Welcome to the Michigan FBody Association website.
The Michigan FBody Association is a centralized website for FBody enthusiasts to discuss what's going on in the Michigan area. MiFbody.com was created to allow for an easy one-stop place to find out what's going on in Michigan as far as FBody events, to find out what clubs are available in your immediate area, and for an easy place to post classifieds for items you want to sell! Our goal was to create a more close-knit community of FBody enthusiasts in the state of Michigan, and to bring Camaro and Firebird enthusiasts alike together for some amazing FBody events!
The most important thing to know about the Michigan FBody Association is that we are NOT a club! The Michigan FBody Association is open to everyone, and is a community. Thus, we will have get togethers, casual cruises, events, and such like that, but this is not an exclusive club and it's 100% free to join this site! So what are you waiting for? Register now!

Building a stout 383 SBC Gen I engine, want input :)
Have you looked into the cost of getting a custom ground cam? Would probably cost you $100 more but you'd know it would be (near) perfectly spec'd for your setup. Well worth it for a stout build IMO.

not really, I've known it was an option, I just came across these cam kits which seem to have most everything needed, but it is something I will definitely consider. thanks!
I don't claim to be a pro with this stuff, but from what I was reading that cam is a pretty good fit for a healthy 383, any reason in particular you would change to a cam with less duration? just trying to learn as much as possible. thanks!
I too like less rather than more duration when possible. Won't have to rev as high, will have awesome torque and less surging which will in turn make it more fun to street drive.
also any recommendations on valve springs that are also economical in price? I've read the LS6 valve springs might be worth looking into, but again.. don't know how well they would do with a semi aggressive camshaft?
People run them in 600+ hp engines all the time, as far as I know GM runs these in all of their engines to this day. There are a couple different suppliers, some better than others but I can't remember which. I used to make them when I was at Delphi.
LS6 spring is a bit on the weaker side, low spring rate. The LS9 springs are a bit better but I'm not sure if they will fit on a SBC head with the proper installed height. I used a Lunati 74818K5 spring kit
Without firsthand experience I'd take the few negative reviews with a grain of salt, there are some sellers trying to pass off cheap lifters as GM parts.
I have to add that a good majority of the failures were due to improper pushrod length, pushrod length is crucial when it comes to genIII+ engines as they are pedestal mount unlike their older counterparts.
I would start by calling the tech support from multiple cam manufacturers. See what they recommend. And compare multiple manufacturers. That's what they are there for. And many of them are very knowledgeable.
