I’m stuck between a rock and a hard place. Just when I think I’ve made up my mind, I change it. My goal this year was to not purchase anything I didn’t need so I could save up for a nice engine for the ‘74. I mostly built this car to be an autocross car that I can happily drive to work, the mountains, etc. I’ve done nearly every bolt-on to the car, going for the fast-slow car ideology. TKO600, C5 brakes, 3.73 gears with a Detroit locker, full PTFB and CustomWorksPerformance suspension, among other things. The car already does very well in my area’s autocross sanction, usually getting top 3 of each group with relative ease. The main thing holding back the car now is the tired, old, and original 350. In fact, I’m surprised it hasn’t blown up on me yet, as I really ring the thing out. It’s been enough to make the car somewhat competitive, and it’s surprisingly fun, but it’s time for moar powah. As for power, I THINK I want something around 400-450 HP. I dyno’d my car when I first got it, before some upgrades, and the 350 only made 190 HP to the wheels. 400-450 would be, I think, a good compromise for something cheap, fast, and reliable. I’d stick with an SBC mainly because of how much cheaper and easier it would be. If I did, which engine would be best for my application? It would most likely be a Blueprint 383 or 400, but I feel like they cater more towards people who want torquey cruisers to lay rubber at their local car show and not for spinning and shifting at high-RPM’s for autocross. Am I wrong about this? A 377 or a 302 would be fun, but if I stick with the SBC route, it’ll be because I want something turn-key and budget friendly. An LS, though, would easily get me everything I’m looking for, and I know that once it was completed and running, it would be worth it. I just don’t have the time and money for it right meow. A cheap bolt-on LS1 would be perfect, but it seems daunting. Again, I need to stress that I’m on a budget. My plan to save money all year changed when my son was born last week, so I want to see what I should realistically be doing with my money and how much I should expect to spend? Thank you!
