Author Topic: Looking to brake 300 rwhp, need advice ShiftyGT ¯ Member # 3862 posted                              building a new 306 motor. Looking for 300 rwhp. Stock crank 5140 forged i beam rods ARP rod bolts Probe foged pistons (give a 9.3:1 with afr 165) Stock fuel system Cobra intake 70mm throttle body stock mass air Looking at an E cam (need to smog) I am looking at either the AFR 165, or if the motor needs it to get what i want, the 185 or twisted wedge. Would this be a good direction for the rotating assembly? Do i have any worries with clearence or compression? 1.6 or 1.7 rockers? Can any one make any better suggestions on parts?(intake will get swapped later) Can I get my 300 RWHP out of this, if not what do i need to do? -------------------- 1990 GT, Back in action Posts: 396 | From: Chico CA | Registered: Dec 2003  |  : FordPny ¯ Member # 510 posted                              Hey I got a Ecam with about 2 hours running time and less then 20 miles, $120 let me know.

Posts: 2019 | From: Boise, Idaho | Registered: Jan 2004  |  : SPECIALTY15***MM PERFORMANCE*** ¯ Member # 2978 posted                              get rid of the stock crank if you can you got decent rods but that stock crank is still weak and if you run an x cam no matter =how it is installed it will still pass smog but will have p to v clearance promblems run a forged 306 with good crank afr 165 58 cc chambers ported port the intake e cam 1.7 rockers and all the bolt ons you can get and you will be really close.but even then you can put everything on and still be slow unless you do some research and get everything dialed in its easy to put something together the hard part is to make everything work if you need help call me im in sac and always glad to help fellow mustang guys to go fast 916 613 1959 ask for sean -------------------- MM PERFORMANCE 916-993-9581 Posts: 861 | From: sacramento | Registered: Jun 2003  |  : Hungry Hippo ¯ Member # 537 posted                              that should make 300 no problem. since you are building everything from scratch, i'd get a custom cam for at least 320 smoggable hp with a better intake -------------------- 05 S4 Avant(wagon) 09 C6 H/C/I Posts: 2959 | From: east bay | Registered: Nov 2001  |  : stoauto ¯ Member # 2803 posted                              you'll be fine with the stock crank, know your limits, and as long as you have good aftermarket pistons with decent size valve reliefs, i wouldn't worry about p to v clearance with the 185s, and a SMOGGABLE cam. Posts: 1054 | Registered: May 2003  |  : ShiftyGT ¯ Member # 3862 posted                              So if the X cam will smog that is going to be my best choice for good HP. If i get the 1.7 rockers how can i ensure that i get good piston to valve clearence? Would 1.6's make the p/v clearence issue better? or is there a dished piston or piston with larget valve reliefs amend that? Good help so far, Keep more info coming please. -------------------- 1990 GT, Back in action Posts: 396 | From: Chico CA | Registered: Dec 2003  |  : stoauto ¯ Member # 2803 posted                              well, if you add 1.7s your looking at ROUGHLY .030 added to the already .542 lift x cam. heres the formula to figure out lift with the 1.7s .542 Divide by 1.6 X 1.7 = .575 i would probably stick with the 1.6s for the hell of it.

Would i be running lean on a stock fuel system with the twisted wedge or the afr 185?? What about the 165's?? -------------------- 1990 GT, Back in action Posts: 396 | From: Chico CA | Registered: Dec 2003  |  : ShiftyGT ¯ Member # 3862 posted                              oh... was waiting to buy the mass air meter until i knew if i was going need larger infectors or not. -------------------- 1990 GT, Back in action Posts: 396 | From: Chico CA | Registered: Dec 2003  |  : PurpleNotch CAFords OG Member # 2902 posted                              You wont make over 300rwhp with that combo i would go with a little more compression and a better fuel system my 331 with afr 185 heads and a bigger than e-cam cam was right in that arena untill i put the blower on. just pm for my motor details or call me to talk about it. -------------------- **The creator of the infamous purplenotch** http://www.mustang50magazine.com/featuredvehicles/m5lp_0508_1988_ford_mustang_lx/index.html Posts: 3177 | From: Bay area | Registered: Jun 2003  |  : svt1165 ¯ Member # 2722 posted                              a blow-job will help ...blower -------------------- HK MP5K HK G3/MSG90 HK P7M8 HK USPc 9mm HK USPc 40 SW HK USPc 45 ACP HK/Benelli M1 S90 FN FAL SIG Sauer P229 Posts: 495 | From: Stockton | Registered: Apr 2003  |  : Krz88lx ¯ Member # 4261 posted                                 get some pimp juice -------------------- Krz4rd5 Posts: 1286 | From: san jOse | Registered: Mar 2004  |  : street_illegal_stang ¯ Member # 1554 posted                              just buy a cheap stock shortblock ,put on your top end goodies ,and strap on the "pimp juice"for you car.say 100shot off the line? thats sounds kinda fun.. with the juice you'll be "close" to 400 rwhp think about the big savings too Posts: 1276 | From: Long Beach C.A | Registered: Jul 2002  |  : 166 Merlo FELONY MOTORSPORTS Member # 1549 posted                              boost the bitch and get an rpm 2 -------------------- '89 - Boss Coupe '70 - Drop Cutthang '68 - Cougnut '87 - 0166, Its real Posts: 3954 | From: Thebay | Registered: Jul 2002  |  :
