Where are you getting the bell housing, starter, front belt system etc? Pretty much the marine parts.

Bell housings and front mounts I have as I kept them from when I parted my blower motors. Using ict billet low mount truck spacing alternator bracket and ps. Ls1 camaro pump. Starters and alternators frim late model salvage yard. All super low mileage stuff. Crank driven water pumps I alrady have using marine power mounts for ls. Moroso remote thermostat is in the works now for cooling control rather than hardin.

I ran a set up very similar to that when I first put the engine in. A brass crank mount pump into Moroso LS/BBC water pump adapters and a crossover into a Moroso remote t-stat. I was not happy with how it cooled the engine. Temps were very erratic. I ended up going with the Hardin setup, but I run it as open cooling. Yes, it was expensive, but it works and looks great. Now, I am thinking about going with a ProCharger on the engine, so the Hardin stuff will have to go, but I have been talking with a guy who makes a really nice bracket that bolts into the stock LS A/C location as uses a Merc style raw water pump. Using that, you can run stock style accessories including a circulating pump. He is much cheaper than the Hardin pump as well. Might be worth looking into.

I have it figured out where I can run the circulating pump with the moroso thermostat housing which will keep temps consistent. I will draw it up tonight and post it. Very simple afgordble setup. No need for block adapters. The crossover is why you had inconsistent temps.

Just playing. 950's would be my first choice on those ls builds among many other within that hp range. That's what Dennis r used on his and once set up right to my understanding they worked out well. They were new PS 950 carbs originally built and calibrated for 454/177 sc builds. Dennis put the coon tune on them tailored to his builds.

Yep. 8k miles on one set. 20K on other. Game on. $120 for all 4 vs 5-600 d585 junkyard coils too. Everything else brand new though

I thought marine starters and alternators were sealed units?

I recently had a friend engulfed in flames when the key was turned on a boat that was meticulously maintained with all marine components........

Marine rated starters and alternators aren't that expensive and cheaper than a burn unit vacation or a funeral.....

Just sayin........

I went with marine grade starter and alternator on mine. That being said, the stock LS stuff is sealed from everything I have read.
