Pretty easy build, but plan on spending around $10,000.00, i've got one that will run that in a 3250 lb car. But if i had it to do over i would build an 18 degree head motor instead of a 23 degree which i have. I could have built and 18 Degree motor for the same cost as the 23 degree motor and probably had an additional 50/75 HP.
Build it right and make absolutely sure that you have the proper clearances and a good oiling system, the rest is a walk in the park. I could tell you what's in mine but we each have our own idea's of what works to achieve the same results.
