Is this cam too small for my build? I'm in the middle of having a 383 stroker built at a good shop in town. The builder suggested a cam to me the other day, and it seems a bit small (but I'm VERY VERY new to all this), so I thought I'd post the numbers up and ask about it. It's an Isky cam.
Intake/Exhaust @ 50 = 234/246. LC 110
Thanks for any input,
Amanda

A lot depends on how you plan to use the engine. For a DD that's plenty of cam. Much more than that and you'll probably enter into low vacuum issues, raunchy idle (which you may or may not want), need for gears and converter, moving the power band UP, etc.
Since cams are often measured in 6 degree increments (to go from on size to the next) your next step up would be 240/252 @ .050".
Be reminded, far too many over cam their engines. The thinking being "bigger is better", which often isn't the case.

The car currently has 4.10 gears and I have a 3600 stall sitting on the shelf waiting to go in when we put the engine back in. The car does get driven on the street, but it's at the track every weekend as well, and I'm looking to pull as much outta this motor as I can.
I dont know the lobes or the application that your building for other than a 383ci. Maybe you can elaborate on the setup?
If you just are basing this merely off size than a 234/246 on a 110lsa is big enough for a stock PCM car.
Spec'ing a cam shouldnt just be about big numbers either, they should be done for setups. Bigger is not always better. I have a 242/248 on 115lsa in my 398ci.
