If you built it right very reliable, and worth it? if you had the right set up you could probably get 350whp, Is that worth it to you? for what you'd have to do i'd build a different series B or K if that swap could be put into your budget. by forging all the internals and sleeving the block in a B or K series you could make alot more....Do some reasearch online, look at some different setups, decide which is best for you, form a plan, and then ask some questions.....
