Need cam advice for this setup
Check the engine specs in my sig. I'm thinking about stroking the bottom end of this engine and I'm curious what cam would best suit this setup with a change up to 383ci. What if I swapped in AFR 190's to boot? Any other nit-pick mods I need to be aware of with the increased cubic inches? How high a compression ratio should I run with this setup and still use pump gas?

Re: Need cam advice for this setup (ANTI VENOM)
A proven set up with a super ram 383ci motor is the LPE219 cam. Many here on the forum(Beach,JD, etc) run this set up with times in the mid 11's! I would keep the compression ratio below 11.5:1. Its possible to run higher on pump gas, but not you'll need a bigger cam to bleed off cylinder pressure and really good tuning.
The comp cams extreem grinds are agressive lobes that build cylinder pressure early, which is similiar to the LPE grind. :yesnod:

Basd on your sig, I am guessing your car is a '91 (ZZ3 motor). If that is the case, you probably want to stick to 10.5 or less compression if you build it up.

10.5 is as high as I would go on a L98. Many have had great result with the LPE 219 cams. If you want something more radical I would go with a custom comp cams grind.
