I have a Paxton I am installing on my carbed 351 this spring. Before I do, I want to upgrade my intake. My intent was to go with a polished Performer RPM intake. I have heard that that isn't the way to go. Any imput?

vfast

what kind of boost?...what else do you have..need to match the intake to the rest if we can. an airgap would be nice as would a victor jr.

you want a single plane not a dual plane, like vfast said a victor or torker would be the way to go

My plan was to go with th polished air gap, nut a friend told me his friend put one on his blown 351 and it caused him more problems than the performer he had onit originally. As for the cam, I was going to use a Performer RPM (496/520), due to convenience, but after talking to another friend, I question the performane of it with the combe. My Paxton is an SN-92 with no upgrades. (5-6 psi. I believe)

vfast

fast..well first that's not alot of boost...are you going to use a roller cam? tell me about all your mods and gear and what you looking for I'll then can rep 2 cams for ya...
I would into going 7-8 psi to make it worth your while. what carb are you going to use?

i dont have a lot of input on the blower, but the combo of a victor jr and rpm cam does pretty well, i have that in my 351 and it has good power through out the rpm range, run mid 12's with cast heads and long tubes, thought it might help</P>

Here's what I have: </P>


85 351 w/ stock heads. Performer cam. 1 5/8s shorties. 2 1/2 exh. Block is decked, squared, and bored .030 over. Stock (exc. cam) rebuild w/ hypereutectic 9:25 comp. pistons. Running 3.73s. Right now its a stick, but an auto is going in when the snow goes.</P>


On the shelf is my SN-92 and a set of Performer Aluminum heads with2.02s. I would like tochange the cam and intake to make the blower work right with the heads.</P>

Well I won't go with the single plan intake atleast withmy experience. You have to have wayy to high of a RPM for power like past 4,000. And if this is going to be a street car, then that is way to much for it. I would go with the air-gap my dad has that on his 351W and it is designed like the Victor Jr., but for the street it is alot better because the RPM for power is 1,500-and up. So whatever you decide, you have to think if it is going to be a street machine or a car at the track. But with that combo it looks like you are going to be more on the street car. And your pistons I have one thing to say about them, they won't last to long with a blower because they are hypereutic which isn't that strong for a blower. Forged pistons can handle the abuse better.

mustang88....his has a s/c so a daul plane is not wise..it may be ok in your dad's N/A set up....some single plane intake are good from 2200-6500 which the old torker is...the 302 has alot of grunt in the lower end anyway..but lack punch in the upper mid-range...so with moving the rpm range up 500-1000 it help with tractions an the like..<img border="0" src=smileys/smiley2.gif border="0">
