I have an LQ4 with an LS1 4L60E, TCI said I can't use their flexplate because it has too much clearance from the block to the crank. They said I should use the factory flexplate but I need a SFI approved flexplate.

 

Help bump!

 

I used a Speed Inc Flexplate, longer bolts and spacers on my LQ4/4L60E Combo. Im using a Fbody LS1 4000 stall tc from transmission specialties.

Just make sure that your converter to flexplate clearance is between 1/8" and 3/16". Jegs has some nice shim kits that'll get ya close!

 

Thanks, I was getting no where on this.

 

I am using the TCI that was on my th350/ls1. the only difference is that I am not using the spacer that came with the kit. Im using a billet vortech converter
