I have a dart that I put a 340 in for some summer cruising, and it needs to go to the body shop for some paint work.
I currently have w2 heads on the 340, have very little experience with w anything, as I ran ported j heads last time car ran.
The question is I also have some w5 heads that are nearly ready, I did some port work, not much, mainly bowl work, removal of casting flash, maybe a little more here and there. The w2 heads have a little bowl work, chamber work, there done.
Are the w5 a significant power increase over the w2?
I actually had intended to put the w5 heads on a little bigger engine I have, close to done, 360 .070 over rare 70 date code block, perfect casting, BRC pistons, eagle rods, etc.
I should probably be patient and just run the w2 heads, and see how it runs.
But I do enjoy beating it at the drag strip, and have been wanting to get this car in the 10s on the motor.
First post, I stumbled on your forum checking out oiling improvements to the bottom end to make it survive at 7,000+ rpm.
