Question on carb and manifold combo? - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

Hi.I'm new to this forum,but,after reading hundreds of posts,it sounds like you guys are quite knowledgable.I'm from N.H,U.S.A.and noticed that a lot of you are from Australia where the Cleveland still reins.My question is what,with the specs I give you, would be the best combination carb and manifold I should run for a strictly street rod?
I own a 1972 Mercury Cougar with a transplanted 1970 351C with 4V closed chambered heads,flattop pistons bored .030 over,apprx.10.7:1 -11:1 compression ratio,a mild street cam(204In./214Ex @ .50 dur.484 int./510 exh.lift) with a stock dual exhaust and FMX tranny.I'm presently running an Edelbrock performer 600cfm carb on a stock 4V cast iron manifold.
I'm thinking of purchasing an Edelbrock manual choke 750cfm carburetor and a weiand 4V x-celerator manifold.Do you think this combo would be too much for what I'm running?
I appreciate any info you could give me.Thanks!

Welcome to the site. I wouldn't change manifolds,the standard manifold can b used even for a much larger cam. Carb wise a 650dp would be max to go to. This would then give u some room for more motor improvements without killing your fuel economy now.

I agree, the motor would benefit larger cam, weiand, even 750cfm be good for more top end.

i'd go with a 650DP, as for intake you could wait for the new edelbrock air-gap,
maybe a weiland with a 1" 4 hole spacer, or have a look at http://www.torque-power.com.au/

Thanks guys for the help.It sounds as if I'll stick with what I've got until the time I decide to change cams.That will have to be after the paint job.

For what it's worth with the small cam you have, good idea to wait until you do the cam change. Your stock manifold would be fine with that combo.

Welcome to the forum. You must be starting to defrost up there in NH by now!

Yep, predominantly aussie guys on this forum. Here's another Cleveland forum but in the US, which would be handy when looking for engine builders / parts suppliers etc in your part of the world.

You guys down under don't see much snow I bet.I could have shipped some of it to you.We got a S&!Tload of it.It's almost all gone now with temperatures in the 60s this week.Anyways it's about time to take the bomb,as my wife refers to it,out of the garage and start having some fun.Thanks again!
