Summary:
- 1999 7.4L w/ 13,000 miles
- EFI Connection 58x System (58x crank and 4x cam for Gen IV ECMs)
- 2008 Corvette LS3 ECM and calibration
- Ram Jet intake manifold swap

We have the engine running with cam signal from the timing cover and (alternatively) from the distributor. Production EFI Connection 58x systems use a cam signal from the distributor.

This engine was used for prototyping and is now for sale. More at http://www.eficonnection.com.

LOVE the window exit exhaust !!!!

So can we get that to work with a 4L80E and tap shift ??


good work

Yes...or even a 6L80E/6L90E and tap shift!

Newsflash, LS1 PCM and E38 prices have doubled in the last 6 months due to high demand from the conversion companies :hihi:
Nice job, again!

Spare ECM on ebay has consistent prices.......

It's a production 1999 7.4L Vortec engine. This would be a fantastic system for a 502ci Ram Jet.
