Hey
Ok im starting the process of rebuilding the 390 in my 67 Mustang, its the original engine in the car thats backed with a C6 and a 9" Traction Lok rearend, so my question is im going to rebuild it with a little more power than stock, the rearend is getting rebuilt and so is the tranny except its getting a shift kit and rebuilt with more clutches. on to the motor, im going to get standard machine work done(Bored, Decked, Align Honed) with the oil galleys opened up, its getting speed pro 9.91:1 forged pistons (anyone know what size chambers 390GT heads have stock) with all new bearings and rings, oil baffle with high volume pump, my questions are for the top end of the motor. I am going to get hardended valve seats put in and i wanted to get the heads mildly ported and the chambers cleaned up (anyone know where this can be done at?) my goal is 10.2-10.5:1 compression, im ditching the factory intake for a edelbrock performer w/ BG Road Demon jr. 725 carb and i was looking at either the stock cam 390GT cam, the edelbrock performer cam (194/204 .460"/.480") or the Crane Power max cam for 2k-5kRPM (216/228 .533"/.563"), so thats the motor im looking at building im hoping for between 320-350HP at the crank, so i believe this will be a fairly stout motor for being a crusier and my questions are if this is a reasonable HP range, which cam might work the best, and where i can get my heads ported, and also if the hooker headers flow good and if i have to cut out the bottum of my inner fender to pu them on, thanks for any info and sorry for the long post
