Again, careful analysis of how and where you will be driving will help in proper powertrain selection. The tires on your roller will be selected by the dealer. The factory provides no tires so request what you want and pay the difference to the dealer to bridge the gap from what they "give" you to what you really need. |

thanks - what size is typical for a 289 slab? I am a big believer in spending more money for good tires vs. garbage ones. |
You mentioned running EFI. If tuned properly, you won't have many issues with that engine bucking at low RPM's on the highway. I have a .54 OD with a nasty cam and EFI and on the highway at 70 mph pulling about 1900 RPM's, it run like a dream.

MKIV does have a valid point on the tall 5th gear on the TKO. The T5 is at its limit, torque wise with the above engine. Although it is stronger, I wish the TKO shifted as smooth as the T5, but I understand they get better after about 2k miles. |

This is of course, all dependent on engine location, body and interior panel placement, etc, as compared to an original car. It's also dependent on your requirements of how accurate you want it to replicate. My 289 isn't an SPF, it's a HiTech/Sagebrush, so I can't really advise on all of those aspects of SPF. Just saying it's something you might want to look at before you get going on the car. Larry |

And I would put the Avons as equal or better to any choice SascoSports Inc is a full-function racecar preparation restoration shop Rally-CR6ZZ-DOT&tire_size=205/70R15 96V&std_rim=&rim_diameter=15 Note these are not cheap, but why spend thousands on "horsepower" and balk at hundreds to allow it to be used? |

So about $400 each for the Michelins...still cheaper than what I pay for tires on my other cars :-) |
oops!!

If you're a HP junky, don't let anyone tell you 350 HP is too much or you'll be back in 6 months asking about fitting a supercharger or turbos or nitrous.
If you're building a slab side, you obviously want a 8.9" block. I would highly recommend a 347 for the extra 45 CI. It's either a free extra 50 HP or a lot more grunt on the low end, however you balance the cam. I run 315 toyo praxis 17", and wouldn't mind a little more power than my 535 HP EFI 427 winsor has. Passing the toll both, I can slow to 50 MPH, drop it in 3rd and hit is full force and accelerate to 100at full throttle. Then in 6th, purr along at 1800 RPM at 70 or so. But no, the radio is useless if the motor is running. Again, with the slab side, you're limited on tires; it cost to play. DON'T SKIMP ON THE RUBBER! It's the most important 80 square inches you have on the car. |
