!!! !!!

... damn ... does that bring back memories ...

Do you have a CASTING ID PN to help ID?

[rockfla]

What you see is what I got, I don"t see any number on it other than what you see cast into it.

But Bush Performance Engines in Fort Smith, Arkansas, has taken the concept a step further by bringing back the Clevor engine, a package that mates the large intake ports of the 351 Cleveland heads to the 289/302/351W blocks for affordable small-block performance. This is the next step up when 351W heads just don’t get it done.

Performing the swap requires some minor machining and a special intake manifold to mate the Cleveland-style heads to the Windsor block. Back in the ’80s, B&A Performance offered these manifolds in both Street Boss (dual-plane) and Track Boss (configuration), with versions for the wider 351 Windsor blocks as well, but manifold production was discontinued several years ago. Bush Performance Engines has picked up the rights to produce the manifolds so they are once again available, except for the 351 Street Boss, for building street or track versions of the Clevor small-block

They made the intake as CLV 2V and 4V (cyl head runners) and 289/302 and 351W spacing as well as single and dual plane. I can see yours is dual plane. Why they didn't include a CASTING PN to differentiate them is a surprise to me.

I've heard that they were 2V and could be ported to 4V needs???

SO...is that two different intakes???? One for 289/302 and one for 351W's OR one size fits ALL????

[KULTULZ]

Four intakes -

289/302 SGL PLANE
289/302 DUAL PLANE
351W SGL PLANE
351W DUAL PLANE

Based on the few I see sold on the internet, I'd guess ballpark estimate around $400 (give or take).

The CLV 2V head was preferred for street as the 4V heads were a bit too much w/o modifying the rest of the engine. AUSSIE 4V heads were popular and there were intake runner special gaskets to speed up flow for 4V heads.

This was all old tech. FORD finally came around with free-flow WINDSOR heads and with the use of EFI made the CLV modification less popular.

But they would run. I had a 73 351CJ in a RANCHERO that would flat get it done.

SO.....ANYONE have a tried and true way to tell IF what I have is for a 289/302 OR for a 351W??? Maybe a width measurement??? I think what i was told was its for a 351W BUT want to make darn sure before I send it down the road and not horn swaggle someone!!!

The Aussie Cleveland heads have 2-bbl. valve sizes but 4-bbl. combustion chambers. You do not want to use US 2-bbl Cleveland heads; the combustion chambers are too big.

Is it possible they only made the manifold for the short deck block (289-302) and had spacer plates for the tall deck (351W)? Just looking at the photo, I'd say it's for the small engines. Compare your photos to a C9ZZ-9404-C original Boss 302 manifold. A 351C manifold is considerably wider

[ponymare]

To tell, turn the manifold upside down, measure where the manifold rests on the cork gasket, if 5 inches, it's 289, 302, if 7 inches it's 351-W, 351 C engines have a dry intake.

[5851a]

Yep, just went to attic and measured a 351W stock intake under Tstat 7.25 on the front china wall surface.

Thanks Ponymare and 5851A. The fellow I am selling it to has both a 302 and 351W SO he wants it either way!!
