3rd Gen Hemi - gearbox conversions?

Try http://www.quicktimeinc.com/products.html for a SFI blow-proof rated, spun-forged bellhousing.

I have RM-6071 MOPAR Bellhousing/TKO 500-600/T5 Mustang/TR3550 for my upcoming T-5 swap. You may be interested in RM-6070 MOPAR Bellhousing/Chevy Transmission if you are sourcing a Holden transmission.

I have one of the first production runs of the RM-6071. It is a niece piece of engineering. I have heard great feedback from others on Quicktime's quality.

By the way, 3gen hemi in Dodge Trucks had the Chrysler designed & built 545RFE auto. It is a derivative of the 45RFE auto but has two overdrive ratios and uses 5 ratios in its normal shift sequence. The M-B sourced auto is the W5A580.
