I was actually contemplating doing this almost exactly. Take a 6.0 block and a set of LS2 pistons and balance them with a 4.8 crankshaft and rods, bushing the rod ends if needed for the floating wrist pin. Then take the L92 heads with a nice valve job on them and a custom spec cam, whip together and viola! Install 1900 TVS to flavor and increase low end torque!
At least that's the motor I'm dreaming up for my '06 GTO.

sounds good to me! this is a combo i want to do on my front engine dragster. 301's were a popular small cubic inch motor that packed a punch. 327 with a 283 crank. i see some of the dirt track dudes run 2.9" stroke cranks. hello 10k rpm. anyway.. yes swap the (6.2) l92 in the truck they put down very impressive numbers
Of course being a light weight front engine dragster, it may be interesting to see the outcome of such a package. One thing to keep in mind though, is back in the day when the small cube motors like the 302 was around, they were using heads that were marginal for the larger motors, so the smaller cube motors were really able to make better use of them. Hell, the stock heads we have now are somewhat on par with the Winston Cup heads from the eighties and in some cases better.

they will not fit me and my friend tried mine on his ls1 with a 500 lift cam and the valves would rub aginst the side of the cylinder walls and that was bored .010 over to...
