New member from thailand

Good day community
I’m new member from thailand. I have 70 cougar with 351 engine but i don’t know it is 351c or 351 w. I am looking for caburator,distributor and ignition system with newest technology such as electronic control etc. For good fuel consumption and avoid often tuning . Can you suggest me any brand and part no.?
And i heard about injection system for 351 engine. Is it better? Is it hard to install or modify?
Thank you very much.

I can’t help you with the parts but I wish to welcome you to the forum. Great people here and someone will chime in to help. You have a beautiful country as I have worked in Chon Buri and Pattaya many times. By the way, we need pictures.
