I'm looking to budget build my 340. It's out of my 71 Duster but is a 73 block. It has J heads. Looking to get close to 400 hp without having to throw a ton of many into it. Looking for help and suggestions what others built theirs like. Thanks
If I had a dollar for every thread I've read in the last 10-years where someone want lots of horsepower, but doesn't want to spend much money I would be a millionaire.
With the cost of parts today if you want a true 400 HP small block from 340" your going to spend some "Budget Breaking" money. No way around it.
