The 64cc heads would help, but if I go wiht the swirl ports I still only have 67cc heads, along with the smaller intake ports to promote velocity at a low rpm. This car came with the stainless tubular 'headers' that only fit the weeny port 307 7A heads. Don't want to bother changing those two parts out just yet if I switch to the 403 shortblock.

Ewww, Regals. I'm cool. The 87/88 front end messes with people enough. Only the cholos and lowrider crowd seems to know what it is.

I think the Olds diesel just was misunderstood by the engineers and owners. Replace a few things add a proper water separator/filter system would take care of a few basic issues. It would also keep ancillary components attachment simple.

The TH2004R I mentioned is an OD unit. Only change would be to use a different trans crossmember, everything else stays the same.
GV units are neat and splitting gears is neat, however the unit is big, expensive and requires some fab work. Plus the current transmission(TH200C) uses a one piece case. No where to bolt the GV unit on, and a TH350C unit would net me a loss in first gear from 2.74 to 2.5*.
Just easier to use the TH2004R unit.

I was hoping to find a 17" AL space saver. The 98-02 F bods did have them in steel, but the offset is all wrong. Thoughts of the various lightweight drag wheels have come to mind, but again the backspacing/offset is all wrong. 7" width with 40mm/6" back spacing. A bolt on spacer could be used, but then it would just start adding unsprung parts/weight to the car. This car came with one of those 16" steel rims too, not much of a space saver and weighs nearly as much as the factory 205/70 R14 and Super Stock, typical GM goofiness.

Meh, adding a harness, and one of those jantastic 6L80E would be a project in itself. A T56 would be far easier to bolt in.

Heh, with that front end I dunno. Now a later model with the 2+2 nose would be the ticket.
For now I'll focus on cutting through the air, maybe filling up the panel gaps and adjusting the panels for a snugger/sleeker fit. Tuft testing is probably what needs to be done after getting a base line down.
