Cam & mods
O.K., I have narrowed the selection to LPE 74219 or
Comp Cams ( 224/230@.050).
I will have heads ported but I'll stay with stock valves.
The question is: can I use stock valve springs?

Re: Cam & mods (pwrful c4)
You will need stiffer valve springs.Usually you can get them with the cam. :steering:
It is always a good idea to get new springs when you do a cam anyway if you have lots of miles on the old ones.. nice insurance..

Re: Cam & mods (Sliding)
You need valve springs that are suited to those cams, give Lingenfelter and CC a call and see what they recommend.

Re: Cam & mods (vader86)
comp cams just developed a new egg shaped (ls1 style) spring that fits in the stock spring pockets and if i remember correctly everything was near spec for the 74219 cam...which I reccomend. Are you ever going to change intakes?

"I wonder why they would do that? They already sell springs that fit the LT1's with no mods."
If you look at Slidings profile it shows he owns a 90 L98. These use 1.24" valvesprings, that are smaller in diameter than the LT1's 1.30" valvesprings.

Re: Cam & mods (Davemc1963-87conv)
My heads guy says any performance cam will need stiffer springs, which
still won't last that long (30k mi, or 50k mi if you don't get on it that much)
anyway. With your new cam, you will have to change springs periodically.
