Marine Intake

L31MaxExpress · Dec 1, 2022

I will verify the Bosch number on my MAP, but this is what is crossing as a replacement for 885165. Also note to future self, the MAP did not like being soaked in brake cleaner when I cleaned the used intake prior to swapping it on the 1st time. It may have been DOA when I got the intake, but if not the brake cleaner killed it.

That would be super helpful. I’ll take all the help I can get. My cam has LSA of 112. Would you recommend a different cam, or do you think the one I got is going to be drivable in day to day reality?

Do you have the Lunati part number?

I googled the Lunati and those durations and came up with this stick.

EFI Hydraulic Roller Cam - Chevrolet LT1, LT4 279/287

Hydraulic Roller Cam. Has greatly improved power and torque over stock cam. Good idle.; Advertised Duration (Int/Exh): 279/287; Duration @ .050 (Int/Exh): 213/219; Gross Valve Lift (Int/Exh): .447/.471; LSA/ICL: 112/108; Valve Lash (Int/Exh): Hyd/Hyd;

With a good tune you will not know it is not stock as far as driveability goes. I tuned my buddies Yukon with the slightly larger 218/228 @ 0.050, 0.503 lift Bare Bones Hotcam. With a 2,200 rpm converter it ran great even with the old black box. I have tuned the Melling 220/224 on a 110 LSA in one with a Black Box too. The idle was starting to get pretty choppy at 750 rpm but it was smooth off-idle and had good torque as well.

Oreilly should have them. Usually stock Accel, Standard and Felpro injector o-rings. Should be the same as a TPI or LT1, btt I do not have the manifold here with me to measure.

On thing you may want to do is play with shift points at light to moderate throttle and keep the converter unlocked until a higher mph. Other than that tune away, it will run nicely.

I have a Black Box, an 0411 and a P59 file that would be a better starting point than the factory tune for a cam like that one.

Upper plenum and throttle body are cleaned up. I did debur a sharp turn to make the entrance more radiused. It looks tappered because of the inconsistent depth of the material, but it is 80mm straight through now.

Nice work.

Same pics from underside, please?

I bought my 0411 from black bear. In the purchase questionnaire the cam was mentioned, but I hadn’t acquired an intake at that time, so I’m guessing it’ll have to go back for that adjustment. I’ve never tuned, nor do I have efi live. I was hoping to at least be able to drive it enough with a recording device to give black bear the true perspective. As of now they are my only tuning support. I also put in the form that I had long tube headers. My search for those has come up to the hookers, or the stainless works. The SW are specific to the extended cab wheelbase, and at 1800 bucks I’m not confident enough to gamble. They would be non returnable

See if he'll tune you with an autocal. That device will allow you to log data for him, and he'll send you a tune that you'll flash in with said autocal.
