I've actually tried this on a 4500 Super Victor intake to a 4150 carb thought it ran good untill I got tired of looking at the spacer and changed to a Victor JR. Picked up almost .08 on the track. Even better I put a dart/wilson on after that and picked up another .04-.05 I was shocked. Figured I was getting the funnel affect and it would help it also but guess not.
I only used it because that was the intake that I already had...I have no trouble buying a new one if I thought it would run better.

Do you think maybe the victor junior was just a better manifold for your motor or do you think it was removing the spacer that helped? I was thinking a Super Victor would be good on my 540 but I only wind it to 7000 so didn't want to go too big with the intake.
I think the victor jr was just good on my small block. Now my 548 I had a sonny's brodix on and switched to a super victor (it was a td block and I wanted to get rid of spacers) and it slowed down .05 in the 1/4. I'd of love to tried a 454R on my motor I am sure it'd of been the best intake for the job. I think you'll find the same with your motor, speaking with several on these super victors it seems they like 565 and above or very healthy 540/555. The 454R seems to be what is being used a lot on 540's now they are a nice intake and you can normally pick one up here on RJ used for the right price. $125-150 I paid $90.00 for mine off ebay.
