i dont know if anyone has done a 305 swap, but the 305 and 350 are the same block, just a different crank and bore. I dont see why it wouldnt work, but then again if your gonna go 305 why not go 350 unless you just happen to have one sitting in your garage. it is possible, the bill of materials would be almost identical to that of the 350 swap

If you don't have the 305 I would not get it. I would get a 350 or a 383 Stroker(350 with 400 crank). I had a 383 in my 78 C-10 it was awesome, lots of torque. and not very expensive.

ok

thanks for the input, but my buddy had the 305 in his garage, so it would basically be free, but he just recently came across a V8 from a 80? cherokee with tranny and t-case, so i think im gonna go that route in the spring. i was just wondering about the chevy conversion because i had never heard of it, thanks again guys.

In my experience, mostly with Chevys. There is know such thing as a free engine, and ask any Camaro guy and he will tell you the best thing to use a 305 for is a boat anchor.

305s are fine engines as long as you aren't trying to build some outrageous HP hot rod. I have a 305HO in my 87 Monte Carlo SS Aerocoupe. Because it is such a good engine, I bought another one to put it in my 46 International street rod pickup. I wanted it to be dependable, get good gas mileage, and sound good. I didn't want monster HP.

Camaro guys usually want big HP. Of course, they will want a 350, but won't even settle for that. They'll have to punch the 350 out for more displacement. That wasn't really the questions. 305s are good engines and the swap isn't any harder than any other SBC swap.

I understood the question . And I personaly have a 525hp 406 in my 89 Caqmaro. What I was trying to say is if you are going with a sbc why not start wit the best platform. Parts are everywhere, you have a better choice of upgrades. and if you want to build the motor penny for penny the 350 comes out on top. sorry if you took offence but this is just my opinion and experience.

We're on the same page... I build big displacement engines for my hot rods too. I think big HP in a Jeep is a waste. Plus, if he already had a 305... Even if he didn't already have a 305, they are more easily available and cheaper than 350s as well. My point was that the 305 is far from a "boat anchor".

But no offence taken. Everyone is entitled to their opinions. I just wanted to offer an opposing view from someone who has had great success with 305s when using them for their intended purpose.

so the 305 is a good conversion, will it be too much power for the stock tranny and t-case? what type of conversion parts did u need in order to make a good swap, wires, motor mounts etc. my I-6 is starting to leak some insane amounts of oil (rear main) and i've already pulled the motor 2 times, so if i pull that ***** out again, theres gonna be a different motor put in. thanks again guys!

depending on the year of the 305 and carbwd or fuel injection you are looking at 179 hp to 200+ hp. The 2.5 is rated at 125hp not that much gain for the work involved in a swap. If you arent looking for more hp why are you considering the v-8 swap.

Torque? Maybe?

Cool factor?

50 to 75 HP is nothing to sneeze at really.

You have a good point there. I never gave the torque any thought.
