Suggested Mods when LS1 is out of car...

[Mark B]

Hey guys,
Ive been going back & fourth with this. My car is due for a new engine. The little 305 just cant hang with my speed needs. I have been debating on either a low mile LS1 or a custom built 355/383. I have pretty much decided to go with the LS1. I will have close to the same power with all of the driveability & comfort of a new stock engine. Plus I can always do mods ot the LS1 to get more power. Before I put the motor into the car, I was thinking of what mods I should do when the motor is out. The only big thing I can think of is a cam swap. Anything else you guys can think of?

Make a 382 LS1? Cam, heads... you name it. You may as well do headers too.

Cam suggestion: G5X3 from LG Motorsports

Ho much do you want to spend?

[Mark B]

Not too much. Mabey 1k?

I was already counting on getting headers. They are not included in the 1K

Dumb question but do you have all of the elctronics to make a LS1 run? Computer, harness, 4 O2 sensors, etc etc? Oh and I'm pretty sure an LS1 will not bolt to a 700R4 tranny.

That's just barely enough to do the cam swap. If you get a 2000 or older model LS1, you will need to upgrade the oil pump. There was a factory flaw in the pump those years. Supposedly GM corrected the problem in the pump in 2001, but if it were me, I would still upgrade to a better ported oil pump regardless since you are already there.

Figure in a new valve spring kit as well, and if it were me you might as well spring for a better timing set with the new cam. It is not neccesary, but just a good idea.

Check out Thunder Racing, LG Motorsports, or Combination Motorsports. They have pretty good deals on complatet cam swap kits.

I will get all of the accessories, ECM, harness, etc. I also will be getting a complete T56 with it!!!! Cant wait!!!

If you don't mind me asking how much was the engine and components?

Doesn't the 3rd gen. cross member need some fabrication, I beleive there was power steering pump clearance issue, it has been done though and it looked clean.

A 50k mile setup goes for $4000-$4500 on E-bay. Luckily one of the places that sells them is local to me, so I can save shipping. The Alternator & A/C Compressor hits the frame rail. The alternator is an easy fix, but the Compressor takes a little fabrication.
