Inliners International Forums General Discussion Hi Performance Street 292: headers vs. split manifold? Cam?

If they fit and are priced reasonable I would go for full length headers, they will add torq all the way down low too.

The short runner options would flow enough air for your engine but would lose a little low end compared to the full length headers. Of course, getting a tight seal would be key with all that exhaust air in the doghouse.

Wow that is a light van, are you sure its only 3000? My 292 63 Nova weighs almost 2900.

I've run the Offy 4bbl and big Clifford 4bbl intakes down here in Cali, never had or needed exhaust heat in the Nova. I think you could get away without it especially with the little Offy intake.

For your use, if the cam/lifters are behaving, you might just leave em as is, I would stay around 200-206 duration at .050 if you do a cam though. That 292 is so much torquier than the 230, its like you can "feel" each piston stroke as you take off from a light.
