[AT] Rationale for firing orders

[Steve W.]

I know a few members of that club.... The last Hi-Po 231 I put together
got all the goodies, billet crank, rods, pistons, heads were angle
shaved and the block was bored and decked, mains bored oversized and
centers converted using splayed bolt caps, custom roller cam and
rockers, the guy is bringing it back for me to final tune the turbo
set-up. It is in a "beater style GNX clone". It does have a few
non-stock items though!!!   I'll have to get a picture of it when were
done. He's shooting for an under 7 street car, shouldn't be hard to get
in the 6s with this beast.
