Anybody ever heard of a Edelbrock Performer EPS? Well I hadnt until today haha. Story here is I just bought a 74 1/2 ton Chevy to haul my car parts arround and go dirtbiking . And it had a Olds 350 in it ...yeah. Well needless to say im close on the engine already, I have a set of 993s laying arround and I have just pulled a 4 bolt 350 from the junkyard for it. I will build a better shortblock for it soon but ive got 3 cars going right now .

Anyway heres the combo...

Edelbrock Performer EPS Manifold
Edelbrock carb (unknown series) 600cfm vacuum secondary
Unknown brand 1 5/8 x 2.5 Longtubers with turndowns (junkyard find )
This Cam
.420 (at 1.5) intake 204 @ 050
.442 (at 1.5) exhaust 214 @ 050
112 LSA
Hydraulic Flat Tappet
A set of 1.6 ratio rockers from Speedway
A stock pan with 2 crank scrapers and a windage tray
And a set of P&P and gasket matched 993s milled to 70cc
Stock 4 bolt shortblock.


Im hoping to make 325 horsepower and 425 torque. And eventually switch it over to E85.

 

the EPS is just a level above the regular performer and right under the rpm's and airgap's.. its a decent manifold for the price.. i had one on my first 383 and it was good.. made 316rwhp and 359rwtq.. with a 650 edelbrock carb.. its mainly a midrange manifold.. after 5700, it hit a wall.. should be good for your app..

btw, its edelbrock.. not edylbrock..

 

fixed lol

 

About the only good things I see in that combo are the 350 shortblock and the intake manifold. Possibly the headers, if they fit a 3rd gen chassis (many don't).

Heads - junk.
Cam - lame.
Rockers - unnecessary.
Carb - show, not go.
Scrapers - unnecessary.

Spend your money where it makes a difference. Heads are key, 993's are slugs. Not sure what cam that really is, but you can do better with a more modern grind. Most cams are designed for 1.5:1 rockers, so if you pick the right cam, you don't have to crutch it with 1.6 rockers. Scrapers are a tweak for the nth bit of power (although they won't hurt anything).

 

actually the cam is similar to they "dyno matched" camshaft that edelbrock sells, by the way, lets have a more positive attitude in here five7kid

 

5.7 is just being honest.

i think a set of vortec heads with a cam to match would be a much better choice, of course it would require a new intake.
600 is a bit small on the carb. a carter AFB carb isn't the best performace carb around.

 

Ok, I am not much of an Edelbrock fan but i feel that they do their homework and research. This is a part of the "power package" they reccomend for a 350 "performer" motor

performer eps intake #2701
performer plus cam #2102 .420/.442 204/214 112 LSA
performer series carb #1406 600cfm
performer heads #60759
1 5/8" headders

This combo made 310 horse and 377 ft/lbs. F-body demon appears to be going for a very similar approach with the exception of the heads. While I am not familar with chevy head casting numbers, I think with a 1.94"/1.6" or a 2.02"/1.6" valve combination in these "993" heads, along with gasket matching and pocket porting, the result would be rather satisfying.

I do agree with the idea that the carter/afb is not a performance carb of the quality or capabillity as the 4160, 4150, or 4500 but that is also personal choice and preference, and generally I feel the edelbrock is not bad carb to use, i perfer to stay away from them due to cost, lack of parts availibilty, and frankly i don't understand how they entirely work.

 

they were just being honest jon... edelbrock seems stuck in the past with thier cams that "power package" is junk for the cost and the HP they brag about

your right about them doing their homework though only they do most of it on marketing and less on research

 

all i have left that is edelbrock is a vic. jr ported to a 1206 and a TBI strut brace.. their cams are a joke for performance.. maybe if you are looking for a 10-25hp increase over a stocker then its good

 

Like 5678ta said. The Performaer EPS is just a newer, slightly better version of the original performaer intake. I think they claimed 5hp 9ftlb over the old version.

As for the rest, well, like 5.7 said... Nothing to get all hot and horny about...


The edelbrock carbs arent great for much other than show. I still havent got the chance to tune my new holley, but i can still say that dumping that edelbrock carb was the best thing i have done for my motor!

That cam is very tame, definately not what you want if your looking to make decent power.

Heads... Heads are the big ticket item, try to find something better if you can




But you can slap it all together, it will definately run. But dont expect it to set you back in the seat when you hit the fun pedal.

 

Lets all take a step back, he isn't looking for a hot performance engine for his third-gen, it's for his truck to haul around parts. **LOW END TORQUE** desired.
So, you'll probably find most of us on this board will tend to give you advice that's more suited to your 3rd gen, and we're not in the mindset of truck type engines.

For your truck engine, that low duration cam isn't bad. It's not a modern grind, so you're leaving some power on the table, but it's a low RPM cam, what you wanted.
I'd look closely at the Compxe256, or one of their 4x4 cams in the low duration range.

2nd, those heads are pure unfiltered garbage. Also, E85 is great with higher compression. I think this is one of those perfect cases to use 305 heads, like 416's. Dirt cheap, and with a bit of porting you can have a nice head, with a smallish port for good velocity. And, big key, no need to deck the crap out of it to get a nice CR. You can pull some timing to get it running well on premium, but then it'll really love E85 with the higher CR.


...PS - If you already have those 993 heads ready to go, I guess you might as well use them, but I would never advocate the spending of money on those heads in the first place... And I don't really think you'll hit your goal with that combo of parts as is, i'd say 260HP or so. In all reality, it's basically a stock smog 350, smog heads, tiny truck cam, etc. If the 350 made 170HP stock (which it did), then 260 is leaps and bounds above, which is what headers, good intake, and the porting of the heads and slightly better cam would give it. But not quite 325HP and 425tq

 

Well thanks for some of the feedback guys. This is what I was looking for, basically was just a tidbit of yes/no on the EPS.

P.S. The 993s and 882s (identical but thinner) are supposed to be the best of the smoggers according to linginfelter. I got the 993s for free so . All and all this engine is going together for $500 so im happy if it runs lmao. again thanks guys.

 

Wow. There's so many points made in this post that I can totally agree with. Five7, while maybe sounding kinda harsh, actually hit the nail on the head with everything he said. Spitot totally nailed it with his summary of Edelcrock. Lots of marketing and "bling" with very little performance gain. And all of Sonix's advice totally makes sense if you're simply building a truck motor on a budget. Not all, but most of Edelcrock's stuff is best suited for some 70 year old guy who just wants his 283 powered, air conditioned, streetrod to look fast, but be reliable.

 

lol I agree completly with the Edelbrock statements in this thread. IMO they're Heads and Carbs are JUNK and only some of thier manifolds are worth anything (EX: Victor JR) and even then.
