'MORE POWER!!' 200 1985

posted by  someone claiming to be Bob Conolly on  Wed Apr 10 18:42 CST 2002 [RELATED]

Thinking of ways to improve the output of the venerable B230F.

Some things that come to mind are: porting and polishing the head (DIY?), a 3-angle valve job, cam, and exhaust. Is the VX cam as good as it is reputed to be? That flat torque curve from 2500rpm-5500rpm looks sweet.

Actually, what I'm looking for is not necessarily more power, but more usable power. It pulls strong now from above 3000 to about 4500, but the only times that I rev that high are when I'm trying to pass someone or merge onto the hiway. Around town, it's rare that I see more than 2500rpm. This car seems to be more of a highway cruiser; feels very at home between 70-85mph, and is right in the powerband at those speeds. Don't want to totally zap top end power, but since I don't normally cruise at 85...

What options exist for boring the block? Is 2500cc feasible? Has 250K on it, will probably need to be rebuilt in the near future anyway.

Thought I would ask folks who have 'been there, done that' before taking the plunge.

Thanks.
