Was bored and was looking at some V6 stuff came across some roller rockers http://http://rpm-mustangs.com/cart/home.php?cat=255and how to install them http://http://rpm-mustangs.com/articles/howto-rollerrockers.html .
The site says that it gives you horses but dont say how much. Tought it was cool considering that there isnt many roller rocker threads.
Looks like a cool mod.

 

links dont worky...

 

harland sharp roller rockers give 10-12 hp over stock rockers regardless of if they are 1.8's or 1.73's

1.8's will give about .020" more lift with any cam over 1.73's (stock is 1.73 also) never buy FRPP 1.6 rockers as you will lose .024" lift with them so you won't gain anything.


harland sharp rockers are designed for 351C engines and are not exactly perfect for the 3.8. they are not centered over the valve stem. they ride on 1/2 of the top of the stem. they work but are not good for high lift cams or especially high lift reground cams. i never had a problem with mine but others have. not too many of them but some had had them slip off the top of the valve stem.


www.supersixmotorsports.com has correct geometry rockers for the 3.8. they are pricey but worth it especially if you are going to run a big cam
