Im using 2008 ly6 blocks. Chose these due to priority main oiling being gen iv which requires vvt delete. I went iron because of strength( found out how much a aluminum ls2 could handle the hard way at 22psi boost in the gto). Way less cylinder distortion. Also much less swing in bearing clearance while waiting for blocks to warm up. Msin reason is raw water cooling. I do not run in salt and am saving an astronomical amount of money by avoiding closed cooling. Mainly out in havasu and Phoenix.

Sniper efi is 800cfm. Pro systems venom 1050 annular is 980 wet flow cfm. Since I am running a dual plane and essentially cutting the carb in half I see the carb taking the cake by a long shot up top and the annulars still giving decent manners off idle compared to a down leg. I know the holley sniper is the same software as I use on my gto except I use the dominator efi. Very good tunability and self learning. Also the snipers ability to run without an o2 is a big plus. But the question is how much am I leaving on the table. I will also be running a single plane on my dyno run to see comparison

240lbs in anything is drastic, especially when chasing every mph. I couldny justify the added cost and have already had the big hp blown big blocks in it and went way faster than I am comfortable at. I figure 110-115 is good enough for me. The extra weight, which is 93lbs per block, would give me another maybe 2 mph. Now being your doing a v hull the century mark is harder to come by and every mph counts. The p29 is a damn good boat. Keep us updated.

I just ordered a set if those oil pans. Thanks for info.
I also bought extension boxes, raised the drive height, and some more weight savings throughout the boat.

You will like tge pans. For the money zero complaints. I did get mixed opinions from them on whether or not to use the factory windage tray as well as the pan windage tray. I will be running just the pan initially. I honestly dont even think with having to soace the windage for stroker that it will clear the pan windage. Hopefully you got a goid deal. I have an account through them and could have gotten you a break.

Do a google search for ls engines in road racing, which is extended high rpm running like a boat, with the emphasis being on oil starvation and you will find all the info you can read. I should be fine with 10.5 oil capacity but no chances considering im already in there doung it. I may even run an accusump for when I get off the gas hard after long run and cold starts. Piece of mind. Out of all the toys I own the number one and only killer has been oiling mainly on the main bearings. It is my kryptonite.

Thanks. Should be ready for paint tomorrow other than that waiting on pushrods. Then onto wiring we go and reengineering some tails still pondering on pro systems venom vx carb 1050 annular or holley sniper efi. Carb more power less dockability. Efi less hp more dockability slight gph decrease. Decisions

I think you'll be surprised by the dockability of the carb'd motor. I'm not running a carb anywhere near as big as yours (AED Holley HP750) and I'm running a single plane Vic. Jr. intake, but with the adjustability of the timing curve, my boat is awesome at low speeds around the dock. Better than my Merc 454 was that came in the boat. Thing also starts and runs like its EFI. I can leave it parked over night, go down to the dock and not even touch the throttle and it fires right up instantly and idles perfect.
