The PRC Small Bore LS7 cylinder heads are designed for both stroker, and stock cube applications with a 4.060"-4.100" bore.  For bores larger than 4.100" bore checkout the PRC LS7 265cc & 285cc cylinder heads!

The PRC LS7 cylinder heads are available with hollow-stem intake and titanium intake valves. We recommend no more than .625" total intake valve lift with the hollow-stem intake valves and no more than .670" total valve lift with the titanium intake valves.

TSP Stage 3.2 LS7 N/A Camshaft

$389.99 Save $-389.99
Our new and improved LS7 Stage 3.2 camshaft has taken what was already a proven camshaft and made it even better!  With our countless hours of testing on our SuperFlow 902 engine dyno, we were able to revise all of our LS7 camshafts for better power everywhere in the RPM band!  All camshafts were designed using a factory GM 7.0L LS7 engine with no other internal changes.

This camshaft features custom-ground lobes specifically designed for the LS7! These lobes not only make excellent power throughout the entire RPM band, but they are also much more stable.  So, this equates to a quieter and longer lasting valvetrain compared to most other comparable camshafts on the market.  Like all TSP camshafts, they are 100% developed, ground, and polished in-house using our state-of-the-art Landis CNC camshaft grinders!

2800 - 6900 RPM Power Band; This is an excellent performance camshaft with an aggressive idle!  Custom tuning will be required for this camshaft.  It will have a lopey idle and will pull hard through the mid and upper RPM band.
Cam Specs: 240/252, .657"/.655", 111 LSA (Lift w/ 1.8:1 LS7 Rocker Ratio)
