im looking to get a little performance out of my car i just dont no exactly which one i need.......

i have a 84 camaro, it used to be a 305 but it is now a 78' 350....
i got the 4 barral rochester.....

the reason is my manifold isnt in to good of condition and i think it leaks out of the plate i put over the thing that i dont use its not the the egr because i use that.... but its right next to it...... kinda of a upside down rectangle

 

Are you looking to run a single plane intake? or a dual plane intake?

 

if it's fairly stock, get a spreadbore performer rpm. http://store.summitracing.com/partde...5&autoview=sku

 

WHATS THE DIFFERENCE BETWEEN SINGLE AND DUALL PLANES........

WELL MY MOTOR IS BORED OUT .30 AND I GOT A MILD PERFORMANCE CAM AND AND I RAISED MY COMPRESSION A LIL BIT...... IM LOOKING FOR SOME PERFORMANCE THO?????

 

A single plane intake feeds all eight cylinders from the same space or plenum under the carb. A dual plane splits the engine into two halves with two plenums under the carb - one is higher than the other, therefore the title "dual plane".

Single plane intakes work better in the upper RPM range. Dual plane intakes are better at low RPMs and for economy. "Mild performance cam" and single plane would not be a good combination. The Performer RPM mentioned is a dual plane intake.

Performance is a matter of the "package" working well together. Most likely, '78 350 heads are smog-era 882's or something similar - not at all performance pieces. Until those heads are replaced with something better, not much else you do will have much effect. Ditto with exhaust if it is still stock.
