Question

OK Here's my dilema... I'm nearing completion of my 454 engine buildup. I've already purchased and installed an Edelbrock Performer RPM manifold and Edelbrock 750 carb. I've also purchased the proper engine frame mounts.

Will I fit this beast under the stock flat hood on my 67? Edelbrock's site says NO!

Thanks

I have a 67rs I just put a 454 in with the same intake as you and a Holley 750. With a 14 inch air cleaner and a cowl hood the hood will not close. With a smaller air cleaner it should work no problem, dont know if this helps you or not. I can close the hood without the air cleaner on and I have about 1/4 inch between the top of the air cleaner stud and the top of the cowl.

I have the grated SS hood on my 68, which I believe allows a bit more room than the stock flat hood. I'm sorry to say I bet you don't get that intake under that hood with an air cleaner. I hope I'm wrong. I have just made an intake change, from a Torquer2 to a GM cast iron Holley 4 barrel intake. I mean it takes it all, with a drop base air cleaner. Goo luck.

Unhappy

Oh well, I guess this manifold is going back. On the big block I measured from the motor mount long bolts to the top of the carb and came up with 19.75 inches. And then did the same on the small block, which is in the car. It measured just under 20.00 inches to the underside of the hood. Too close to tweak anything.

I have to consider a lower intake, bummer!

Thanks for the replyís.

I went through the same thing as you. The combo will not fit. I ended up getting a cowl hood and I still need the drop base air cleaner. I built my 454 from scratch and I could not stand the thought of putting a cork(restrictive intake manifold)on top of all the hard work and money I spent on the motor. Looks killer too!

hey calebs,i have solved clearance issues like yours in the past by using a castle style bolt(i think thats whai it's called)instead of a stud.
the bolt has a round top and a square shoulder under the head,it screws in flush with the air cleaner top and looks pretty smooth too!just find the right thread and cut to length.screws in with thumb pressure and i've had no problems removing mine.it will save you 3/8 to 1/2"compared to a wing nut.

I currently have a Eldebrock C-396 intake & a 750 CFM Eldebrock carb on my 396 & a drop base 14" Factory air filter, my air filter top rubs the hood pad, I'm getting ready to change to a Holley 750 Double Pumper Carb, What would be a good intake to use? I have oval port heads, a comp cams extreme enegry cam, a SS hood.

Question

Has anyone tried a Weiand Stealth intake? I measured my old Holley Cast Iron Intake today & the front of the carb pad is 4 & 1/8" & the rear of the carb pad is 5 & 5/8ths high. The Stealth measures 4.75 front & 5.75 rear. this is suppost to be a real good intake if it will fit with no promblems. If not could one be machined down to the stock specs?

What drop base air filter housing are you using?

Question

Okay, now I really confused! I just found out two things:

1) I canít exchange my Performer RPM manifold for the std Performer without a 20% charge (Summit).
2) As I mentioned Iíve read on Edelbrocks site that the RPM wonít fit under the stock hood. However, the measurements posted are only different by .6 inches.

From what Iíve measured it appears neither will fit. When referring to Big Block Camaros, did they come stock with a cowl hood? What Big Block hood/manifold combos work?
