I have a TC hood, but I'd have to hack it all up to make it even come close to clearing....it used to hit the top A/C bracket on the driver side scoop...now with the same accessory drive...even if I took the scoops out and cut the scoop brackets off....but that'd look terrible...lol.

Really? Mine came close, but NEVER hit when I had A/C....

Interestingly enough, a 302 block with a 1 3/8" spacer and a Trick Flow manifold clears :hick:

I had no issues with the TC hood on my 86 cougar near the intake. The ac bracket lines up perfectally with the lowest part of the scoop. If your motor mounts are bad or worn out, when you rev it it will bust the scoop right out.

Now you've got me wishing I'd done the 351 thing. Unfortunately it came down to T-5 swap or 351, and I chose the T-5. I had a perfectly good (in fact, it was near mint inside) roller 351 that I was gonna use, but instead I sold it to buy the T5 swap stuff. Oh well, the T-5 came with an HO intake and 19-lb injectors, and I've got some E7's and a DA1 on the bench, so once I scrounge up an HO cam I'll at least be able to upgrade my lowly SO to HO spec...

I'd never even heard of the Bronco adapter thingy, else I may have considered the T5 AND the 351. It was the cost of a 351 intake that was my chief concern. I had always wondered why nobody made a 351 lower that was compatible with the HO upper, but I guess the adapter thing takes care of that...

*EDIT* Oh, and about TC hood clearance: I had to remove the top A/C bracket from mine (stock SO 5.0 with stock engine mounts). When I had the hood on without the scoops you could look into the driver's side hole and see that the top bracket would definitely have hit the scoop, had the scoop been installed. I've never bothered checking to see if the Chuck mounts lowered it any.

Aftermarket vendors make 5.0 type intakes that will mate to a 351, but you're gonna pay.....

thunder chicken- the price of a 351W fuelie intake really slowed this project down...I had just cut apart the truck upper and mocked up a box style plenum and had some of the materials cut...then I stumbled upon the $100 BC Broncos adapter...saved a lot of time. I have no problem building a box style intake out of any OE upper, I've done it plenty of times before...It just takes more time now because I don't have access to a nice heli-arc welder(often referred to as TIG- same machine, significantly different settings).

The intake clearance wasn't the issue, as you said it was the AC bracket...with Chuck's mounts it was that bad, probably could have just cut down the stud on the scoop bracket...with the stock mounts, it was STUPID.

V8Demon- did you have a bird/cougar FEAD or a mustang FEAD? There is a pretty big difference between the two from what I've seen.

When I had the A/C, all the bracketry was standard Catbird equipment AFAIK. I ditched the A/C and swapped to a Mustang P/S bracket and the Ford A/C eliminator kit.

I've never really compared the A/C brackets between the 2. I would assume that the Mustang one would sit lower for the needed hood clearance -- if there is a difference between the brackets; again I don't know. I know for a fact if I dropped my motor in a Stang, it would need a cowl hood due to the intake spacer....

Yeah, I think the fox mustangs have a little lower hood line...on the mustang FEAD, the p/s pump is placed a little lower and much further outboard and the A/C compressor is dropped a bit.

I'm still trying to figure out why everybody was saying a smaller booster was necessary...again, possibly a mustang only thing?

Thanks for the inspiration Don. You guys don't mess around. Lit a fire under my butt to get my car done. Just doing the Mach 1 springs for now. The 351 will have to wait a bit

I think it was a great job, gives lots of info for the would be swappers...

Interesting about the TC hood inserts with a 5.0(no doubt a 351 would have issues), my A/C bracket just barely touched the D/S insert... I trimmed the bracket to be sure there wasn't a problem...

Yeah, I mowed my bracket down too on my old 'Bird...the disappointing part of it was I had molded my scoops into the hood and learned the hard way after it started cracking the skim coat of filler...I love the TC hood, but hate the seams around the scoops.

Hey Crash, you'll get it done, just pace yourself man....apparently some people took notice of our work that weekend...had a guy knock on my door the other night asking if I could put a reman 351M in his '80 F-250...lol.

I didn't realize that actually was enough hood clearance. Looks like I should be looking for a roller 351 shortblock! How much heavier is the 351 rotating assembly than the 302(347), anyone know?

I dunno exactly but the main journals on a 351W are huge, 3" vs 2.25"...

I'm thinking it's an easy 75-100lbs heavier than a 5.0. Doing a 351 swap isn't really that bad at all...but the price of things tends to creep up on you if you're not prepared...all in all, not too bad and an excellent end result...just wondering how long the T-5 will live behind it...lol.
