I have a 351 in a xe esp its a manual with the standard diff. The guy i got it of had the motor rebuilt by Miick Web. He put in a cam (crane-h288-2) but left everthing else stock (carb, intake and exaust manifolds etc). The thing dies at about 4500rpm, what is good combination of parts to wake this thing up?

For a starting point, is your 351 4v or 2v? And did he match the springs/retainers/locks to the Crane cam? When you say dies, does it just act like it runs out of breath and doesn't rev higher or does it feel like its fluttering or popping or floatin valves?

Sounds like what stock XE clevos do.. So I would doubt you have anything other than a stock cam also.

Only other thing could be happening is an ignition breakdown and a dyno test would tell that.

If the motor is in good condition (ie doesn't need a rebuild), suggest you do the usual things such as carb, exhaust and inlet manifold first. Then a cam change with a bit of head work.

I agree on this, if it's got the cam stated it would barely be working with the standard setup. Go intake carby extractors with a good valvetrain and head work. Should spice things up a bit. Just need the $$.

I took of the restrictive stock air cleaner a replaced it with an open element type. Car now revs smooth right of the tacho. Power feels like it drops of after 5,500.I plan on fitting extractors, allready has twin 2 1/4" system any recomendations? I also have a holly 650 vac sec and a 750 dp, wich should i reco and what manifold do you guys recomend?

falcon coupe

I would recomend a weiand accelerator manifold, the 650 should be ok with the standard cam, if you go a big cam the 750dp will be better.

Rossco

Thanks falcon coupe. The cam is not standard its a crane cam part no 524421 on their web site. Is this a good cam for a mild 351? Would the 750 suit this cam?

falcon coupe

I can't see that part number on the crane page, can you list the specs @ .50"

Rossco

Go to crane web site enter 524421 in product search - part number. Then click on cam number on the page that comes up after the search.

Ok, it's not a huge cam but i think the 750dp would be better with it than the 650 vac, anyone else agree ?
