I am currently trying to decide and efi manifolds. Everyone is quick to say Fast 92mm but I thinking victor jr. efi with an elbow. The engine is a ls1 with heads and cam in an 87 monte carlo so I plenty of room under the hood. Can anyone give me some definite answers like dyno tests or personal experience. I have an LS6 intake on there now.

the Vic Jr's are cut to use o-rings on the heads-some have had trouble cracking along the bottom lip, mine did-i sent pics to Edelbrock, they never responded, so i just welded it up (2 runners)
one thing i noticed when i pulled the intake, i had used NAPA o rings (their orange), cause they were cheaper than GM-they all had deterioated, so i switched back to GM
