I am in the middle of a ls1 t56 swap in my 1979 z28. I understand its best to get the motor back to the firewall as far as possible to keep the nose of the car lighter. Without 1 inch setback mounts will a f body oil pan clear the cross member and are there headers on the market that will also work without the setback? The reason I ask is because of the pooer on the t56 is future back and I really want to use the factory 4 speed console, this means with out the set back mounts I will be that much closer. Thanks in advance for your help.
