Who else but Lynn,
Well, I just bought a 89-91 NA automatic motor. The
plan is to Pport it.
Basically leave the exhaust alone. Leave the
splitters or not? The archives are a bit inconclusive here. In one post Lynn
says to keep the splitters. In another he says the Pport is very sensitive to
exhaust back pressure. I have some turbo housings I can take the insert out of
and put into the NA housings if need be.
Other info I have says the exhaust should be ported
to Close 55 deg ATDC vs 48 ATDC for stock while leaving the exhaust opening
alone.
Intake timing:
IO 80 deg BTDC
IC 60 deg ABDC
13 in intake length?
31 in length header primaries 1 7/8-2 in
dia
3 in collector into muffler
2 in dia after muffler.
7500 max power
5500-6500 cruise power running LOP.
2.17 drive and a 68 in prop.
Speed-fast hopefully.
If it sounds like this I won't be
upset:
Who says they won't Idle? That is music to my
ears!! Sewing machine be damned! A proper sound should cause
spontaneous incontinence amongst the granolas.
