Before I bother Paul, a bit of TLB input may be useful. It's time to do a bit more engine work on the van, but how far to go? I've got 1911 cc with quite a hot cam, ported heads and twin 40 DCNFs. This is connected to a longer ratio box so cruising at 65 is a reasonably comfortable experience. What I like: nice revive engine with plenty of power. Pulls a loaded van well, but you need to keep the revs up. What I don't like: below 3,000 revs, torque drops off fast. Below 2,000 revs there nothing - no torque and no throttle response. Reasons for the problems: The longer ratio box has big gaps between gears, so it's sometimes a struggle to bridge the gap when the torque curve is so steep. The fuelling on the DCNFs isn't great, not helping with low rev response. The cam fitted is probably a bit 'sporty' to drag such long ratios in a van. The cam is probably fairly easy to sort, but what route to take for fuelling and ignition? I'm reluctant to throw money at the DCNF set up as I'm not sure it will ever be perfect. So, new carbs or FI? 123 distributor or crank fired set up? I'm tending towards a mappable ignition so it can be set up to run better at low revs as well, but is FI going too far or will a nice new pair of carbs do the job?
