Quote: Sorry for bringing up an old thread, but I've decided to put the hughes whiplash cam lifters, Rpm intake. Keep the 906 heads. MSD 6al I would like to keep the stock exhaust logs since I dont care for headers.
If I dont change to headers, will it make a huge difference?
The dyno's I have found dont test with headers, so I have no idea how much HP would be lost with the logs.
I've worked on quite a few low compression 440 and 440 exhaust manifold cars with the focus on performance.
Frankly, I'm not sure how that will work. I think your low compression motor will like the boost in cylinder pressure that this cam will give, but exhaust manifold cars usually do not respond real well to a bunch of overlap (relatively speaking).
If Hughes recommended it for your application, you should go for it, and report back.
