my dad is planning on running a 144 blower on his new GM Goodwrench 350/ 260 HP engine, with the low boost ( 5-7 PSI ) pully's, Holley's site and the instructions say this is all good, but when I suggested to my dad to get a blower specific cam, he says he's "drawing the line" at putting the blower on, he says that it is all he needs. now I know that the cam it came with is a very small cam, I told him he would get way more out of it with the blower specific cam, but still insisted it wasn't worth it. I actully think the cam is too small for a blower, and would keep the cyl preassures up and cause excess wear. he is more worried about getting the timing dialed in W/O pinging, so he can run the engine on the edge of detonation ( using Knock sensor ), so he can pick up 10 HP, rather than leave it in a safe zone. he's gotta replace the radiator anyway, and the grill only screws in, changing cam wouldn't be that bad. here is the full engine specs
