351C efi

Weiand (Holley) makes adapters for any 302 intake to fit a 351C

so does www.pricemotorsport.com

Then you can use any 302 ho hi po aftermarket efi setup
on a 351C.

Hey that is a pretty good price (even in US $$) for the lower intake manifold.

Just Adapters

Those are just adapter plates, you have to still have the lower manifold. Weiand intakes (www.holley.com) may have a lower price than Price but check them both.

I think I've got the link, email me if you can't find it on the Holley/Weiand site.

Whoops! Weiand has adapters to fit 351C intakes on 400m engines, NOT 302 intakes on 351C's. Sorry. Looks like Price is the only game in town on that. But some of the hi po 302 efi intakes like the Ebock Victor type should work well on 351C's - depends on the 351's level of perf. if even the hi-po 302 intakes would feed it. Course, they feed very hi-po 347's pretty well.

Does the M400 have the same heads? Or same bolt patern ?? I thought the major difference was deck height o/k that will change angles etc but machining will true it up for lower deck height/ narrower valley of 351 ??

400m Difference

400m heads are essentially 351C 2bbls, but with worse exhaust ports. The "good" C's bolt right on. However, with the block being
higher, the intake manifold mating surfaces are farther away from center each side - I think the spacers are about 1/2" thick or so.
No way the decks could be machined that much.

Here's some 400m info just for S's & G's

So price do a unit to bolt a 302 windsor efi setup onto a 351 cleveland?

Does anyone know ballpark prices for a setup like this?

Would love pete's (xr9ute) setup, but unsure of the flexibility of this tweecer setup in regard to running tt.

I mean machine the spacers / adapters for they would be wider from the 400 [10.297] higher deck height and need to be narrower/ thinner on 351[9.206] block...So there is some meat to machine down to narower block..

Wrong Direction

OK, now I see what you mean.

The Weiand spacers have nothing to do with 302's.
They are for putting 351C intakes onto 400m blocks.

The Price website is www.pricemotorsport.com, they have
their prices listed in the price list.
