The 305 is in a 1995 Chevy C1500.

 

I've been thinking about beefing up my 305, but, is it even worth the money? I've also thought about pulling my 305 out and maybe going with a 383 stroker. Where could I find a good deal on a 383 if I was to do an engine swap? :O

i think i would let it ride like it is for a while anless money is not a problem ! lot of changes going from a 305 to a 383 .

A 305 would make a good boat anchor. Or it would make a good coffee table if you stand it on end and put a piece of wood or glass on it. :D

This is about the only thing I would use a 305 for...

As far as changing to a 383 it will be basically bolt in, but where you are going to run into problems is the transmission, the computer, and the TBI unit. The tranny is not going to want to handle the power of the 383 without a rebuild/beef up. You will have to get a custom burned chip since your 95 is an OBD1 system, you can't just reflash it. The 305 injectors will not adequately feed the 383. The will need upgraded.

 

Can it be done? Yep.

 

Is this the type of project you want to take on? Only you can decide.

Yeah it is a project I plan on taking on, I will be getting a new tranny with it as well.

 

Where could I get a burned chip and the TBI unit would be a 4 barrel Carb instead of a 2 barrel that I have with the 305 right? :D

I did the swap pretty eaisly. just do your research and make sure all bases are covered. The biggest problem I ran into was the exhaust system. I finially found a set of headers I liked and had a local shop cusom build the rest of the system. As for the computer, call jesse bubb at www.wait4meperformance.com. he did my flash and I have never looked back. My 383 was custom built by a race motor guy and after changing the radaitor, adding fans, exhaust system and motor, I have about $15k invested. I have an additional $5k in other mods since then and I am not finished yet.

Your TBI unit will still be a "2-barrel" job. You can buy a larger ported unit from xtremefi.com and bigger injectors to feed the beast.

ACTUALLY, the 305 reacts very well to long tube headers and nitrous. We have a guy at our local drag strip that runs a 2 bolt main 305 / turbo 350 combo in a 73 Nova and it runs very consistent 12.80s on pump gas. The motor has been together three seasons and it costs him almost nothing to keep alive. Like the others, I would rather have a 350 4 bolt motor but in a pinch the 305 isn't bad. I know this isn't normal hotrod thinking but it works great for him.

X2 on the boat anchor, it is great for bogging down. :D

      This is a really late reply but I just found this thread. They won't sell the hinges. I've gone 7 rounds with them. Their solution is to buy a new cover. I'm about to buy a new cover and it won't be a Bakflip. It also won't be from realtruck.com.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Yes, and also pulling heavy trailers or a large camper up steep grades as well as descending grades such as the more rustic off road camping locations and using engine braking with that low gearing as well as soft ground can just suck the power . I realize pickups these days tend to have an over all lower first gear ratio compared to automatic transmission pickups from years back so that has helped a lot in its ability in high range but there comes a point if in four wheel drive the torque runs out at the wheels, certainly with a gas engine. They don't put two speed transfer cases on pickups for a cool factor, they have a function if one needs that massive torque to the wheels that high range can't deliver.

      Notes 7/18/2026   3,400 miles on this batch of Mobil 1 Euro 5W40 since the GDI pump replacement. Alcohol runs very clean when ring seal is tight and the sump isn't getting hosed with fuel. Checked oil level at fill up today as is my practice and grabbed a white Kleenex to look at the color. What color?  I was going to change it but.....

      Gas Prices

      By Chuck FB · Posted

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.
