Hey Scott, I'm building the 25 30 to lol. It's going alright, just a bit of talking and planning with dan from erd on the best way to go. Since talking my builds already doubled what I though it would. I have a fully built head with a lot of work done to it, just bought an npc twin plate clutch to handle 1000hp at the wheels. Getting under car surge tank made up in progress, working on getting harmonic balancer from Ross, but dan thinks I should look at getting the Ross trigger setup to, which is an extra $2000. So I'm not sure on that one yet, how did you go with your engine regards to timing at 4000 and 7000rpm? No jumping around or anything? And still deciding on oil pump, which will probably be a nitto pump, these are things I didn't plan on the 1st stage of the build but need all the above for balancing
