[QUOTE="Mr. OAM, post: 217660, member: 9816"] I caught heck for this engine once already but as stipulated it was built for my wife who wanted a "nice idle", which greatly limits the power I could have made with it. She wanted something that would idle nice (no lope or anxiety), be reliable, and be fun when she wanted to have fun (read "spirited driving"). So with all this in mind I tried to make the torquiest "mild" engine I could without spending huge bucks, though I did spend plenty. It is in a 2,700 pound 1966 Mustang, could even be less. I need to get it weighed, and an inaccurate weight told to the dyno guy may have also skewed the output numbers, I don't know. Anyways she told me she doesn't want me to make it any faster (I asked) and she is very happy with it. The only reason it is a stroker is because we were told it was a 302 when we bought it but it turned out to be a 289. Rare circumstances at Ford behind that confusion (casting numbers, and we knew it was not the original engine) She said she would rather it be a 302 so while looking up reciprocating assemblies for it I found the 331 stroker kit was the same price. This was a no brainer so I got it. For long term reliability I did not get the 347 kit. It accelerates from 60 mph to 110 mph the same as it accelerates from 0 to 60. Throttle response is amazing too. I didn't make it to the track this year to see what it will do but it was on a dynojet last year. I suspect, looking at the dyno sheet, that max torque could actually be a little higher below where WOT occurred. Here's the build.... 1968 302 Block Ford Racing GT-40 X305 Aluminum Cylinder Heads (out of the box) Harland Sharp Aluminum Roller Rockers Smith Brothers Custom Pushrods KB Forged Aluminum Pistons (full float wrist pins) File Fit Moly Piston Rings Eagle 3.250" Stroker Crankshaft Eagle 5.400" I-Beam Rods Clevite Bearings Lunati Retro-Fit Roller Camshaft .522" Lift, 268* & 279* Adv. Dur. (215*, 224* @ .050") Lunati Roller Lifters Edelbrock Performer RPM Intake Manifold (out of the box) Barry Grant 625 CFM Road Demon Carburetor (out of the box) Doug Thorley Tri-Y Headers Ceramic Coated Ford Racing Underdrive Aluminum Pulleys (They are aluminum and "pretty") Dyno sheet is below, along with a pic of the engine. I designed and machined some custom parts for it, of course. The engine went lean at the moment of WOT so I need to adjust the accelerator pump for a slightly heavier squirt.
