People with afr's 165's please come in

I went low 13's on mine with a 4 spd and a 3.00 gear on a 225 street tire. I was also shifting more than 500rpm early and running too lean on the top end, it was flattening out over 5,500. Now that it's tuned right(it pulls hard all the way to 6,500) my 2nd gear synchros are taking a crap. I swear it's always something. The intake is the Weiand 8124 and the cam is Crane 2031.
165's are more than capable of supporting more power than most street 302's make. I've seen a few people with well built setups running unmodifed 165's on 302's go mid-high 11's in street cars, with tires and suspension of course. Flow volume is only a small part of making power, that's why the Formula 1 designers opt for very small ports, sacrafice flow quantity for flow quality. You need to mix the fuel and air effectively before it gets into the chamber, and then burn it rapidly and completely. Port velocity has a bigger effect on power than port flow does.

For the rebuild kit, are you planning on using your rods and crank? If so, then you cant really order a rebuild kit till your engine is apart. You wont know how much of an over bore you need or if the crank needs to be turned.

Definetly get the 185's, and a can of playdoe from the kid's play pen to notch. Dont add cost to your project buying new ones, it wont even increase your power.
Betcha cant wipe the grin off of your face when your done : ) .
And screw the notching tool, use 1.5 in etc abrasive on a angle grinder or drill. It cuts smooth, even and fast, wear safety goggles, nose and ear protection. This gets messy
or your other pistons will look about $250-300 parts, $100 balanced to old piston's weight, $80 Pressed onto rods.
