I have a LQ4 that i'm wanting to change over to all ls1 bracketry and drive belts. i have some parts already i just need to know what all i need to do this.

i have f/body water pump, balancer, and the reason im doing this is so i can use an ls6 intake. Speartech no longer makes the relocation bracket and i don't want to fab up my own. anyone have any insight?

I Hope This Helps, I Have Done This Swap Before On A 6.0. There Are However A Few Bolt Holes On The Truck Block That Are Missing To Mount The Alternator. You Shouldn't Have A Problem With Them Missing. I Didn't

 

I'm getting ready to do this swap also. Do I HAVE to change the AC bracket and IF SO, will the truck compressor still bolt into the F-body AC bracket?

I already have the crank pulley, alt bracket, and PS bracket so I'm just waiting to make sure about the AC.

 

i used the following. first thing i did was drill and tap my block for the ALT bracket. then mounted up all the car accesories. for the AC bracket i used the truck one but i ended up enlongating my holes so it owuld line up properly with the crank pulley. you will use a fbody serp belt but for the AC you will need to get a belt. i at first used a LS2 TBSS belt for that AC but then realize it was to tight. i then wewnt to the parts store and told them i needed one about 3/4" longer and no issues

i have the belt avaible with only like 2k in miles on it. i dont htink i can use it since im going with a SLP 25% underdrive and will probably end up with a LS2 belt again

 

can I use the truck AC compressor on the F-body bracket?

 

no, i tried that and its not even close. i would of used the fbody ac but the plug is different and didnt watn to rewire so i just enlongated. took some time but it came out good and no issues with AC on or anything for 8k miles

 

damnit....
