I know these are very expensive but I havn't had any problems since after going thru 4 sets of wires and them burning on the headers. Just my 2 cents.
That's actually the vacuum solenoid that is part of the AIR pump system and it usually mounts to the front of the AIR pump shutoff valve in the slotted groves but had to be moved as it was in the way.
your 383's emissions legal? didn't think texans had to be. if the internals of that LT1 are as clean as the externals, I'd love to hear about it.
anyhoo.....the delteq looks spot on here, may seriously do some re-considering before the next swap-ti.
I don't argue that multi coil setups are technically better, what I argue is that they are not worthwhile for the overwhelming majority of guys, the opti works great, so keep it as is and spend the money somewhere else.
