Hello,

I have a 66 daily driver w/ 289 with an Edelbrock performer intake & Edelbrock 600 cfm carb. The car also has dual exhaust. I am considering putting factory style HiPo exhaust manifolds and cylinder heads from Powerheads on the car (see www.powerheads.com).

It was suggested to me that a new camshaft may be in order for added performance. I figured the Edelbrock Performer cam might be a good idea since I have the Performer intake. However, the Performer RPM cam looks like it might even give better results.

My question is would it be a bad idea to use the Performer RPM cam with the Performer intake? Does anyone have any ohter good recommendations? You'll have to keep it simple, I'm pretty ignorant in this area of conversation.

Thanks a lot for your time,
John Thomas

With your current set up I would stay with the Performer Cam.
If you want to upgrade the exhaust side, get a set of Tri"Y" headers or a set of shorties.The upgrade to "HiPo" manifolds is of limited benefit. Yes they flow better than stock manifolds but they are not that good to justifiy the expense. After all they were the first thing Shelby threw away.I have run all three types on my K code and you will be much happier with the TriY's JMHO

IMO, I'd go with the Performer or SVO A311 grind and a set of shorties like the JBA's that Johnpro and I run....we've had outstanding service (for me nearly 8 years now) and they run as quiet as stockers with no PS interference...

You didn't talk about the rest of the drivetrain....if C4, I'd recommend a shift kit and 11" 2000-2500 stall converter and external fluid cooler...

Eventually, a 3.25-3.50 rear gear would be the best compromise between economy and performance...

Good luck!

I have the JBA shorties and I highly recommend them. They don't seem to have any of the problems associated with full length headers (like ground clearance, fit, etc). Also, they are pretty easy to install.

IIRC, Johnpro used the 66 engine mounts which raise the engine a little and give more clearance...I used the stock 64 mounts so it's a little tight by the steering box and passenger side shock tower bulge....but it does allow me to run a 1/2" carb spacer under my 4100 on top of a Cobra manifold, use the stock air cleaner housing and still clear the hood..

Jacked the engine up a bit and slid them in from above...no major difficulties that I can recall but that was over 7 years ago.
