how can i get 400hp out of a 318?

Some people, such as myself, are here "24/7" because of a disability and it keeps them sane. I'm sure you didn't mean that as insulting as you made it sound. I was a mechanic for almost thirty years and got hurt and now can no longer work. Although I've not built many engines lately, I assure you the ones I have built number over 100. And disassembly even more since I started as a kid in a local machine shop at the bottom rung.

True dat my friend. I havent built even 10 myself,more like 5 myself,and 3 with help when I was younger. And thats all V8's,not including the 5 yrs of small engines I built and serviced.

Here for the same reasons as stroker,allthough different circumstances in my case.

I took no offence at the know it all remark,as I know that NO-ONE can possibly know all,lol!!!

Me personally I think 400 h.p from a teen is no problem and achievable with over the counter parts.Heck even 700 h.p is do-able if your pockets are deep.

It's choosing the RIGHT parts combo that does the trick.
