Hi guys. First off, let me say I am still learning these cars, so please go easy on me. I'm torn on which route to go for my power plant. What I do know for certain is I don't want a boosted application, or an LS1 swap. The car is still drivable but the motor is finally giving up after 228,000 miles. I will likely rebuild my 2V or pull it for a 351 roller carbed build. My goals are simple: #1. Get as much power as I can out of 91 octane crap gas they sell in California. #2. Beat my friend who has a 00 Camaro with full bolt ons and a 175 shot #3. Hear that beautiful 7,000 RPM symphony I'm confident I can accomplish these goals since I have a 400 pound weight advantage. Plus, I'm not afraid to use race gas when we go racing. I've been trying to learn as much as possible about both set ups, but it sounds like the 2V 4.6 is only good for about 425 HP. Is this correct? Obviously a bored and stroked SBF is good for more, but at what cost?
