One thing that was told to me time and again when I started pursuing this engine conversion was "the first two cylinders are in front of the axle on 6 cylinder cars and ruins the handling" I did think it was a bit overstated,

Ya think?
I wonder what 6 cylinder car was being referred to when they told you that or if there was just distaste for the 6 cylinder being voiced there. Unless they just ignorantly assumed that the 6 cylinder just had two extra cylinders tacked onto the front of the 4 cylinder (which would have resulted in something near a 3.3 litre!). The number one cylinder is right in line with the front axle line on a TR6. Maybe ever so slightly just off center to the rear.
Whoever told you that should definitely spend some time looking at a TR6 before they say that.
The only way the first two cylinders would be in front of the front axle would be if you attched the 6 cylinder engine via its side mount areas directly to the standard 4 cylinder mounting points. Which would shift the entire engine very much forward. You should try to replicate the TR6 mounts onto the TR4A chassis so that you can properly configure the engine.

but I thought it might be worthwhile to see how feasible it would be to move the engine back a bit more to improve the weight distribution. I do realize it will most likely mean doing some alterations to the firewall, but it might be worth it if it improves the handling.
If I were to move the front of the engine back far enough to use the TR4A mount points, would it make any real difference in handling, or am I better off investing in springs and sway bars?

If you hack at the firewall/bulkhead to move the engine further back then you will also need to attack the floorboards to move the transmission further back, then the frame to reposition the trans mount, then a different driveshaft etc...
Is there a TR6 close to you that you can look at to compare. Maybe take some measurements off of?
TR6's are a bit heavier than TR4's which can be detrimental to handling but they are not that far off. Anything you can do to lower the roll center and stiffen spring rate will improve handling at the sacrifice of ride comfort. Just tightening up the bushings, adding better springs and lowering the roll center does tremendous things for a TR6's ability to handle. As it would with most vehicles. /ubbthreads/images/graemlins/driving.gif
