Moreover, to work around the limitations of the stock PCM, Ben spec'd out a custom 259/267-at-0.050 solid-lifter cam that peaks at 6,800 rpm. They have been rubbed on by Meaux Racing Heads (Abbeville, Louisiana) to flow 289 cfm on the intake side and 230 on the exhaust. That put an even greater emphasis on the selection of top-end components, so the cylinder heads of choice were 210cc units from Air Flow Research. Typically, sliding in a big, nasty cam and zinging out the revs can compensate for a shortage of cubes, but there's that rev-challenged stock PCM to deal with, and Ben didn't want to spend the bucks for a stand-alone EFI system. Stuck with the factory block, Ben used splayed four-bolt main caps to make the most of a less-than-ideal foundation for building power. 030-inch overbore with a 3.875-inch stroke. ![]() The first compromise was settling on a modest displacement of 396 ci, achieved by combining a. Clearing the aforementioned hurdles required a combination of ingenuity and compromise. But instead of ditching the LT1 like most hard-core F-body enthusiasts, Ben Moore built a car that can handily stomp most LS1s. Suddenly, the view from second place doesn't look so good. With Vortec-style aluminum cylinder heads, poked and stroked LT1s can easily crack 550 hp with factory castings. Instead of relying on the archaic, time-based ignition systems of the day, the LT1's Opti-Spark system used optical sensors to precisely identify the angle of the crankshaft within 1-degree increments, affording individual cylinder timing control and a more aggressive spark curve. Reverse-flow cooling, which routed coolant into the heads before the block, allowed for an astounding 10.4:1 compression ratio on pump gas. ![]() Nevertheless, the modern tweaks engineers infused into the old-school Mouse motor to create the LT1 firmly fortified its status as the pinnacle of traditional small-block Chevys. After all, we're comparing the product of mid-'90s engineering to a design that traces its roots back to the mid-'50s. I have a 1994 camaro z28, the air conditioner was. Sometimes it revs by itself at a stop and wants to pull forward read more. Compared to the LS1, does the LT1 really suck that much? Sufficient evidence certainly exists that suggests so, but that isn't so much a sucker punch to the LT1's ribs as it is a testament to the progress of technology. Car starts hard, acceleration stutters after 5 minutes of driving but clears up when wot.
