Thanks for the reply. Edelbrock recommends either the performer plus cam (for torque) or the torquer plus cam (high rpms). I haven't decided which way to go yet.....although it looks like a dual plane intake? Please correct me if I'm wrong. I was looking at 500 cfm carburetors with Edelbrock's progressive linkage. That's still a bunch of cfm's for a little 302, but I can't resist the dual quad idea. As for heads, I didn't think there was a specific factory head for either 2 barrel or 4 barrel carbs (like Cleveland heads are specific to 2 & 4 barrel). Do you mean an aftermarket head that flows better? The engine I'm considering is out of a 1982 Mustang GT. Factory 2 barrel with a "marine" grind cam (that's how the GT was in '82). I was going to stick with the stock crank, rods (coditioning as necessary for high perf), heads, forged or similar pistons (around 9:1 compression) good ignition, roller rockers, and a timing gear drive. Job one on this engine will be building for dependability, the 2nd consideration will be power, and third will be the look (thus the dual quads). The one limitation I'm putting on myself is to use as many stock parts that I think won't compromise the dependability or power too much, mostly due to cost considerations. I'm trading better heads and forged crank/rods for better pistons, more carbs, and a gear drive. I guess I can upgrade things later, but I'm excited about the plans thus far.
