There's lots of unleaded race gas, not illegal to add it, and it gives a lot
bigger octane boost than the math says it would. Someone told me why once, but
I forget.
That said, I'd go for displacement and low compression--cheapest way to power.
Higher compression stresses everything. Keep it simple, a mild cam so all your
gas doesn't go out the exhaust, big pistons, and blueprint everything and
you'll have a great motor. Definitely get the crank nitrided. I'll probably
use Mikuni Solex carbs because I have a set.
All you really need to do for the ports is match everything up and clean off
the really rough spots. Don't get carried away, unless you have a flow bench
and know how to use it to gain flow, you WON'T improve anything.
I have a TR3 "kit" in my shop that I need to build. I'll be doing it exactly
that way. Nice chesty motor, good electrics, quaife rear end (I've already got
one), and a blueprinted stock gearbox with overdrive (have that too). Do all
the suspension mods to make it handle, good brakes, and bob's yer uncle.
