Is it worth it to install the Eddy Base, and Runners on a fairly mild 350 TPI.???.It is in a 92 Z28, the car has headman headers, dual cats (minus the cats) 323 Posi, AFPR and runs in the hi 13's... Would there be any gain??? Pro's???? Con's??? Will be tweaking the fuel delivery system here shortly, and am kinda thinking as long as I have to have it apart anyway, might as well go for it...They are high dollar.......Thanks for any input on this subject guys..I know some of you out the have to have experience with them, Thanks, Tom

BTW, going with eddy, cuz summit sells them, and I have a summit card..Unless someone know something better they sell...lol

Personally if your keeping the long tube style I would get a FIRST intake. The edelbrock is ok just it has kind of small ports and would need porting in the long run if you start upgrading the engine.

Steathram might be a good option to if your into that.

yea trust me get a FIRST.... the FIRST flows better than a out the box superram... i went through all the ported edelbrock/slp and ported plenum airfoil you named it stuff... the ports on the edelbrock base are BARELY bigger than the stocker and the slp runners are only slighty better than stock runners out the box...dont be fooled by the 20 horsepower gain on a stock engine that those slp runners say they provide.. you have to hog out those slp runners to really see any gains... if you dont know what your doing you can mess up the 2nd and 3rd harmonic tuned effect of the runners by just going porting crazy.. really wasnt satisfied with all the time and effort i put into it.... dont get me wrong there is a power increase but for the money your FAR better off with the first intake.... it BLOWS the doors off the normal ported aftermarket tpi stuff unless you seriously cut and welded the stuff like the california guys do... im bout to take off my old tpi setup off sunday and put the FIRST on monday.... id say the FIRST is as good as it gets as far as out the box tpi setup goes...

88, i have been following your buildup. ..As I said I have a summit card with enough on it to get the eddy base, and runners..Is there any gain, over stock?? If not I will just leave it alone..Am thinking of selling my 92 to sink more money in my 89..Thanks for the advice......I know i can not afford a first intake, altho yours does look killer...Anyone else want to chime in?????

yes there are gains and you will notice it but the for the money its not worth it and you can get a MUCH better intake for the price they are asking for there edelbrock base and runners..... if you set a stock base and a edelbrock base side by side and look at the ports you will be shocked to tell which one is really high performance..... the aftermarket base just has more meat for you to port and open it up...you really got to port the stock plenum edelbrock runners and edelbrock base to really see an improvement and thats with the aftermarket stuff... i think you will be dissapointed by it unless you really port them and even then its not worth the time to port it imo.... the vortec tpi base is supposedly even worse than the factory base...... which is quite sad..... then they wanna know why alot of people ditch their tpi's for hsrs mini rams or go carb.....

on a side note if you can manage to find a original accel superram base and as&m runners those would be quite abit better than edelbrock stuff but neither are sold at summit so it kinda kills that idea

yeah right now with money the way it is, i can only use the old summit card..lol...

Think they just send you a Edelbrock one in the box now, but yeah if you can get your hands on a accel one your better off.

Just my 2 cents...unless you want the stuff tomorrow, check classifieds on here and your local craigs list every day...I picked up a complete tpi intake with an edelbrock base for 200 plus a set of slp runners for 275 off my local craigs list(tip, also pays to check any craigs list within a reasonable drive of your area). I later sold the eddy base when I foun an accel base, matched the runners to the superram gaskets and siamesed the plenum and am very happy with the difference(on a low budget) on my 87.

The AS&M tube runners are great. TPIS sells them as their "Large Tube Runners". They are also the most pricey of any of the stock replacement style runners(about $450) and Summit doesn't sell them. The early ACCEL Superram base does work well but I ported mine huge for maximum air flow. It's really not hard to port the base. You just need a long mandrel for your die grinder and a set of porting rolls and alot of patience. Unless you go with the First, you'll have to port the stock plenum no matter what brand of base and runners you go with. No one makes an aftermarket plenum. They all expect you to use the stock piece. It is easy to port, again using the long mandrel in your die grinder. TPIS provides instructions for porting the plenum. I of course radiused mine around the runner outlets for maximum flow.

As far as what type of gains you might expect, that depends on what you do with the engine. Remember, a well built engine is a system of combined parts, matched and fit together for maximum benefit and it always starts with a properly machined, balanced and clearanced bottom end. Bolting on an intake will make marginal difference on a stock motor. The OE heads and cam run out of wind at about the same point as the stock intake did. I would buy the parts and use them if you like, just don't expect too much until you take the time and spend the money to build a motor that makes use of the parts.
