289 or a big block?
My mustang currently has a 289 in it and I was wondering how hard a big
block conversion would be or if I should just build the 289? thanks |

I did the same thing with myh 68 fastback--took a 289 car and put a 390 in it. If you check my website, http://www.tucsonpony.com/Trouble you'll see what I had to do. Basically, change motor mounts, put in shock tower supports, change brackets, suspension, etc. Nothing that's really difficult, of course, but you want to make a thorough change so that the car will support and handle the weight of the big block properly. For example, I went with the Edelbrock Performer RPM intake and lightened the front end quite a bit that way. I also moved the battery to the trunk to offset the heavy nose. The more you can do to lighten the load, the better off you will be in terms of handling. -------------- Laurie S. Thunder Snake #7 |

What year is yours? My mechanic said that the timing chain is getting bad on mine, and it's got almost 100,000 miles so I believe that the motor is really due for a rebuild. A racing shop in town says that they can put a stroker kit into the 289 and do a performance build for about $3900 giving me around 300 horsepower at the rear wheel. Not bad at all... But for $5900 I can get a 460 with 550 HP and 545 ft/lbs at http://www.fordracingparts.com/parts...tKeyField=6587. Of course, that means that I need to showhorn a C6 transmission in and then swap the rear for a 31-spline 9" so it's going to be really expensive by the time all is said and done. I have also thought about getting a cheap rebuilt motor from he http://www.rebuilt-auto-engines.com/...02105595755.f6 but again that would mean a C6 and a 9" rear end, so it would not be cheap. This would allow me to at least get a big block in, then I could build the engine in less expensive stages. By the way, Crites has the parts you need at http://www.critesrestoration.com/mustang.htm.

It has been suggested in some circles to do a 347 stroker kit with the
289 rather than a total swap. Just a thought.

That is an acute case of the "might-as-wells," going from an ailing timing chain (a one-day, $100 job) to a 460/C6/31 spline 9". :-) My idea for a low bux package is to start with a cheapo 302 short block with forged pistons and 9:1 CR, then add a centrifugal blower. I'd use a carb and one of these "hat" things. http://www.sd-concepts.com/Carbhathats.htm This combo would run $4500-5000, and would produce 400 rwhp -- more than enough for a '65 Mustang -- without destroying the handling like a big block will do. 180 Out |

It's what I was advised to do rather than swap for a 351. I have done
neither, so I can't say first hand. But it does seem that I have read in the kit description in one of the many catalogs (Ford Racing, Summit, Jegs, etc) that it can be done. I would be doing a lot of investigation and consulting engine shops (more than one) before making the move.

"Spike" > wrote > It has been suggested in some circles to do a 347 stroker kit with the > 289 rather than a total swap. If the 289 is a good solid builder block, I wouldn't turn it into a stroker. Good 289 blocks are impossible to find these days. Most are bored to hell, cracked, or rusted beyond belief. If you want a sleeper motor, then drop in a stroker 351W. Take it out to 427 and it'll still bolt right in. BB displacement from a SB. Or you can run a more economical stroker 351 like I did. 393 stroker- the only part that isn't bone stock is the crankshaft. You use the original 351 rods and use 302 pistons. I saved over $1k by doing it this way. -- Scott W. '66 HCS Mustang 289 '68 Ranchero 500 302 '69 Mustang Sportsroof 351W ThunderSnake #57 http://home.comcast.net/~vanguard92/ |

I can see 331, but I don't think there's enough deck to do a 347. I think the assembled height would be too tall (barely). -- Scott W.

I saved over $1k by doing it > this way. Scott, OE rods and pistons and a $220 steel stroker crank (as referenced on your web site) have definitely got my attention. I wonder if you could price list the whole deal, or at least broken down into major categories like rotating assembly, machine work, etc. Any tips on scoring a junkyard 351? 180 Out |
