351m 4 barrel intake
can you put a weiand 4 barrel intake on a 78 model 351m that came stock with a 2 barrel. i thought i heard somewhere on here that you couldnt do that because the heads were made for 2 barrels or something like that. if it will work what size carb do you suggest, it's gonna be used mostly street and im thinking of putting a mild cam in it like a comp cams magnum280 with a 2800 stall.

Yes you can put a weiand 4 v intake manifold on with prolly about a 600 cfm carb.
Try looking at summitracing.com or jegs.com for some of there combo deals, to same money and get everything that matches with out the hassle of searching all over.

sparky69, that site was kind of confusing, which intake manafold performed the best. Most of the time it looked like Edlebrock did the best, but I am alittle tired, amoung other things, so which did better?

The PO of my Edelbrock intake had horrible sealing problems with it. Massive amounts of sillycone around the carb base. What he didn't know was that the manifold had a 1/16" dia pinhole in the casting 1/2" below the carb base. I drilled out the pinhole and sealed it with JB Weld and a blind pop rivet that was formed into place after installation. The repair is so good nobody will notice. Go With a Weiand. The only reason I went with an Edelbrock was that I got the manifold for under $50.
Some other manifold dyno tests a ways back have shown no difference in the Weiand and Edelbrock designs for this engine. Any differences shown in this test are well within the margin of error for the tests.

I thought weiand would be the better choice in the first place. I was looking at a weiand intake and holley carb combo, among other things.

Not trying to start a edelbrock holley fight, but I thought if you tuned your holley right the 1st time and you stay in one altitude you'd be fine.
At least that's what I've heard from some people, but I've also heard they're a peice of *****. I've heard both for edelbrock parts too.

It comes down to personal preference. I use Holleys on all the high performance engines and Autolites on the daily drivers.
