Roller cam?
 

Does anybody know if the 87 L98 motors had roller cams? I can't find that anywhere. Thanks for the help

Yep, they did. The 305 TPI engine that was in my '87 IROC also had a roller cam.

Yes, 1986 was the cut off year and in 1987 everything went roller.

Does anybody know or have a link to where I can find the cam specs that came with those motors?

Go here:

and you'll find the info close to the bottom of the page.

So what do I have???
 

So, if I have an '87 Z28 305 TPI, I have a roller cam? Sweet... New roller rocker, roller lifters, and a better cam is looking more temptin every day....

One of the beauties of roller lifters is you can reuse them when you change the cam. Unless you know there is something wrong with one or more of them, just put them on your new cam.

Yep, not only is it roller, there's a good chance its the crappy peanut cam too. Lucky you. :) Change that baby!

Kevin91Z: Lately I've been thinking of getting SLP's 'medium' cam and crane gold roller rockers. How much power do you think I'd get out of that?

Factory cam = CRAP
They drop off around 4800 RPM in the Camaros. Keep your shift points low until you re-cam it.

Is there a table or a site where I can find out cam specs and so on based on casting #'s? I've just got an engine from a guy up the street, a 305 TPI. Not sure if it's a 86 or an 87, it's casting #'s are:

Block: 14010203, GM 5.0LG

Heads: 14014416

I've spent a good long time internet searching these #'s, and among other things wanna know if it's compatible with roller cams. I seem to get different #'s every time I do find something for that combination of casting #'s.

Checked there already, but once again a different answer. From different places I've got a definate 84, an 85, an 80-85, 82-86, 85-87 and many combinations in between. One place even mentioned it was from the late 70's!:doh: I don't seem to be getting far.

All that matters is that it's a non-roller 305.
