RE: Changing to Edlebrock heads and Intake??

I'm running Edelbrock heads and Perf. RPM intake on my 428-SCJ. Edelbrock CNC's the intake to match with the medium riser port dimensions of their heads....w/just a tad of gasket matching was all that was needed.

What you have now may not be good at all if the CJ intake manifold ports extend below the bottom of the ports in your GT heads. You never want the intake ports to be larger than the head ports.

Also, Edelbrock makes (2) FE heads, one with 76 cc chambers and larger 427 valves which you don't want unless you want to lose compression and have to notch the block big time to unshroud the 2.19" intake valves. The other head uses 72 cc heads, smaller CJ sized valves and 16 bolt CJ exhaust ports. Both have medium riser intake port dimensions.

This thread, so far...
