The Texas Speed SFI High Integrity Quick Rev Flexplate is a direct bolt-on replacement for the factory flexplate, built for high-performance builds that see high rpm and hard use. It is stamped from cold-rolled premium steel at .035" greater thickness than a stock plate, and the 168 tooth ring gear is a forged one-piece steel gear that is double welded to the plate. The plate is internally balanced and finished in a long-lasting gold irradiate coating to resist corrosion.
This version is made for GM LS engines with the 6-bolt crankshaft flange and is drilled for five converter bolt patterns: 3 x 11.00", 3 x 10.75", 3 x 11.50", 6 x 11.50" and 6 x 11.00". That covers converters for the TH350, TH400, 700R4, 4L60E and 4L80E, which makes it a flexible choice for LS swaps into older GM vehicles. Texas Speed notes that an older small block Chevy style converter may also need the TSP crank adapter sleeve (TSP-00346) to center on the LS crank.

FAQ
What transmissions does the Texas Speed Quick Rev 6-bolt flexplate work with?
Texas Speed lists it as compatible with TH350, TH400, 700R4, 4L60E and 4L80E transmissions behind a GM LS engine with a 6-bolt crankshaft flange, thanks to its five converter bolt patterns.
Which converter bolt patterns are drilled into this flexplate?
The TSP-34614 Quick Rev flexplate carries 3 x 11.00", 3 x 10.75", 3 x 11.50", 6 x 11.50" and 6 x 11.00" torque converter bolt patterns, covering both three-bolt and six-bolt GM converters.
Do I need the crank adapter sleeve with this flexplate?
Only if the torque converter is an older small block Chevy style unit. Texas Speed notes a crank adapter sleeve, part TSP-00346, may be required in that case so the converter centers on the LS crankshaft.
How does TSP-34614 differ from the TSP-34610 Quick Rev flexplate?
Both are SFI 29.1, 168 tooth, internally balanced premium steel plates. The TSP-34614 is stated for 6-bolt LS cranks and adds the 3 x 11.50", 6 x 11.50" and 6 x 11.00" patterns for 4L60E and 4L80E converters, while the TSP-34610 is drilled only for 3 x 11.00" and 3 x 10.75" (TH350/TH400).
Is the Quick Rev flexplate SFI certified?
Yes. It is SFI 29.1 certified, built from cold-rolled premium steel .035" thicker than stock with a double welded forged one-piece ring gear and a gold irradiate anti-corrosion finish.
