Is it hard to fit the 305 in the engine bay? (engine mounts and room)and if i do are the mounts the same for a 350 for a furture swap?

Lots of shops sell a cross member motor mount that you can bolt in if you aren't the welding sort. BUT keep in mind that if your trans is original to the 216 it woun't just bolt right up to the small block. Changing the trans means changing the drive-shaft, which, if it's a torque tube; means changing the rear axle. Common enough job, but more than just a simple engine swap. | | |

I'm putting a small block V8 in my 49 GMC 1/2 ton right now. There will be a number of things you will need to put your attention towards. Such as the guys mentioned in the previous posts. Different tranny, rear end, drive shaft? On top of that you will need to do some work on your steering box, and the fan to rad clearance. It's alot of work but when it comes together it sure is worth it.

I have a 305 and a 700r4 trans and a rear axle out of a 81 K10 that i want in. So i should use block hugger headers and just space the steering box out 2 inches? This should work for me correct? Can anyone tell me a link on a new radiator for the same truck/setup? I would like that to mount into the stock location | | | | | Joined: Jun 2011 Posts: 5,096 Crusing in the Passing Lane | | Crusing in the Passing Lane Joined: Jun 2011 Posts: 5,096 | Read the previous post about 265 manifold, not moving steering.

If you are going with a small block, 700R4, and a modern rear axle, then I will bet a dozen donuts to a dollar (old phrase adjusted for inflation) that as soon as you are done, you will say, "Dang, why didn't go with power steering while I had everything apart?" Power steering will solve the clearance problem.
I recommend strongly, ramshorn exhaust manifolds over headers.

I recommend strongly, ramshorn exhaust manifolds over headers. Do i have to use ramhorns and power steering? or can i still use my stock gear box and ramhorns for the 305? I don't have the want or need or cash to throw $500 at power steering. | | | | | Joined: Jul 2016 Posts: 32 Wrench Fetcher | | Wrench Fetcher Joined: Jul 2016 Posts: 32 | Read the previous post about 265 manifold, not moving steering.
Ed i was hoping to use a header that is better flow than stock manifold | | |
