Anyone ever heard of/dealt with Solid Tech Performance? I think they've got the best overall deal on a monster level 2 clutch for me, but I can't get a hold of them.
Never heard of them. Did you call Colorado speed? They seem to give some of the best prices out there if you call them. They can't advertise below MSRP. EDIT: Forgot cuz Canada
I ordered a dial indicator and magnetic stand as well as a deck bridge stand so I can start on the 383.
There are a lot of unknowns with this engine since the guy wasn't given a build sheet. Here is a list of things I need to do before I order parts:
Measure piston to deck height
Measure piston valve relief volume
CC Cylinder head combustion chambers
Measure free valve drop
PTV clearance shouldn't be an issue since it has pretty big valve reliefs. I want to get the static compression up as high as I can since I'm guessing the reliefs are 6cc. That's about twice as big as I'd like. All of those measurements work together to help me determine optimal head gasket thickness to reach my desired quench distance and static compression ratio, or get as close to it as I can.
I'd like to see 11.5:1 SCR and .035" quench. I'll probably have to order a custom thickness gasket from Cometic to do that. If the piston deck height happens to be 0 I can probably use an off the shelf .040" Cometic.
After I figure out what gaskets I need and get them in I can mock it up and start measuring for pushrod length. Between now and then I am going to consult Tony Mamo (formerly of AFR) about lifters for this build. I am going to use a premium lifter. I've seen too many failures of stock LS7 lifters and cheaper aftermarket lifters. The cam in this engine is pretty damn mild for a 383 but I don't plan on losing the engine or pulling the heads over a failed lifter. That leaves me with Morel and Johnson lifters. What I hope to make a decision on after talking to Tony is whether to go link bar or keep my stock lifter trays, and whether to go with a short travel lifter or not.
Short travel lifters are great for high RPM stability but they aren't the greatest for daily driving. You also have to be accurate with your pushrod length measurement to +/- .005. That isn't as easy as it sounds when you are talking about measuring a hydraulic lifter. Morel 5206's are link bar, regular travel and they run about $550. The Johnson 2116LSR are a slow leak down standard travel link bar and they run about $750. It's a lot to pay for a set of lifters when I could buy a set of LS7's for $118 but the peace of mind is worth it.
With either lifter I'm going to have to measure all 16 pushrods and order a set of custom length Manton's if I want a stable, quiet valvetrain. The preload window on these is about 1/4 of LS7 lifters (.050" vs .200") so they aren't very forgiving. That's why I can't measure for PR length until I get the right head gasket in. This is going to be an optimized build, not some off the shelf shit thrown together. I'll make a thread when I start measuring shit.
EDIT: First line
