Just completed a 3.5 year rebuild of my 97gt. Got it dyno tuned and am putting out just under 300hp and just over 300ft lbs. I found out I have a problem....my current MAC CAI and stock T/B setup is restricting air flow which is restricting hp. So what options are out there top help...

Hey all, need a little help on choosing a new fuel injector size. I have a .020 bore with 9cc pistons and Stage II port and Polished PI heads. I also have a MAC CAI and a 90mm MAF. I am staying N/A, no power adders. I was thinking 24# what do you all think?

I just cracked my 97GT romeo block and am looking at new/used ones. I understand that all romeo blocks are interchangable but my question is specifically is there any major performance differences when swapping out a 96-98 romeo block as compared to a 2003 Cobra Romeo block? I understand...

Engine block is ready for p/u and I am about to embark on a complete rebuild. I know after the rebuild I will need a custom tune but I am not sure if a simple tuner like the Diablo Predator or SCT X2/X3 to change the stock computer is what I can get away with or if I need to go to a speed shop...

Machine shop just called and my GT crank is too badly scarred to machine so I need another one. I am looking into the cobra cranks but everyone seems to say that slight modification will need to be made to 96-98 blocks for proper fit. Anyone know what modifications need to be made? I am...

Hello All - I have had successful day breaking down the 97 GT block for machining and rebuilding but I have come to a road block and need a little help. I have the pistons out and all the Main Bearing Cap screws removed (side and top, 4 per cap) however it seems the caps are "pressed" into the...

I have a 97 GT with Ported and Polished Multi-angle Valve Job PI Heads and Cushman Motorsport (Jim's) Stage 2.5 Cams & Springs During this rebuild I am looking at staying N/A and raising my CR to about 10.5:1. I am sticking with the Steel Crank, have read I should upgrade the stock...

I have a 97 GT naturally aspriated with PI Heads and I am planning putting in flat top head pistons with no relief valves inlets. I am trying to decided between Comp Cams XE268H (part # 102200) or XE270AH (part #102600). The major difference between these two cams are the valve lift. The...

Hey guys I am looking for a Good Machine Shop in the Tampa Bay area or central Florida area which I can get some good service and help at on my engine rebuild. I know the technical aspects of some things but need some assistance in preforming some of the actual tasks. Thanks!

Any help would be appreciated - Here's where I sit. 2.5 years ago 97GT went down with bad main engine bearing. Had minor power adders (U/D pullies, T/A, Mac Pro Chamber, Flowmaster Cat Back). I purchased PI Heads & BBK Short Tube Headers & .020 Flat Top (non-nothced) CP Pistons for the...

I am going to be running a N/A 97 GT with a PI head swap and new forged internals. I wanted to use flat top pistons and was wondering if anyone knew if I needed valve reliefs on them or not.

ok, need some clairfications on the actual difference between stage I & stage II. (i.e diffs between duration, opp range, etc) Some suggestions on brands and types would be great. I will be looking for daily drivability and longevitity.

Ok guys, will a 2003 Cobra Engine fit into a 97 gt with a simple engine swap? Will the trany match up, fuel lines, etc? Has anyone does this and what mods need to be made?

Ok guys as I rebuild the block I need to decide if I will go with a future blown application or stay N/A. I most likely will be rebuilding with the Stroker kit. Please give me your reasoning.

Need some advice.... Ok long story short..... Had knocking sound in 97 4.6L SOHC Thought it was valves, rocker arms, cams, etc (something top end) Performed a PI head swap for ****nit and giggles:rlaugh: Didn't fix knocking sound:mad: Now have entire motor pulled out of car...

Ok just completed the PI head swap hoping to fix my knocking (more of a clang) sound. When the engine is running it sounds like a steady clang clang clang. Then only other thing I can think of seeing that I rebuilt the entire upper part of the engine is that I have a bad crank bearing. Anyone...

Hey guys - almost wrapped up with the head swap and am installing the oil dip stick tube. I put on BBK headers. Where the hell is there room to insert the tube back down the side of the engine and into the spout?:SNSign:

Ok following the Ford manual and here are the steps (word for word) and then later my question. 1. Tighten head bolts in sequence to 28-31ft lbs 2. Rotate head bolts in sequence 85-95 degrees 3. Loosen head bolts a minimum of one full turn (360 degrees) 4. Retighten head bolts in...

Hey need some advice. I am putting in the new heads (PI) and am to the timing chain install. I marked the chains and all and installed them easy. I went ahead and rotated the crank shaft with the chains tight to turn the cams and the pistions to see if any valve tapping or lock up would...

Ok just about to finish up the PI head swap and I am installing my BBK adj. Fuel pressure reg. I have a liquid filled gauge and where the outlet is on the reg leaves no room for the gauge because it is right next to the bolt for the fuel rail. Any one know how to solve this? A 90 degree piece...
