magnum 318 build
 

92 dakota, 5.2 with 138000. Taking the engine out in 3 weeks to go through it. I would like to have 450-500 hp by the start of the season next year and keep it injected if possible. Any ideas would be much appreciated....

You ll prolly be cheaper off to order a crate stroker engine to make around 400 ponies. Than to build but that's my thought if u still wanna do the build yourself. Look at what crate engines have for parts if a good starting point and go from there
