Gentleman (and Ladies): I'm wrapping up my frame/ body repairs on my '74 and turning my attention to my stock 1.8L carburated power plant.
With so many variables to consider, I thought I'd throw it out to you for your thoughts on a good combination. (IMG:style_emoticons/default/stirthepot.gif) Starting with a stock 1.8L, the goal is build an engine with a balance of power and efficiency for a daily driver with a kick. What I have found so far, for consideration is: 1. Increase displacement with a longer stroke: 71mm to 78mm (and corresponding rods) 2. Larger P/C's from 90.5mm to 94mm (or 96mm) 3. Mild cam (Webcam 86a or 494) 4. Switch to dual carbs vs. the current single. This combo would provide an increase from 1.827L to 2.165L The questions that come up are: 1. Will this combo meet the goal? 2. Are 1.8L heads okay on this engine or do I need to find 2.0L heads? (the 86a cam would require better valve springs I gather) 3. Should I lighten up the flywheel? One other biggie, since I'm in the Northeast: Where can I have machine work done? Loads of places in CA, do I need to ship my heads and possibly the case out to CA or is there someone closer? There's a lot of wisdom and experience out there, any help would be greatly appreciated and might save me a couple bucks! Thanks! ScottD (IMG:style_emoticons/default/aktion035.gif) |
