Hello!
This is my second time on this forum and the first time, y'all helped me fix a pesky oil leak on my buddies and my 1980 malibu street car. For context, we're two 19 year olds who love cars and rebuilt his blown (cracked piston) small block into a respectable 383 stroker sbc in his dads living room. The motor has a holley street avenger 650 cfm vacuum secondary carb (which we plan to swap), speed pro pistons, scat rods, arp rod bolts, comp cams camshaft, liberty performance rockers, and dart iron eagle heads. This summer we were happy to finally take it to the track and after adding slicks, the car ran a 12.71 @ 113 mph in the 1/4. We were happy with it just making a pass but I'd say those numbers aren't horrible for a couple of newish guys to the sport on a budget. That being said, we obviously want to go faster as anyone would. Neglecting the fact that we grenaded the th350 the last time at the track, were looking to step into a REASONABLE nitrous kit. Maybe a 125 or 150 shot? The car is running roughly 9.2:1 static compression ratio with acdelco r43 plugs. The ignition system is an MSD Pro Billet with an MSD ignition box running it (currently set at 15 degrees base and 32 degrees total). We're thinking just a plate system under the carburetor. I want to ask y'all who obviously have more experience with this stuff than we do, what you guys recommend and some tips. I'm assuming the basics like a wideband sensor to be safe and retarding the timing and all but I'm still nervous. We've invested too much of our limited time and money (being full time college students) in this car to melt it down first pass. I just want to hear what you guys have to say. Thanks in advance!
