Hey Greg:
Just a couple of thoughts based on my 1 year experience in SPF642.

15 inch tires (which I have - 245 front 275 rear) are getting harder and harder to find. BF Goodrich and I'm not sure who else. If I were doing it again I might go 16 or 17.

As far a engines go I can tell you this. Street performance is all about mid range torque, 2,500 RPM to 4,500 RPM. Torque is what accelerates the machine. Mid range torque loves dual plane manifolds and carburators which are not too big. Single plane manifolds are designed to be at there best a high RPMs. If you get a Holley which is too big for the RPMs and cubes you have there will be poor flow through it. Your low end performance will suffer at the expense of the high end you never or rarely use. The other disadvantage of the killer show engine is the price you will pay in low mileage. I have a 351W, dual plane with a 650. It's the fastest car I've ever driven (and I had a few).

You should do what makes you happy. When you do get your SPF be careful, The low weight, high power and short wheelbase can be lethal.

Good luck, Bob
