Hi,
Dont shoot the Noob, but I did a search and couldnt really find answers. I'm looking at several cars with Roush 427's & 402's. What are the differences between the 427R vs. the 427SR or SR w/TW (Twist Wedge Cam?). Same with the 402 series. I've looked at the numbers on the Roush site, But am more curious about the "Intangibles".
What the hell is a twist-wedge cam? When I think of a cam lobe, I think of a lobe profile that resembles the profile of an airfoil.
The 402 & 427R seem to put out the best Nums, but I'm more interested in "Streetability" & would rather have a torky engine than a high HP box.
Also just curious, but have heard "things" about the Roush Webber style FI systems- opinions?
Thanks All
