I was just wondering if anyone has tried one those top end kits by edelbrock. And if so, wich one did you use and did you get the hp gains that edelbrock is saying. 367 hp and around 340 ft pds.
How do you figure? Thats like buying a $5000 400+ hp crate motor and putting too big of a carb on it and then complaining that you cant get anywhere near the advertised performance. It is an advertised rating, at the flywheel, it is very easy to get the numbers they posted using the components they give you with a fresh bottom end. But if you have a weak bottom end or a bad tune on the carb of course you wont get the numbers, but it is also possible to get better numbers then what they show too.
i used a perfomer rpm heads intake cam kit on a chevy 350. it had a 700 cfm holley on it. it ran really good. dont know the power numbers but was a strong running motor. ive used the performer rpm heads and intake on a ford 351, it had the ford f303 cam and a 750 holley, and that ran really really good. beter than than the chevy did.
Please....by all means......just where exactly did you "herd" this information? I simply love internet gossip/heresay/rumors. And for the OP....they're pretty close to the test numbers. We've used a couple of them and had them all come within 5 hp of the advertised numbers. Then we swapped out that pile of dogsh!t Edelbrock carburetor with a good Barry Grant Demon carb and picked up 15 hp every time.

350 hp maybe. Edelbrock claimed 387 hp..... edelbrock is saying. 367 hp and around 340 ft pds... hmmm the numbers dont match http://www.summitracing.com/parts/EDL-2091/ so Edelbrock is advertising 367 Hp on summit and he is saying 350 Hp can be done, why not 367 Hp, whats wrong here? More importantly where did the 387 Hp that he is talking about come from?... You can loose 10+ HP with the same tune at different altitudes, you have to remember they calculate those numbers at sea level. So if you build a 367 Hp setup at sea level and drive it up to the Bonneville Salt flats or the area where I am at then your 367 Hp motor suddenly turns into a 350 Hp motor due to the air density(4218 feet above sea level), everything starts to flood out.(thats also the reason they started using the Dry lake beds in california for speed runs they can get more performance out of their motors then up here) for reference he is in York Pa, where he is located and the elevation is 480 ft above sea level.
Yeah, that was my post. For the roller cam top end kit I had Edelbrock claimed 385 hp, not 367. If you look at the Edelbrock list of equipment on their test engine they're running 1 3/4" primaries headers, not what most guys with "street" 302s run. The heads are ok, not as good as AFR, Trick Flow, Canfield, etc., but better than stock at a decent price. I still run mine. The RPM intake is a good piece. The real POS in the combination was the "Rolling Thunder" roller cam. Very lazy lobe ramps, almost like they were developed from old hydraulic flat tappet profiles. I'd suggest getting the heads and intake, then get a modern cam design like a Voodoo or Comp. I replaced the Edelbrock cam with a Comp XE266HR, made a world of difference. Shadow's right about their carbs, too. A reporter asked Vic Edelbrock why he runs Holley carbs on his road racer instead of his own carbs. His answer, "Holleys make more power".
Hi bmcdaniel, I'm another passioned maverick owner. Living in Brazil, running 1974 Maverick, Stock V8 302 I'm just looking for some directions on getting extra power from the old 302. In my country the companies that sold top end kits, ask a huge amount of money for a simple kit, and give not much help on installation. I'm looking to buy the part in your country that gets here whit taxes, at a lower price than buying directly from people here. So, if you can give me exactly the list of parts you used on your engine or suggestions based on your experience, I'll appreciate a lot for the help. I'll be glad to get something near 350 or 380 HP. Tks a lot, Best Rgds, JV
I have heard of many edelbrock headed 302 fox stangs that went mid 7's in th 1/8. They are a very nice set of heads
Thanx for all the input on the edelbrock topend kits. I was impressed with the price of the kits. I have never used one, but when I start building the motor I'll prob. go with one. I'm also looking into the stroker kits, sence my car is also my daily driver. I can look up parts and kits all day long, but its the addvice and experience of the guys who have tried them that will help me decide.
