I had a good friend call me last night. And offer to sell me everything he had for a gen 3 deal he was putting together to run a 275 class locally. But decided to go another direction because of rocker arm prices. His heads flow great or at least I think they do they flow 385 on the intake have new bigger valves I can get them and everything else just doesn't have a crank rods or pistons for 1000 thinking about getting that an do another motor completely an just put this one to the side or sell it mine has 32000 miles on it.
