As I am finding out it takes a heck of a lot of money to get power out of an ABF!!!!!!
Honestly, i don't know
Have a ABF friend who tuned cars since he was 15 (he is 40 now). I know his ABF have 200hp by now, he iisn't rich he just have the "know how".

Shame I cant understand it!
And very surprised he getting that power with standard inlet manifold!
Yea well i talked to him again after i posted that link and all he said "it's not that hard, if you do it yourself and
KNOW what you're doing".
He also had a pretty wicked 8v:
