305 to 350 swap

[Jesse Smith]

Well I planned on going 305 to 305, but that fell through, so now we’re going to a 350. Old and new engines are both carbed. Will the old transmission work? Should everything line up correctly? Is there anything else i should be aware of going into this stage of the project? Thanks guys

Yes. No.

If you have teh factory exhaust manifolds, the passenger side has a different bolt arrangement on the rear bolt of the # 8 cylinder. seems like there was some other minor bs too, but it's been about 15 years since I did that swap. I remember there being just enough differences to get me swearing. Probably not a big deal if you have a bit of budget for it, but at the time I didn't. went into it with the mindset that it would be 100% direct swap. It's maybe a 95% direct swap in reality.

The year range of the two engines can cause a little bit of trouble if they don't jive.
