Looking for a place or person to have a swap and engine build done
Time to rent some space and go at it. F*** paying somebody, you don't learn to fish that way. It's easy.
My advice?
Start with a Magnum, add reground cam. This will put you easy 350HP/400TQ for cheap
Don't dick with cheap headers, get some doug's headers.
Focus on basic aspects of engine building, then go bigger as you get better.
And finally Get a good converter 9.5" Rebuild a 904 yourself. Don't skimp on that converter; all the information is here to do your build. Just have to execute it.
