Edelbrock Performer Pkg

Months ago, my Son and I determined my '85 RC 360 block was overly tired. We bought an Edelbrock Performer Pkg from PartsAmerica web-site (SummitRacing is cheaper!), inc cam, intake, HD valve springs, timing set and a newly reman shorty was purchased on which we soon commenced construction.

NOTE: I had my ol' heads inspected, however, both were cracked. I ordered new ones from the same large SoCal reman which came back unworkable with the new HD springs. (Beware: RC heads have "rotator valves"). It took some time to obtain new rotator heads with the HD springs installed. The new roller timing chain is one King Kong couldn't bend. I have a rebuilt, stock Quadrajet on the new intake.

However, I'm not that pleased with end results. Performance is a whole package from stem to stern. The cam has 3 settings, I feel we mistakenly set the mid one. Likely, should have selected lower rpm torque one(?) and, someday later not sooner, may take all that frontal stuff off, again, to re-set.

With BFG 33s' and stock rear-end, Big Blu wants to get up and go at about 70+mph which is cause for several short-comings: Ain't no way this ol' stagecoach has the suspension, brakes, etc.. to safely match that speed in heavy SoCal Fwy traffic. Secondly, an ol' RC above 75-80mph is much like pushing a barn door. Let's face it, the aerodynamics are like a big ol' 747 trying to stay at 400mph in a 300mph headwind. Lastly, because of heavier lead-foot action, mpg is down significantly.

So, dot yur Ayes' and cross yur tees' on this rebuild jazz.....
Not bad overall costs though. I still have an MSD 6-A ign box standing by, along with some Hedmans (illegal in CA). I need to find matching MSD distributor to finalize that end, along with my current problem of replacing shorted out wiring from alternator to coil/distrib.

I'd like to hear from others who've done an Edelbrock. Performer Pkg rebuild on a 318 or 360. Frankly, I'd go with a slightly wilder cam and a LOW rear-end. Hey, the stock 360 is a bullet-proof, hi-torque, lo-rev deal. Not unlike an old over-size (bore vs. stroke) VW engine out of the distant past.

in 79, a stock 360 was 8.7 - 1 and .410 lift....just for reference purposes.
Ive used those cams before for stock rebuilds..they seems to be close to stock. They have the Performer Plus now thats a "set up".
Just would like to share my thoughts:

1st - Edelbrock performer package IS for lower end build ups and will do fine for a big RC. You can't expect a 400hp motor from just an intake and cam swap. The stock Hp in these '80's motors is pathetic. They have restrictive exhausts, low compression, emissions crap, etc. If you do a complete rebuild, bump up the compression to 8.5 - 9.0, free up the exhaust, and use the performer package, you'll have a pretty powerful motor. Granted, the performer package is not the most agressive package out there, but it definitley works if built right. Anything over 9.0 compression might require the use of premium gas. It's not necessary.

2nd - Hughes cams are no better than any other brand cam. You can still stay with Edelbrock, if you want, and just pick a different grind. I personally like Comp cams. It's not the brand, it's the specs that matters.

3rd - There is no reason to go with timing gears as compared with a chain. A nice true roller is all that's needed for a daily driver/occasional off-roader. You don't need that degree of accuracy unless you are racing or competing. Not to mention, they tend to be noisier and more expensive.

Don't worry about what brand it is, worry about the #'s. make sure the motor, intake, carb, cam, exhaust are apprpriate for what you want to do with the vehicle. Low end, mid range, high RPM.

My point is that it's not a bad package. You just have to do your research. ;)

just a little on the 4bbl intake,the factory 360 4 bb intake is better than the edelbrock performer i have tried both and my factory beats my edelbrock by far but i shaved the factor out a lil and shaved my exhaust ports a lil and my old 75 would scream ,and for people who just want a lilttle bit more power with out the money just get your factory intake and heads dipped and cleaned and have someone who knows what there doing shave out the exhaust ports and the increase in power would really shock you and it cost very litle to do .
