Spencer,
My engine started life as a MAF system, but I converted it to SD due to the plumbing issues (and I find the MAF a bit ugly
).
I just took a complete wiring harness and ECM from a 92 IROC. There is a lot less wiring needed then there is for the MAF.
I used the old power wire for the coil to trigger the main relay to feed everything else under the hood.
If you do go the MAF route, you could drop the charcoal canister down into the inner fender and mount a Camaro canister air filter in its place.
A company called JTR (Jags that run) used to carry all kinds of elbows and bends for the intake.
If you take an old style sbc thermostat housing, you can mount it backwards on the TPS intake to make room for the upper rad hose. The TPI housing stuck out so far it almost touched the rad.
Now that I have AC, the alternator has been moved to the drivers side, so I had to modify the upper rad hose even more to make room. The mechanical fan has been replaced by a 16" SPAL to make room for the Griffin aluminum rad.
I'll post an updated picture later this week.
E-mail me if you have any questions on getting it all to fit.
Cheers,
Tim
