SOLD OUT - and discontinued

We have recently acquired the last remaining stock of the Edelbrock 4730 Street/Strip Camshafts for the Honda / Acura B16/B18c B Series VTEC Engines.

This large purchase means one great thing for you. A Great Product at an even better Price !!!!

The Edelbrock 4730 camshafts are a hidden gem when it comes to camshafts for the B Series VTEC Engines. These are a great option for mildly modified street/strip engines and also work extremelly well in turbocharged applications.

Edelbrock street/strip camshafts spin high performance for your Honda®/Acura® B-Series VTEC engine! They are ground from chilled iron and nitride-hardened for outstanding durability. When combined with an Edelbrock manifold, throttle body, and headers, these cams offer a 24-wheel horsepower increase over stock at 8,000 rpm. With the increased lift of these Street/Strip camshafts, you will be required to change your valve springs. High performance cams for your sport compact from Edelbrock offer street/strip excitement!

With a name like Edelbrock you get a real camshaft setup right out of the box including:
- Intake Camshaft
- Exhaust Camshaft
- Assembly Lube
- Installation Instructions
- Cam Card

Win-Win-Win all the way around with this great camshaft option

some impressive dyno sheets coming soon - customer just compared these again GSR Cams in a turbo engine -- 55 horsepower gain in the midrange !!!!

Thinking about getting a set can you tell me any thing about them? Are they better then skunk2 tunner stage 2 cams?

 

hard to tell you exact gains you may see with versus the Skunk2 Stage 2 camshafts, we haven't done any specific before and after testing

I'm interested to know how these stack up against a stock set of type r cams on an n/a set up. Turbo dyno sheets make me skeptical. These are definitely in my price range, but I don't want to ditch my r cams for something that isn't actually an improvement. Is there a way you could put a comparison of the lobe profiles up of your cam and the factory ones? That would definitely sell me on them, and I'm sure lots of other people too.

 

will try and put something together

hi,
i have just received my new set of edelbrock 4730's for my b20v build and upon close inspection i have noticed that the intake lobes have a gradual (progressive) opening ramp rate and a steep closing ramp rate and its the complete opposite for the exhaust lobes where the opening rate is steep and a gradual closing rate.

is this normal?, what does that say about the characteristics of the cams in terms of rpm range and power delivery etc.?

 

we are not cam doctors so i don't have a 100% answer to your question unfortunately

we like to learn what works and what doesn't through trial and error, that is the easiest way to get definitive answers.

 

Please post a graph showing the lobe shapes of the primary, secondary, and vtec lobes so I can see ramp speed and progression of the cam profile. Also, what is the recommended max rpm range of these cams?

 

so you are telling me you can tell all you need to know from the camshafts by just looking at a picture of them -- that is pretty far fetched.

operating range should fall in the 5500-8500 range on naturally aspirated engines

:/ if you don't have what I'm looking for, it's okay to say so. As a salesman, it seems a funny tactic to attack my prowess as an engine builder. I am looking for certain traits.
