Ahh, those pesky Hondas...They get quite annoyed when ya wear em out with 30 year old fat block technology.
I'm building a 70 as well.
Hondas, rofl. they don't like it when a beat up old 86 Cutlass tears em apart either :). One stepped up to me on my way home tonight, the old 350 i put in that car let em have it, hehe.
I have already completed a 70 :) Anyone can see it at
www.micrsource.com/page27.html, or hometown.aol.com/micrlaser.
I have built 2 454's thus far, one cost $2500, the other cost $5000. If you want any specifics, let me know, both engines are right around 475-500 HP.
