Thread: Supercharged Chevy 350 Build Help!

Tweet

Ok guys, this is my first post as a converted v8 guy so here we go.
I know little to nothing about v8s so be forgiving, I am used to the forced induction 4 bangers. So here is my question. I recently acquired a 1980 Malibu for a project car and I want to do nothing more then stick a small block 350 in there with a low profile blower and make a street / strip car out of it. Now realistically on my budget I dont know how many ponies I can make, but somewhere in that 450-500 HP range would be great! My question to you is what kind of motor setup do I need? My dad is a big Camaro guy and has a 350 sitting in his garage that came out of a bus. It needs a rebuild of course, but it seems like an good engine to go with. So what size of heads, carb, pistons, compression, rods, crank, cam, etc should I use for a descent street / strip setup. I know there are alot of factors, but any info is appreciated! Thanks!

1st off welcome to a great place to learn and get information about hot rodding. Let me start by saying that the words budget and blowers have nothing in common. You can get your 400/500 horse a lot cheaper without the blower set up. What are the #s off the block you have? Your best bet is to after getting a true positive I.D. off the block, run it down to a reputable machine shop for a cleaning and inspection for any flaws and cracks. Then get it machined and prepped for a 500 horse build. The only usable component from the motor will be the block and main caps, only if they are 4 bolts. I would use a 6" rod 383 rotating assymbly with some Brodix track one 2.08 aluminum heads. Along with a Brodix Intake and a Holley HP carb and a complete MSD ignition system. Cam will be determined by how much street and strip time it will be used for, and cars weight, rear gear, and tranny used.

You want a blower?

Start with forged pistons and crank and rods. Decide how much street time it will have and choose a cam accordingly. If your budget still has spending room, then a good set of aluminum heads ( practically pay for themselves ) Headers and exhaust.

it's going to cost.

I agree that you won't need a blower to make 500hp. I would be looking at a good set of aluminum heads (nothing wrong with Brodix, but I prefer AFR) I'd use the 195cc intake runners with AFR's, but maybe a little bigger with the Brodix heads. The fuel available to you at the pump will determine the static compression ratio you build into the motor (about 10.0:1 limit with aluminum heads, 92 octane and a tight squish of 0.035" to 0.045")and the static compression ratio will determine the camshaft. The camshaft used will determine the final drive gear ratio and converter stall. The higher the static compression ratio you use, the more you move away from street-friendly and into race motor territory.

I would do a 383 also, but would use 5.7" rods to prevent moving the pin into the oil ring like you do with 6" rods.

now come on guys what's wrong with a blower or 2???. Of course there right you can get 500hp easy without a blower, good heads,stroke it,headers and wham your there.

hmmmm. Kind of hard to see budget and blower in the same sentence.... They don't usually work well together....
