Default Need advice...

I have some parts to put onto the Vette....

- Superram setup
- LPE 219 Cam
- Headers / exhaust

I plan to pick up heads and 1.6RRs, but that may not happen for a while... However, money isn't exactly abundant, and I don't have the expertise to do it myself, so someone else has to do the build.

Should I wait and do the build all at once, or put the superram and cam in, and then do the rest later? If I remember, you have to pull off the whole top end to do the heads/rrs, don't you?

Let me know what you guys think, or, if theres anything else I should look at while I'm doing this relative bolt-on build.

-Joe

In my own personal opinion... especially if you have to pay someone else for labor... I'd do it all at once. You are right that you have to tear down the entire top half to get to the heads. If you do it all at once, you're already there with the cam and header install.

Just food for thought.

Thats what I figured. Just not sure how much or how quickly I want to attack everything. I have an intake manifold gasket leak right now - I was only thinking of rushing into it because if all that had to come off to fix the gasket, might as well put the new stuff on.

It sounds like you are working with an L98. If you could swing at least intake base, heads & cam that would cover most of the common tear down areas.

Later the runners and super-ram can go on rather simply as can the headers.

Of course such changes will require some fuel delivery mods too, at least an AFPR and maybe new injectors. Then there's the issue of no EGR (I believe) when the super-ram goes in.

Hopfully someone else will chime in but I think that your 91 heads are supperior to prev years.So it may not be cost effective to purchase brand new heads

I'm pretty sure, yes... As for fuel delivery, I actually have 30lb/hr injectors for the build, as well as an afpr. The person doing the build, is doing the tune as well.
