I just picked up a set of Cobra 1.6 roller rockers for a VERY generous price (aka $10). I wasn't looking for them, but was buying LT's off the guy and he just wanted to get rid of them. What would be the result of putting these on my 5.0? Basically a stock engine, would it be worth it?

are those bolt down types or stud type roller rockers?

^ Was that just a dumb question?

my Cobra rockers are 1.7, if they're stock they're the bolt down type, aka pedestal mount.

Lol....thats the word i was lookin for.

My bad...meant to type 1.7. Anyway- what kinds of differences would I notice if I installed these on a stock engine? I know that the rollers reduce friction, so maybe a small hp gain? Also with the 1.7's would be a bit of an increase in redline, if I'm not mistaken. This is about all I know, if anyone can fill in more details it would be appreciated. I'm trying to decide if it would be worth it to tear everything apart and install these

it will give you a lift of about 505

yeah you will benefit from them you will reduce friction

are you running the stock cam?

cam lift with 1.6 (stock rockers) = .466

cam lift with 1.7 (cobra) rockers .473

with stock heads mabey 2hp gain, with good heads (afr 165 or equelant) they have been show to add 23hp and 12 lb-ft with a stock cam (a aftermarket cam wont be so dramatic). the area under peak see higher gains, you can gain almost 30hp at 4,000 rpm for example/
