edelbrock power package
Thinking about rebuilding the engine this winter so I'm starting to shop around for prices and parts. I've looked a little at the Edelbrock performer power package deal but wanted to know if anyone has installed it and how it did, what kind of power it made all that good stuff. Anyone done this? Does the performer..not rpm just normal performer fit under the stock hood? I thought it might fit with a drop base and a milled choke horn, but I assume someone already knows the answer to this one.
Thanks,
Steven

When I first started building my engine I sent Edelbrock an Email with my gas octane problems here and the high temps we have also. They came back with a package suggestion plus recommendations on pistons to use. I ordered all the parts they suggested from Summit including the 64cc heads and pistons, rods and rockers. I sometimes have a dieseling problem when the engine is hot as the fuel here is not regulated. With any stock 81 Corvette any thing you do improves performance. I am running the summit high output distributor and dynomax headers. I did have to install a plate under the carb due to high engine temps plus a fuel gage and flow regulator due to the Holley high output fuel pump. In the future I may install a slightly bigger cam but not right now. I’m guessing about 350 HP as it is now. So from 190 to 350 it is a big improvement. You should be able to complete the engine for under $2,000, the heads being the biggest cost in this.
You will need a dropped base air cleaner but there are many available including Edelbrock. I modified one myself.

Regardless which heads you end up with ... I suggest you'll get a better intake-head-cam match for your BBC & your needs if you investigate & buy separately ... the combos are great for a few folks ... but combos are really a compromise for most others ... maybe a decent compromise, but still a compromise.
We do have for sale a New pair of GMPP BowTie alum BBC rectangle port 118cc heads ... supposedly made by EB just as their BBC rpm. Email if serious. Much more info at this link:
