not sure how to help u with this one.....do u just mean the ratio? if the vendor says there for lt1 engines there gonna fit. if i remember correctly i think stock ratio for lt1's are 1.5....i think u can get away with 1.7. your only gonna see maybe 10-15hp increase with this upgrade tho.

3/8" and self-aligned.

If you go with non-self-aligned rockers, you'll need screw in studs (iron heads), guideplates and hardened or chomemoly push rods.

Happy shopping

thanks i think i found some. comp cams 1.6 roller rockers. they are the steel ones that weigh as much as aluminum ones and are stronger evidently. i went with them because of what i read on another forum about power gains. i also am changing over to conical springs when i get the chance to do the project

Beehive springs are an iffy proposition. I'd stay away from them, they have a tendency to break on the top coil. And assuming you still have a stock motor otherwise, or close to stock, you dont really need much spring. An LT4 hotcam spring would likely suffice.

uhh, ok. they're still a shitty design that is susceptible to failure. Not my engine

I've been using the 26918 Comp Cams Beehive Springs for the past two years......with .594 exhaust lift.....with no issues.

The LT4 springs wouldn't have lasted 5 miles in my engine; they're (IMO) not suitable for anything other than stock application.

Hate to disagree with a Super MOD......but you're dead wrong

ok i was starting to think that i shouldn't get them. im getting head work done before i do all the stuff. i found a time i have a backup car so im taking advantage of that time to do all of my stuff at once. it looks like the first 3 days im getting body work done, then im pulling my heads and taking them to a shop to get ported and a 3 angle valve job, then im putting it all back together with a new valvetrain and cam and all the goodies.http://www.ls1.com/forums/images/smilies/dancenana.gif

Go ahead and disagree with me all you want. I think you're dead wrong

. I've seen plenty of those very COMP springs break on people. That spring design will never be a strong as a standard dual type spring, and I'm well aware of why it is designed the way it is. Besides, if his car is stock, he doesnt need anything more than a Hotcam spring. All you accomplish when you put too much spring in a motor is you eat up horsepower. Before our gear rule in my racing series, we ran our motors up to 6800-7100 rpm (circle track, so they live constantly between 4500-7000)... and guess what, I dont know of one person running a beehive type spring. I'm surprised you didnt read the endless threads that exist elsewhere on the net about people breaking them.... I hope for your sake that Comp got them figured out.
