had a hopt up 350 that realy put people to the place.before it blow up(no good ideea to try compress water) ewery one with a early chevy pick up know what im talking obout? so i whant a strong runing motor and a gas saver cus it´s my daily driver(52chevy pick up) And yes your right would be great to whipe them with a 305
I picked up a cheap low mileage 305 from an 80's van and put it into my 1950 Ford. it runs great, looks like any other SBC. parts for it ( intake, brackets etc. ) are cheap and easy to find. and with a 4 barrel carb and stock, cast iron exhaust manifolds it has plenty of power.
The 305 and 307 were built because of Government regulations on smog control and turned out to be low-powered,pretty descent on gas engines but by no means close to a 327,302 or a 350 as far as power .
I have a 305 in my off topic daily driver S10. It gets great gas millage, and runs like a stripped ass ape. It's stock except for a Holley intake and carb. I run a petronix in the stock distributer and it has a gear drive for noise. I tell everyone it's a 350. With a 700R4 and a 373 rear gear, it will fly down the highway. I had it fast enough to lift the wipers off the windshield. The math says I was doing 145mph, but I'm not sure if I believe that. Dean
305's had flat cams, totally shitty valve guides, and useless emissions heads. Still a few million of them rotting in boneyards for those with very limited budgets though.
Nobody's mentioning the lightened casting with wimpy main webs? A 305 block will do just fine for a stock or near-stock setup, but that's about it. Any power above that puts stresses on the block that it can't take.
I don't know about that, mine has seen 6900-7000 more than once and seemed to want more but that was enough for me
Big problem with the 305 is it got so smal bore(same stroke as 350) so you cant put big valves in it and get god flow i think its the sbc with the smalest bore if i remember right
