So basically I have to order your cam first to get a cam card and then talk to Comp Cams for springs and such? If so that fine whatever but just trying to get all parts together here so I can get this back together when it gets outta the shop.
You'll want to talk to Comp cams for the best solution for your vehicle: 8.1L Springs - Comp Cams
911-16 Springs are most likely stock replacements as there are no lift figures on the page for them.
26120-16 Beehive springs are rated to .590 lift.
Your installation of the 205 camshaft (.600+ lift) on highly modified iron heads with aftermarket pistons will be a custom installation which will require the new springs that have the correct ID / OD measurements. You or your machine shop will want to talk to Comp cams directly to spec the right parts for your vehicle.
The 203 camshaft (.530 lift) should be fine with Beehive springs, but again, call Comp for more information on their parts.
Well F*&K me in the A$$. Was almost done with rough cutting and broke thru the runner on my intake. Its small and not in a bad spot so do you think a welder would be able to tig it up? Lord I hope so. If not anyone see any problems with epoxy? Its a n/a engine so not like its seeing a huge psi plenum.
Still have to do the final touches but heres where it is as of now. Theres alot more meat than I thought on right side. Not so much on left where it looks to be more than it is.
You can weld it up, or you can leave it and it won't make any difference whatsoever. I blew through the same spot on our original prototype modified intake manifold which we were just using for engine dyno testing. We tossed it on, watched fuel trims / cylinder exhaust temps / etc. and saw no issues with it, so we've run it daily (for the last 50,000 miles) on our black shop suburban with the 540cid stroker engine / 213 cam / aluminum heads.
For the race purists, I'm sure that cylinder sees a slightly different flow rate than the other seven, but we ran it on ported stock cylinder heads and then aluminum cylinder heads. When we removed the heads for the swap, we saw no obvious visual issues with the pistons after 25,000 miles of use. Its done another 25,000 since then - the engine hasn't had any issues whatsoever.
I should note that my prototype intake manifold is the only Raylar modded intake manifold with a hole in its runner. All manifolds after our initial prototype manifold are inspected to make sure there are no defects in the final product.

Lol ^^^^. I doubt anyone thinks you would put out a holy intake
STILL waiting on machine shop to get to my block. Dude has been out in Cali working with Rahal Racing and just got back so hopefully soon.
Anyways Im still on track with this. Should know here soon and will be ordering the pistons based off what the bores are like but to me they miced fine. Then the cam once I get a hold of Comp and talk to machinist about those. Still thinking the 205 for now so I wont be going back into it when I get heads next year. Hell at this point it might be next year anyways.
My truck is around 430-450hp at the crank with a bp202, duel magnaflow muffler, stainless works headers, cold air intake, and a tune. Dynoed at 333/432 wheels.
The hot rod 203 camshaft will give you a bit more chop and still works with stock pistons. Here's a video of an avalanche (with glasspacks?) running the 203.
You can get lots more chop with great driveability from our biggest cams - 206 and 213, but they have too much lift for stock pistons (.600+) so you'll have to swap to a set of our notched pistons to run them.
