360 build recommendations

I like this set up but notice how much work was done to the heads. They flow 260 cfm and are the 2.02 heads. It makes a lot of since far as "bottle necking" the flow. As mentioned previously above a motor will not much if it can't breath.

360 rebuilt with 10:1 compression flat top cast pistons, original crank turned .010"/.010", rebuilt factory rods. Factory windage tray installed. 2.02" heads with competition valve job and ported to flow 260 cfm. Edelbrock RPM intake, port/gasket matched. Holley H.P. 750 (.076" front, .080" rear jets). Large 1 3/4" primary tube headers. Comp Cams 305AH-8 camshaft with .525"/.540" lift and 305/312 degree advertised duration, 253/260 degrees @ .050", 110 lsa, installed at 108 intake centerline. This motor is a brute for a street car and would only be considered a weekend blaster.

That's a pretty big porting job for stock iron heads. Just about the max. By the time you pay for porting and related work, you're almost into a set of Ede's. Plus when ported to that level they are very prone to cracking. Ede's won't flow 260 OOTB, but have the potential for 300cfm at .600-.650 in the right hands. So later growth is a possibility if so desired.

That camshaft is VERY aggressive. Needs a lot of convertor and an idle likely over 1K.
