What spark plugs for 1963 230 engine

[Agv63]

My 63 had a 250 , had a crank vibration, worn out journals when i got it but got worse eventually, I replaced it with a pontiac 455, as i had it with a switch pitch 400.
i love it but at times i miss the inline 6, i drove it alot more back then, and had many things to change with the 455.
With a sbc there will be less conversion but still some extra to do, a 283 works good with the trans and axle ratio, Ls will require bit more work.
I would think a 250 inline 6 would be fairly cheap and just an engine swap, no extra mods etc. Get it running and decide from there, make it drive and then see what to do and upgrades, the 6 can also make decent power with some hop up parts.

Cheers.

I would research the A/C part of the deal before making a decision. I did a vintage air sure fit kit on a small block chevy and it was pretty straight forward. I did however have to buy a beefier radiator. I'd want to know the price for a kit on a inline 6 vs a V/8 as I would hate to have any unexpected surprises down the road. For instance, what if you wanted to add power steering....easy to have AC and power steering on a V8...but a 6... well I dunno.
