Ls1 Chevelle swap Q's
Alright guys, I have a 71 Chevelle fully restored that just threw a rod with the new engine(all done by previous owner). I have an 01 SS I just picked up with 150k on it and I figure ****, instead of selling that I will just put it into the chevelle. Basically I will save money putting the LS1 in the chevelle and selling the SS as a roller then just rebuilding the 350, which helps the whole broke 19 y/o budget thing.
It's a stock LS1 with Pacesetter headers and I will be using the SS auto transmission also.
Will Pacesetter's work for my swap? Will the auto slide right in and bolt up? Will the drive shaft fit? What engine mount plates do I need?
Any other pointers to go along with it? Also can I use an in line pump? I did the in tank thing on my 80 T/A swap and it never did work right.

I used the walbro inline pump with the corvette filter/regulator combo. I'll be posting pics of it soon on my thread(I'm nearly done with a 69 442 LQ9'T56. I simply couldn't afford an intank setup. The auto trans should bolt in, driveshaft length depends on how far back you sit the motor.
and
Good luck man, those wheels look awseome with that paint.

A good fuel tank alternative is a 94-96 Impala SS plastic tank. I believe it is 23 gallon, so you get increased range. It nearly bolts right in. I made spacer/extenders for the tank straps, and made a hole in the trunk floor to tuck it up tight. A BBK intank pump works great. You will need to recalibrate the sender or change gauge. If you need them I can provide pictures.

I would hate to part out a good SS, but that is your choice. But yes.. parting it out and selling off the roller or parts would cover the cost of the swap or HP parts, But at 150k.. I would spend some of that on refreshing the engine/trans and anything that is already high mileage on the Chevelle (suspension/rear). You can also use the LS1 brakes on the Chevelle with adapters.
Yes.. Using a late model B-Body tank and a Racetronix B-Body kit (pump and wiring harness) is a great alternative to the high cost tank and complicated modifications of the OEM Tank. I have done this in my swap also. You should not have to recalibrate the sender.. it is a 0-90 ohm which should match up with your Chevelle gauge.
I looks like the prior owner swapped a 72 grille.

I did an external pump on my 68 corvette, it has starvation problems at under 1/4 tank. It's tank is deep though. My 72 442 tank is shallow and wide. No way that wont have problems.
I went with the 96 caprice tank. It has a built in sump and I upgraded to the racetronix pump/wiring. Works great except you got to fill it slowly to prevent backsplash..

Hmmm.. Garys_68.. i have no filling issue.. I always pump at full rate at the pump ?.. how is that vent tube that goes from the tank to the filler neck ? did you use it or is it obstructed in venting ?

BRPhotrods sell adapters kits... you can also find them on eBay (there are others vendors also).. They front adapter kit for both Disk or Drum brake spindles. I picked on up for my Nova swap. Need to pick up a rear adapter next (about 1/4" spacer is needed).
There are a few threads on doing this.. suggest you research "LS1 Brake swap" or "adapters".

Just a suggestion.. I have a Genesis radiator.. aluminum hand weld that works beautifully in with my Ls2. There's no reason why they wouldn't make a gas tank as good ...

G/l with your build. Nice seeing the classics come back.

This covers the rear. C5 stuff works as well in place of fbody parts. http://www.sloppymechanics.com/archi...entry_867.html

I'm not the only one with that issue. Right now, my vent line is capped, but after reading post 34 from the link below, I have not Ted it into the neck.
What's your setup look like?

the pacesetters should work. The drivers side kicks off at a funny angle, Just cut the collector on the 3" section and angle cut it so the header shoots straight back. I did this with a set of hooker super comps for a 2002 camaro before they ever made swap headers of the chevelles.
