Ok, I have been given a good deal on a used 350 that I Don't want to pass up. I'm going to build it, but I'm not sure what I'm putting it in yet lol

Anyways, I am looking for 350whp and roughly the same torque out of this. It is staying carbed. I'm open to suggestions, too.

I've heard a lot of good things about stock vortec heads, and I can find used vortecs for dirt cheap. I'm thinking of getting them and having them rebuilt, port polish and either thinner metal shim headgasket or milling the heads down to up compression. I've talked to a few people that have said they love their lt4hotcam, they say its a great "mild" cam, lopey at idle and great power, but not "too much cam". So I'm thinking about that and a high rise intake with a holley 750 on top. I will do an msd coil with either 8 or 8.5mm wires and if using vortecs, probably bosh platinum +2s' I believe they are called.

Can anyone tell me roughly what kind of numbers I would see from this? Anyone want to make suggestions? The budget is basically the cheaper the better, but I'm willing to spend money where its needed.

 

Bump

 

If you get a good 350 i would say depending 275 to 300 crank imo, depending if it's a 79 truck motor or a later vortec 350? About 240 to 300hp.

 

What did it come out of?

 

buying vortec heads and rebuilding them is a waste of money. By the time you're done, you could've gotten a GOOD set of used (or like in my case, completely refurbished ready to bolt on with port work) aftermarket heads for about the same price.

350 rwhp isn't monster amounts by any means, but it will take more than simple plug and play parts to get there... and buying a shelf cam is a joke. I seriously don't get WHY people go this route anymore. I know it's easy, but it's the #1 reason why people get so disappointed with their cars half of the time. Get someone who specializes in cams to build you a stick that is unique for your application.. do that and you will have a much easier time hitting your power mark and gaining a lot more in the process.

Remember that building a motor is all about balance. I can't tell you how many people I've seen sink thousands into a motor just to get spanked by a $300 junkyard motor simply because the other person actually decided to do their homework and talk to the right people (who also.. do their homework on a regular basis).

Get a good set of heads, a good carb (Proform, Quickfuel, AED, Prosystems, whatever your preference) and call a specialist to grind a cam out for you.

 

These guys are a good source for a custom grind cam.
