302 street carb and intake manifold

[A05C]

im goin to be buying a carb and intake manifold for a 302 here either this week or next week, and i need some help.

im not sure which company to go with and what CFM would be good for a street/strip car.

i had been talking to some people and they were telling me that a 750 wouldnt be enough and still dont know of a good company that i wont waste my money on.

i plan on using a plate nitrous system eventually also if that makes a difference

anyone that can shed some light on this will be greatly appreciated

Thanks.

Need more info on your setup....

As for carbs... http://www.prosystemsracing.com/index1.html and ask for Patrick.

Intake really depends on the rest of your combination. But if you plan on spraying a bunch, you will need a single plane.

its goin to be a basic 302 right now nothing too extreme as of yet. i plan on building a 351w stroker.

basically im sitting on a 302 with an aod trans on it that i'll be putting in soon. i was thinking about going with the edelbrock victor intake manifold for a street application and the fact that its a stock motor that i wont be reving out super high or anything.

Don't make the mistake of buying a carb and intake now for an engine that's well in the future. You'll end up wasting money and power. If you're using this on a stock 302 you absolutely don't need a 750 and you surely don't need a single plane because you'll be out of RPM before it ever starts breathing.

Get yourself a Wieand Stealth intake and a 600-650cfm vacuum secondary Holley, probably this one right here: http://store.summitracing.com/partdetail.asp?autofilter=1&part=HLY%2D0%2D80670&N=700+4294925239+4294839063+4294919007+400178+4294 891681+115&autoview=sku

That's a 670cfm but they still run great on a stock 302 and will give you room to grow if you get a cam and GT40P heads or something.

Id have to agree with the above mentioned weiand stealth and carb, especially if your doing a small build, i know some people that have had quick cars using them.

I'd say for all but the nastiest engines that'll see street duty the Stealth is still the best intake available. You can still port the hell out of it if you need more flow and you'll still have the benefit of a duel plane intake. I ran a Victor Jr. for a while but that intake one BAMF and is really a race intake. You can run that thing almost to 8k RPM. The only way i'd go back to that is if i were running a blower or turbo or of course if i were building a car that the priority was to be a as fast as possible in the quarter and not so much on the street.

if i dont have to work the track today i'll be heading to jegs in c-bus and prolly pick up the intake manifold and carb as recomended abouve. i looked into it and that looks like the best for my application. if i dont get my suspension next i'll be buying a set of heads and a cam and a nitrous plate to have a little fun for a while

one more question has came up..

would it matter much to go with the X-CELerator or just go with the stealth?

stealth

what kinda fuel pump would be a good idea? a drop in walbro 255 for now and what about a regulator

[mustangboy]

If you are running a carb you won't be using a walbro drop in pump as those are for fuel injection. You will need to get a low pressure pump like a holley blue or something similar.

[A05C]

i didnt think it would matter as long as the regulator can get it down to an acceptable psi to work with the carb

[85_SS_302_Coupe]

That's the catch, finding a regulator that you'll trust to regulate the 40psi or so that the EFI pump puts out all the way down to about 6 or 7 that a carb likes. Personally i would never trust even an Aeromotive regulator for a job like that because if it fails you're going to burn your car to the ground. I saw a guy at Edgewater 2 years ago do it...he made it out 60 feet and his carb started spraying fuel everywhere (no hood) and it burst into flames.

The right way to do it is to sump the tank and get an in-line pump and regulator.

or get an 85gt pickup for intank and run a manual or electric pump
