The new LT1 may be out from GM, but the go-fast world still has a strong love affair with the LS-series of engines. COMP Performance Group (COMP, TCI, RHS, FAST, to name just a few) had a ton of new, and soon to be released, LS parts on display. For the hardcore racers RHS has just introduced their LS Solid Aluminum Race Block. This is just the ticket for the drag race market and fits within rules that do not allow billet blocks by specifying they must be cast. A solid water jacket design featuring A357-T6 aluminum provides superior strength and improved rigidity that’s perfect for crank-mounted superchargers and blowers. It also has all the features of their standard Race Block including 6-head-bolt design (head stud fasteners’ diameter has been increased to ½-inch) and the new block comes in both standard and tall deck configurations. Best of all it’s a fraction of the cost of a billet block.
COMP was also showing off their new LS Gear Drive Timing Set. This is a bolt-on deal for LS engines used in racing, street, marine, and other extreme applications. This gear drive provides the most accurate valve timing possible by eliminating chain flutter and backlash. The drive requires no modifications and maintains the stock oil pump and timing cover (except dry sump systems). They are available for both 24x and 58x engines.
From TCI there was a new Auto-X GM 4L60e transmission that can be paddle shifted and offers engine-braking which was previously only available to those with manual transmissions. Their 6X Six-Speed transmission offers, as you may have guessed, six forward gears and is fully programmable. It can also automatically shift or be manually shifted. The TCI EZ-TCU computer runs the trans and they also offer a range of torque converters to suit your driving style.
FAST had two super cool new items that will be out soon. The first was the fact that all of their intake manifolds will be offered in the ever fashionable black color. We liked the grey, but it was a bit tough to keep looking good. They were also showing off their new 102mm throttle-by-wire throttle body. Yep, this is what all the fly-by-wire guys have been working for. In addition to more airflow it also is profiled for smoother idle characteristics. RHS also were showing some prototypes of their new LT1 and LT1/LS hybrid heads. The first will be a replacement for the new GM LT1 engine and the second one combines the improved design of the LT1 into a head that will bolt to an LS engine (using LS-style rockers and valve covers, but an LT1 intake manifold). Add in conical valve springs (both single and dual) and there was a ton of new parts to drool over at the COMP Performance Group booth.
