GMC 1500 LS1 swap specific questions

[Blasphemy]

I'd stick with the truck intake because I've seen superchevy.com do a build and found that the truck intake makes more bottom end power which is what you need for the weight of your truck and the ls1 intake makes more power in the top end. There isn't a huge advantage to switching to the lower profile intake. If you're going for aesthetics, I'm sure a true LS enthusiast will know what they're looking at when you pop the hood, regardless of intake.

Yea i knew that it'll getting tuned. i just really dont like how sh**ty the truck intake looks, and i dont care what someone else thinks when they see it,(i live in wyoming, theres like 3 of us that know what were looking at lol) but what i think when i pop my own hood. if im not losing 25+ hp to run the car intake id rather do that because yea it looks way better than that tore up truck intake or the vortec engine cover that came on it. its just my preference i guess, i understand that power wise the truck intake is the smart choice, but this isnt a racer, id rather it look good when im all done.

I swapped the LS1 intake onto my LM7, although mine is boosted so I dunno how much of a difference in power there is. I will likely switch to a sheet metal intake in the future anyways.

The mods I had to make were:

- an idler pulley relocation bracket(cut off where it currently is on the alternator bracket)
- Turn the water pump neck so its more forward facing(turning it wasnt as easy as I thought it would be)
-Cut grind out rear of alternator bracket to make room for steam vent tube
-Use 90deg AN or JIC fittings to fit crossover tube(if aftermarket fuel rails)

Note! Be very careful with your belt selection with the new angle of wrap on the idler pulley and tensioner! Alot more stress is out on it. I've broke 3 tensioners, but have sorted out the issue
